Jin-Yi Yu: Away for one more minute.
Jin-Yi Yu: Anyone's still coming
Jin-Yi Yu: Okay, so
Jin-Yi Yu: At the end of our an obese child tell you a little bit more about the mitten answers to the format and how you're gonna do it and put it first. The media continue to finish the discussion on the most practical general circulation.
Jin-Yi Yu: So can everybody see the popcorn right now.
Jin-Yi Yu: Okay, so let me know if
Jin-Yi Yu: For any reason that it cannot see the hosting
Jin-Yi Yu: Last now already explained that the general circulation, you know, thermosphere can be described by these three sales model which we
Jin-Yi Yu: Discussed that we showed out in the tropical region, we have a heart resale basically from the equator, so that it will not. And then in a polar region from $16 to the
Jin-Yi Yu: Whole north pole, south pole. We have a policy on you in between. We have a fire sale, but for sale you are, sir. But most important is this
Jin-Yi Yu: Holiday sale where the same time. Last time we disquiet at the association in association with these are three sale model, you will expect to see a low pressure in the load it in equatorial region and a high pressure in the subtropical region.
Jin-Yi Yu: So you're supposed to have a subtropical high across the
Jin-Yi Yu: The earth in about 30 degrees nose. And so typically south and about 60 degree North and South, neither polar region, we have a porno low
Jin-Yi Yu: low pressure system here and then at the high Apollo. Originally, we have high. But as I mentioned last time that because the surface area covered by this policy is
Jin-Yi Yu: Very small. So, usually with the nap.
Jin-Yi Yu: Pay particular attention to this policy, of course, in recent years.
Jin-Yi Yu: The risk climbing research community pay a lot of tension or a porter climate. So this area become a very
Jin-Yi Yu: intensity, intensity study and very hot research subject before our class occasion is going to remember this resell it. Remember when we are expected which loud you we are expected to
Jin-Yi Yu: See low pressure high pressure low pressure, pressure, and then in the app away from the surface near the top apart, we are supposed to see to jet stream. When is the so called subtract coated
Jin-Yi Yu: With s and there is another one called politics. So this is something you have, we have to recognize in our apple troposphere.
Jin-Yi Yu: Where the zone, no wins, be a very strong with those instruments we would call the jet stream and we should remember they actually have two
Jin-Yi Yu: Different just trim. I'm going to come to this one later on. So the key thing to remember is all these resellers occasion.
Jin-Yi Yu: The inner surface. What would you expect to see in the upper troposphere. What do we expect to receive or something.
Jin-Yi Yu: You have to remember. So now let's compete. See this one is another way to look at history sell security see that this is
Jin-Yi Yu: Equator here. So yeah, one sale how the resale final sale wholesale and we can see that arising branch of this, how they sell an equatorial regions caught in traffic or converting on it CZ
Jin-Yi Yu: An RTC as you can see that if you look at the sutra picture because he
Jin-Yi Yu: A little bit to the north of the equator very close to the equator. You can see continue pen or cow across 360 degree over the whole earth. And then that's the whole record into
Jin-Yi Yu: Tropical converging on and then here at about 30 degree nose or statistic which sells the holiday season has a sinking branch in a sinking point, as I mentioned as high school because he come down from high that
Jin-Yi Yu: High altitude to lower altitude and compressed and become warmer and warmer and also very dry.
Jin-Yi Yu: And so equal economy produce a high pressure. So you can see this somewhere around $13 and 30 cents. We're supposed to high pressure
Jin-Yi Yu: And high pressure supposed to suppress convection. That's why you can see this whole area of ocean is no crowd and over then area going to have tears.
Jin-Yi Yu: And similar thing here in the in the North America and then further to the north to 60 degree not then you will begin to see some low pressure system developing
Jin-Yi Yu: Yeah. So those are the three things to remember. And then, as in associate with this three sales occasion this low, high, low, high,
Jin-Yi Yu: And we took in
Jin-Yi Yu: This
Jin-Yi Yu: Though subtropical high polo
Jin-Yi Yu: In those other support. Oh, let me see. I should. More precisely, it is sub polar low
Jin-Yi Yu: About 60 degree north and south and then we have a
Jin-Yi Yu: Sub
Jin-Yi Yu: Tropical
Jin-Yi Yu: High pressure
Jin-Yi Yu: And you can see that you look at the
Jin-Yi Yu: Map. This is our pressure map. And this is a kamikaze
Jin-Yi Yu: I mean after we every to for a long time, or a January from, for example.
Jin-Yi Yu: Something, something, a we have a January math in Edit together and then you produce this continuity map.
Jin-Yi Yu: And because it every so many years of January together and look at this picture. So this means that AV ears every January, you can in any year very likely you're going to see all this pressure future in the global map and Lucas. Lucas. Okay, here this is equator somewhere around here.
Jin-Yi Yu: So immediately near the equator, usually a bit to the north.
Jin-Yi Yu: You can see the particular ocean so so ITC tend to stay to the north of the equator ocean but overland you can more or you can
Jin-Yi Yu: Put a saucer equivalent or North equator. Follow the season when the northern hemisphere is summer in Oberlin area it CDMA moved to Northern Hemisphere.
Jin-Yi Yu: When some more to southern hemisphere become Nolan winter and southern summer. Then it says he may move to south of the equator overland area, but over the ocean, the IPCC always stay to the north of the equator. And this is something that
Jin-Yi Yu: meteorologist and scientists, we still cannot explain completely why he now real war, the IPCC over the ocean always stayed to the north of the equator user is between five nodes to 10 nodes.
Jin-Yi Yu: And this is also something that can be model today still cannot produce this
Jin-Yi Yu: Now, or tomorrow can produce these because in the coming model over the ocean. The room for families IPCC some model most around a model, they will move north and south north or south across the equator. Follow the season. There's someone has a question.
Jin-Yi Yu: Or it CC stand for in tropical converging on
Jin-Yi Yu: I saw, I wrote somewhere here. No, I didn't.
Jin-Yi Yu: IDC is a very, very important.
Jin-Yi Yu: Terminology and future so IPCC
Jin-Yi Yu: Means in
Jin-Yi Yu: Tropical
Jin-Yi Yu: Trees i is in team is tropical and seeing his column will jeans zone.
Jin-Yi Yu: Okay, does this is where a coming this no software when in the northern hemisphere comes in to enter salsa equator. We have South East trail and comes in.
Jin-Yi Yu: So the noise is trail and come in, meet with South Eastern wing and it has no way to go because it covered in this region, and then they have the rice. That's why we produce this this rising branch of the hardware itself.
Jin-Yi Yu: And this in the tropical convergence on is a very important future when we study the climate change, global change we study
Jin-Yi Yu: Many, many things. People will always mention it CZ and this is something that
Jin-Yi Yu: Tiny model still cannot reproduce this observation observation future which is that over the ocean, the IPCC always shoes state to the north of the equator. So they sell them cross the equator to South
Jin-Yi Yu: Of the equator, even when the northern hemisphere become winter that you thought that the sun is shining directly over the southern hemisphere.
Jin-Yi Yu: Then the warm water will appear to the south of the equator than all the Cambodian shoe convert to the south equator, but he didn't happen in real the
Jin-Yi Yu: IPCC. As you can see here is always stay for another equator nausea equator only overall an area I can present. This is equator is my power.
Jin-Yi Yu: You can cause go south equator. And then, importantly, our season move knows our equator. So we can see if you look at the best look at sea level pressure distribution.
Jin-Yi Yu: So here you can see it. I put is Teresa security here. So any equator here a positive is this one.
Jin-Yi Yu: And they can see that, or a arise produce it CZ as my always room for Ben is here.
Jin-Yi Yu: And then one a go north and come down to 32 winners here, somewhere around 30 minutes
Jin-Yi Yu: You can see that we are supposed to see high pressure is either is high pressure here in the Pacific. That's called pieces Hall.
Jin-Yi Yu: See big high
Jin-Yi Yu: Or somehow we call how why he can hide.
Jin-Yi Yu: In the Pacific in the Atlantic will also see another high as called by Moda high. But then of course inside hemisphere, a certain result.
Jin-Yi Yu: You see this high pressure high pressure high pressure across the Southern Ocean and then we go to 62 winners. We hope to see a sub polar low so equal to 60 degree lost somewhere around here.
Jin-Yi Yu: So you can see that this audience them though over the Pacific and this dough over the Atlantic is called Iceland. Oh, OK. So those are the name, we need to remember. So the support is for the Northern Hemisphere. So in a non MSP over ocean area in the Pacific.
Jin-Yi Yu: And in Atlantic
Jin-Yi Yu: We know we have a south pole sub tropical Hi, this is called Pacific high or how are you and I are we're perceiving the subtropical high or what branding is called Armada arrows are are also Reese high
Jin-Yi Yu: And then this is support low in the passivity is called audio said no. And in today's call Iceland not also. So we what we call the semi permanent
Jin-Yi Yu: Pressure cell why we say semi permanent because these low and high pressure, they tend to change their strengths. We season, for example. Now let's look at support a high
Jin-Yi Yu: See here, Lisa Percival Hi Amanda hi during winter time. No, no. Linda can tell is relatively weak is that we see that this
Jin-Yi Yu: Support or no are you know in Iceland know a very strong during winter time. But when you move to the northern summer July, you can see that
Jin-Yi Yu: Again, the, how are you have become very, very strong. My mother had a very strong in our new Sandow in Isla no become very small number has some a question.
Jin-Yi Yu: Let me see it first.
Jin-Yi Yu: Okay, so you can see that during summer.
Jin-Yi Yu: We have very strong suck tropical
Jin-Yi Yu: High
Jin-Yi Yu: But during winter we have very strong sub folder low
Jin-Yi Yu: And now let's try to understand. That's why cause semi permanent. But still, most of heights. You can see these two and this Apollo in the wintertime is very, very strong because during the winter time over ocean post ocean and then cool down, but then call them more. So we have
Jin-Yi Yu: Very, very cold, then at the same time, we have relatively warm water. So one area should produce the pressure. And that's why the supporter low tend to be stronger in the winter time.
Jin-Yi Yu: And similarly, if you go to summer time then then we become braver or an ocean compared to learn is Rob three relatively coat. Everyone is CO is easy to build up high pressure. That's why the sap polar a subtropical high tend to be strong in summertime.
Jin-Yi Yu: Because high pressure over ocean, it will be strong during summer because ocean or colder than then
Jin-Yi Yu: The supporter, low, low pressure will be strong during the winter time when that ocean is rotting warmer then ocean.
Jin-Yi Yu: So it does this is very important thing to remember last minute high and low subtropical high end support a low name for each of ocean pacing.
Jin-Yi Yu: The other thing we need to realize is why our lows south pole low end subtropical high important first when we are in the winter time when the support. Hello, a very strong this
Jin-Yi Yu: Audience and no in Iceland. Oh, determine where the winter storm is calling to move
Jin-Yi Yu: And that's where it's going to hit united state or hit your Europe, European area so dealing with a kind of an auto mechanic you winter storm activity.
Jin-Yi Yu: Is controlled by the strings and location of these tools Apollo one issue my issue was walk or getting stronger or weaker is going to determine affect how many
Jin-Yi Yu: Windows somehow strong winter storm. We are going to encounter over North America and European area.
Jin-Yi Yu: In the summertime. This subtropical high are particularly strong then if you pay attention to TV news during the winter, summer in the autumn time. That's where we have a hurricane in the Pacific or type them in the western
Jin-Yi Yu: Union Atlantic in Python western Pacific and where the title is going to move where he's from America them for his come tour by the orientation is strains of this subtropical hi I'm good are high in the South Pacific high for example this year.
Jin-Yi Yu: So far in the western Pacific all the type of them has been all most of time phone call, only two one go directory to include China to Vietnam.
Jin-Yi Yu: Or in the early part of the summer or in time from this year in 2020 in the past few
Jin-Yi Yu: Few months all the type of move away from western Pacific in a topic and and go all the way to Japan and Korea. And the reason is because this year.
Jin-Yi Yu: We have a very, very strong subtropical acting and locating more
Jin-Yi Yu: To the north compared to normal occasion in this way this subtropical high because this year in the Pacific in movie was located
Jin-Yi Yu: Much higher latitudes and they are very, very strong. So effect order when a phenomena in East Asia. So this one cost the that for most of these
Jin-Yi Yu: That Nina Philippine Taiwan and an invalid China area really the past summer, a lot of area Pina observed or encounter any type of
Jin-Yi Yu: This year, because all the high level has been still to the to the rapid moved to Japan, Korea and northern part of the China at the same time because of this very
Jin-Yi Yu: Very unique location of subtract this year in the past summer, so the rainfall patterns internal East Asia become very, very strange this year. So this subtropical high in the summertime determine what kind of weather extreme event. We're going to encounter and during the wintertime. This
Jin-Yi Yu: Sub polo audience and knowing I said no, it's called determine how much rainfall or whether or not we're going to have
Jin-Yi Yu: Extreme weather event to occur over the North America and Western European area. So these are those those full name, low and high pressure. The one we need to remember. Okay, now let's continue to discuss associated with this.
Jin-Yi Yu: To sell security. And as I mentioned, up in a tropical region. The rising branch or hot resale.
Jin-Yi Yu: Cold air goes up produce our aim for in the equatorial region. And that's where we observe a tropical forest.
Jin-Yi Yu: In a single page of the heart the sale because all the water vapor will arise equatorial region already condensate and drop out.
Jin-Yi Yu: Of family atmosphere to become rain for so they become a better driver with joy and then we move to study the queen knows we have very dry air in the upper troposphere in this area was
Jin-Yi Yu: was pushed down to go to the surface and compressed compression and warm up so very comfortable surface. The air become try and very warm and that's where we
Jin-Yi Yu: Produce most obesity region of the world as a whole. So the most of the desert region over
Jin-Yi Yu: So this is a branch of the holiday sale when they seem to the to the ocean surface they put deals passivity hi and Pamela. Hi, but when this sinking. You go to the land that produce pairs.
Jin-Yi Yu: So you can see that if we look at a strategic way not so directly south, and this is sinking brain to have a healthy sale. You can see Mojave Desert in California and in Africa in Africa, in Asia and in
Jin-Yi Yu: South America southern part of Africa into Australia those other region we reserve fencer because they happen to located right underneath the sink in branch of the heart of the sale.
Jin-Yi Yu: And the last thing we notice from this resale security is a size mention inside service dough and high pressure, the
Jin-Yi Yu: Casing associated with these three sell security in the mirror purple a troposphere troubled past, we have to strong jet stream stream is defined as very strong when in the apple troposphere and we can see that we in the real world. So here you can see that this is equivalent
Jin-Yi Yu: This is North Pole. So this is only half of this
Jin-Yi Yu: So we sell this we process each hemisphere. This equator assume the sale. So you can see that we have to just dream about it, each hemisphere. One is documented somewhere around 30 degree knows this one we call sub
Jin-Yi Yu: Tropical chip. And then the other one we have very, very strong winds be observed around 60 degree knows that's what we call reporter yet.
Jin-Yi Yu: And this example, it can see that the winter john law mean when component
Jin-Yi Yu: In northern hemisphere located at 100 for the decrease in particularly in this particular location and actually be is there is, you know, decrease
Jin-Yi Yu: And the reason we need to this particular pay attention mentioned this, don't get too is that usually, usually in the Northern Hemisphere. You cannot. We will not absorb this to
Jin-Yi Yu: Suffer the two gesturing separate from each other. You're in a northern hemisphere.
Jin-Yi Yu: Because we have 11am mountain. So this total stream cannot stay at 70 degrees north and 60 degree. Now we can see them separate from each other because the mountain is going to produce way the motion. So, this
Jin-Yi Yu: Gesture intend to will be up in dumpling the up and down. And so most of it or marriage together so
Jin-Yi Yu: Most of the time in the Northern Hemisphere. We do not expect to see this to just trim separate from each other, they tend to stay very close to
Jin-Yi Yu: Each other and got a sub chocolate yet here and a polarity almost much to each other. However, when you go to southern hemisphere, where we do not have a mountain or we do not have a lot of land this last
Jin-Yi Yu: Season distribution, then you can see that will clear these. Let me see if I have a map. I do not have a map. So in the southern hemisphere. We can clearly see two separate gesturing one
Jin-Yi Yu: Let me move to a global map.
Jin-Yi Yu: Here, use this one, you can see that will have one gesturing passing somewhere around Australia. That's why we call this subject tropical tip. And then we have another test.
Jin-Yi Yu: Passing sue the whole had to pass in New Zealand. THAT'S A PRIORITY, but in the Northern Hemisphere, because we have a month, a year, we have him.
Jin-Yi Yu: Rocky Mountain, we will have to pay per row. So this tool, we cannot directly see tools on distribution of subtropical and project because this chip will get
Jin-Yi Yu: The sprays North South or North or South up into the mountain. So a lot of time they become merge to each other.
Jin-Yi Yu: Merge to each other. So only over western part of the United States. I'm going to describe the outside, for example, California. You can see this
Jin-Yi Yu: Horrid just trim and sub chopper jet stream secreted very clearly. But most of the northern hemisphere update to the long term leverage
Jin-Yi Yu: This to jet stream or merged together. Okay, so this is the important future associate with a stories sell security, we need to recognize that means near the apple Papa sphere C 100 minibar co engineered we have very strong wind speed, which is positively burial and I means Western when
Jin-Yi Yu: I mean is greater than zero. And because with the federal
Jin-Yi Yu: Coordinate this
Jin-Yi Yu: X cornice way. So when x is this zero when x is positive when school nice way from west to east Missouri call eastern region. So you can see that
Jin-Yi Yu: We have torches free one in the subtract. But here we are in politics.
Jin-Yi Yu: And okay somewhere near the top apart.
Jin-Yi Yu: On can see apple
Jin-Yi Yu: troposphere.
Jin-Yi Yu: You can see that because I mentioned, because we have been mountain where Rocky Mountain year
Jin-Yi Yu: And we have the paper here. So in this gesturing. For example, the support yet and political entity this mountain near
Jin-Yi Yu: Where the emotion is what and then we have an RP mountain in the euro HR range. So we have three the mountain range in the Northern Hemisphere. That's why this gesture no longer become a circle.
Jin-Yi Yu: Instead they produce up in time up into a three network number three structure. And then similarly, the politic affected by the mountain to produce we're number one, we're number two with number three.
Jin-Yi Yu: Is we're number one women to industry. So we have always seen this week number three pattern occur over the sub topic here and politics.
Jin-Yi Yu: And you can see that most of kind of a merge each other, each other, each other area, we cannot see. We can see the
Jin-Yi Yu: Support supported subtype culture and politics. We're separate from each other is only in certain area of the wall and one of this area is right outside West western part of the United States. So here you can see that in
Jin-Yi Yu: California is here, we can see we have one jet stream coming from subtropical region and wanted string coming from the audio isn't
Jin-Yi Yu: An area in most all winter storm follow his politics politics is the one that the rep, the direction of a while Windows Store during wintertime, and the
Jin-Yi Yu: G string coming from subtropical region actually coming from Hawaii. So that's why when this gesturing become subtropical chicken very strong and come to California.
Jin-Yi Yu: Then we call that with a phenomena. Pineapple Express. The reason it is important is because it is going to bring a lot of
Jin-Yi Yu: warm and moist air from tropical region, all the way to California and so
Jin-Yi Yu: And then during those period of time, we will have very, very strong rain for and those rainbow tend to have product to higher temperature. So those stream for won't become a snow, so it is
Jin-Yi Yu: If we window time we have these so called Pineapple Express event coming to California. Now we can continue have green for more than when we are an all the stream for is going to
Jin-Yi Yu: Because you have relatively warm temperature. So, all these ram 404 in a mountain or they still most of is still in the form of water so they become a
Jin-Yi Yu: Fresh fracking come to the fab area, but in the time when we have winter storm when for even having families portraiture stream. And those are the winter storm. Those Winter Storm tend to passing California we have
Jin-Yi Yu: One from coal from structure. So when they come to California. For example, this is California. Let me use the other slide.
Jin-Yi Yu: Is a California when we have podcast stream brain when the storm in this winter storm is has a low pressure
Jin-Yi Yu: And he always come, we will have fun.
Jin-Yi Yu: And co fun structure. So, only this one from income from can produce rainfall. So if we stay in Irvine, then who in this new to
Jin-Yi Yu: The whole front or passing and it is no pressure. Keep on moving, moving, moving. So the cold front we're passing this in one day 123 or four hours. One day or two day so you enjoy it also rainfall event.
Jin-Yi Yu: in Irvine will last one today days three days, but you want us for a long time because these low prices system to keep on moving west for and only those co found, but he passes to
Jin-Yi Yu: Obey your producer and for work when it is the Pineapple Express event that means we have a test Sri Hora testing.
Jin-Yi Yu: Oh no, we have holiday stream shooting all the way to California. Now it's not this politician, we are seeing a subtropical jet stream. And why do you so, so you need because most of time the subtropical gestures.
Jin-Yi Yu: Is the occasion shooting into Mexico and this sub property in a normal situation we're passing through medical and come to come for medical and continue come to south eastern part of United States.
Jin-Yi Yu: And produce all the rainfall here and also rainfall coming to cover medical or come to the southeastern part of of the United States called countless is called goffstown
Jin-Yi Yu: If you're coming from this area. This is called east coast.
Jin-Yi Yu: So those are those are winter stone, but because they'll look they already are the origin of last week windows down the first show up in the cover medical or ON EAST COAST OF A an empty country, someone has a question. I mean, answer that question first.
Jin-Yi Yu: Yeah. Pineapple Express is one form of Risa most of the most critical River. But even when you have these low pressure coming from
Jin-Yi Yu: Is no
Jin-Yi Yu: And this low pressure system bring this home from on fun. They also can appear as atmospheric river okay so Pineapple Express is another form of the autonomous vehicle Riva
Jin-Yi Yu: Event because post this call from and the hypo express bring a lot of moisture coming to California. So when we have waiting for a baby via here.
Jin-Yi Yu: So, as I say, if it is the rainfall event coming from Poland jet stream. Then they tend to
Jin-Yi Yu: last a couple day three days, a few days, never stayed for a long time. But if we for some reason this sub taco gesturing.
Jin-Yi Yu: MBA from his normal location. Instead of hitting medical in particular is winter Mo Mo and also come to California. There's going to be huge amount of moisture come to California.
Jin-Yi Yu: And because this is a question. So when you move to hear you kind of stay here one day, two days three days, four days, five days, six days so it can continue to run as much as more than a week.
Jin-Yi Yu: So, it happened a couple of times a bow tie in Irvine. So, you know, we know that if you have reserved when running event that lasts for
Jin-Yi Yu: Almost a week or longer, but more in a few days, then, is very likely is a Pineapple Express and because this rainfall is coming from writing one area.
Jin-Yi Yu: Rather than whole area in the winter storm coming from is an island. So this is very warm water. So when you come here, even when we have mountain year
Jin-Yi Yu: Sierra Nevada all this rainbow rainbow 40 on this mountain, if it is coming from. Pineapple Express because of the temperature of the water is rotting one, they just rushed to a surface become a
Jin-Yi Yu: Fresh
Jin-Yi Yu: Father.
Jin-Yi Yu: But it is from the Windows don't coming from the polar gesturing. They usually is colder. So quantify this mean for for
Jin-Yi Yu: The Mountain, it becomes now in just stay in the mountain and all these snow in the winter time is going to become a water resource for California during the next summer season. So as you were describing can tell that the location of the porter jet stream and
Jin-Yi Yu: Subtraction stream is very important for California. So you can see if you look at the United State only over the West Coast of the United States. You can see these two separate restroom.
Jin-Yi Yu: And then when they come to the east coast of the United States. They merge each other. Okay, so what it tell you because all the winter storm is foreign either apology Ustream or some
Jin-Yi Yu: Tropical cesarean and then they manage each other over the East Coast and that's why if you pay attention to the TV when I means
Jin-Yi Yu: A winter which here means saying that we are winter storm in this pattern is caused that part is called because his Coast is the location where these two gesturing knowledge to each other in order for winter storm to happen. We need to have low pressure bring up, bring to
Jin-Yi Yu: This particular location.
Jin-Yi Yu: And that's why East Coast has allowed or the winter storm during the wintertime, because they are located in areas where these two gesture much to each other. So when the winter storm is coming from.
Jin-Yi Yu: The production stream here.
Jin-Yi Yu: See, then those
Jin-Yi Yu: gesturing those politics room sometimes will bring this window stone first happen in Canada in moving into a university course the Great Lakes region in come to the New England area.
Jin-Yi Yu: And all those windows does not follow this policy Austrian and begin from Canada we call Alberta creeper. Sometimes this particular stream will more more sauce walk in.
Jin-Yi Yu: The Rocky Mountain, and then this just room will cross these Rocky Mountain and produce a low pressure on the eastern side of Rocky Mountain. That's where we have Colorado. So Rocky Mountains here.
Jin-Yi Yu: And politician coming here and producer low pressure here. So a window. We also very frequently have when no pressure first showing up in Colorado, and then moving across the the
Jin-Yi Yu: central part of the United States and come to New England area. And that's it. We have winter storm coming in this way we call Colorado and if we have a subtropical gesturing coming from medical come to come for medical and then you bring
Jin-Yi Yu: stir stir up capability to another winter storm and those winter storm is called more all the way through the North Eastern United States those stones hole golf stone.
Jin-Yi Yu: And all this subtropical all away come to the east. East Coast and then they will begin to form low pressure right outside east coast.
Jin-Yi Yu: And then we'll move all the way to New England area and then we called our east coast.
Jin-Yi Yu: Sort of cycle form in the United States basically has east or Rocky Mountain means Colorado is a Canadian
Jin-Yi Yu: Rocky Mountain is called alpha a creeper Gulf Coast on the United States territory. Subtract pedestrian East Coast on United States has also due to the sub chocolate chip merge with the polarity have become an East Coast Saigon. And then we have this one that's
Jin-Yi Yu: Coming from Bermuda area and that's for the West Coast of the United States, our windows don't always coming from here urgency and compromise.
Jin-Yi Yu: If we have. We know some rain for coming from here. We call it powerful expressed so now you also based on this map you can tell that
Jin-Yi Yu: The East Coast particularly North Eastern Parliament's. That's why we always hear the word repulsing New York always area has a lot of Windows stop because this is the area where we have these subtropical jet.
Jin-Yi Yu: Merge this the polarity of these tutor mode here. That's why all the Windows Store all the rainfall is going to merge come to this area. So now you understand why the
Jin-Yi Yu: North Eastern part of the United States. Here is the area of a lot of room for us because this politician is some chocolate. Chocolate Rain ABC come to the most eastern part of United States so testing is very important to expand our weather phenomena.
Jin-Yi Yu: OK, so now as soon as we talking about this jet stream structure when then I want to introduce a concept that's called sir moon when parents. Okay.
Jin-Yi Yu: So this one actually already explained last time. The so for those who are not in the physical climate. If you cannot follow this one.
Jin-Yi Yu: You can forgive yourself. So basically summer when patterns is a result of high to static
Jin-Yi Yu: Parents pass another important balance I mentioned God traffic balance.
Jin-Yi Yu: Only going hydrostatic balance and tools traffic patterns are correct, then you can produce summer when parents. Okay so basic idea is the summer embarrassed to tell you that the wind speed change was high.
Jin-Yi Yu: On surface is very small wind speed to brave and strong wind speed.
Jin-Yi Yu: In the upper troposphere. The reason we change with high is because temperature change with latitude, north, south, the right
Jin-Yi Yu: Direction as in I already explained to you last time. And the reason is because when we have temperature change in the north, south, the Russian that equatorial region North Pole region. This is very warm so warm air pressure the quiz, very slowly. So the and then
Jin-Yi Yu: polar region co pilot the quiz very quickly. So this pressure surface for example minibar in its equatorial region because it's a warm air so
Jin-Yi Yu: It will decrease frontline sales a mini path to find to me very slowly with a great taps in the polar region, the pressure truck very quickly. So anytime. When you go to any
Jin-Yi Yu: Arrival aggravation. You always find the equatorial region has higher pressure then all urgency here equatorial region, the project below.
Jin-Yi Yu: Is underneath these find me by so maybe 700 million, but on a per region. The press this high is already above is fine to me or service means pressure is smarter than 500 megabytes or here is maybe 300 million. So it's no pressure here. So we try to produce a win that going from
Jin-Yi Yu: From
Jin-Yi Yu: higher pressure to lower pressure right so I should go north south direction this is V wind instead of here you will use don't know when and why this KNOW SOUNDS temperature on the effect, no cells supposedly only affect knows cells pressure change pp DUI.
Jin-Yi Yu: And how can we can produce on a week. That's because remember whenever you have pressure high and low hear
Jin-Yi Yu: It no sense of direction, then when try to move from
Jin-Yi Yu: One area from here to here, but there's no sauce. When as soon as it would produce no sauce. When the Coriolis for force Association, try to rotate this win by 90 degree become don't know if that's why showing up here. So the heat. That's why we say
Jin-Yi Yu: Summer when parents first has to do with hydrostatic palettes because hydrostatic parents tell you warm air.
Jin-Yi Yu: Temperature temperature is can affect your pressure distribution how pressure change was high read it to be at the y and then how then this the PTC will
Jin-Yi Yu: Affect to strike a balance to affect F Kai's human right, so that's why eventually come to hear. So really, the part of what I do.
Jin-Yi Yu: Is explain, please just forget about it. But for those in the physical crime area. This is the most important comes up. So when I was a graduate student at the University of Washington.
Jin-Yi Yu: And we do the comprehensive exam, every time, Jim. Jim Hogan, which is the also for each most classical textbook for climate of meteorology, dynamic, he always will ask this concept, one of this concept is how do we produce similar patterns. How does every day to hydrostatic and
Jin-Yi Yu: Test traffic. And the other question he huge often us is asked you to derive the
Jin-Yi Yu: dispersing relationship for a raspy way that before last few is it so important concept to expect when the stone balcony way everything in meteorology.
Jin-Yi Yu: Okay, so basically if even if you are not in a fiscal climate research area, you still need to remember
Jin-Yi Yu: That SAML imbalance, tell us that a vertical change or presumably is related to the Latino gradient of temperature right so means wins be changed with high. The reason winspear keep on increasing with high is because we have equator to Pope temperature difference
Jin-Yi Yu: And based on this relationship because in this day. We know our temperature when we go to why from equator to North North Pole, when the
Jin-Yi Yu: Data to increase from zero to 90 temperature truck. So Tim temperature decrease was high increase. So you see this term you sell is negative.
Jin-Yi Yu: And there was another negative sign this whole thing is positive, so it tell you that will be changed with type should be a positive value means wins be will compete with high go up.
Jin-Yi Yu: Increase that was be has to increase in this one explain why we formed the strongest wind near the top of troposphere as where
Jin-Yi Yu: The strong is called gesturing gesturing might usually form above is clean. Clean goes on. So this is the way I just described. So hydrostatic change the producer.
Jin-Yi Yu: Pressure gradient implies you're creating get stronger and stronger or weaker higher and higher. So this pressure gradient is in the north and south.
Jin-Yi Yu: Direction so is supposed to produce we win, but because of geography parents, you will change. It is located. When direction to become east west when
Jin-Yi Yu: So these are explained to us that it will know the temperature distribution, then we can test that direction of the wind. So here for example. Okay, here.
Jin-Yi Yu: This is the temperature distribution. So, it is the equator. This is
Jin-Yi Yu: Not a hemisphere in southern hemisphere, but here we just don't take North and South, which is winter when hemispheres winter. We are a summer. So you can see that in the winter hemisphere.
Jin-Yi Yu: Right. So in this is tropopause trouble Pasco all the way to about 100 amoeba. And then to about one minibar here.
Jin-Yi Yu: This is
Jin-Yi Yu: Stratosphere
Jin-Yi Yu: So you can see that in the troposphere.
Jin-Yi Yu: With a woman's temperature here encode assemblage at a portal region.
Jin-Yi Yu: Their political to the stratosphere, we see that the code is temperature is in the bottom of the stratosphere over the winter.
Jin-Yi Yu: polar region and warmer temperature is along with Apple part of stratosphere right over the summer co already explained last time. Right, so why I mentioned this one again because based on the the
Jin-Yi Yu: Summer when parents, we know the temperature when increased change who how we change with high is proportional to minus temperature radiant with why ourselves. Okay. So, based on this concept of see here, for example, in the troposphere.
Jin-Yi Yu: We have one temperature here cold temperature. So in the troposphere, the TT. Why is temperature gets colder. When we go to higher, why not at you. So this is negative value, negative, negative become positive. So that's why in the stratosphere can see that
Jin-Yi Yu: Is the equator. The wind speed or increase from surface to very, very strong and this one will become more and more positive positive value positive value of you means West anyway. So you can see that
Jin-Yi Yu: Here you can see the brace drunk Westerly when
Jin-Yi Yu: In post
Jin-Yi Yu: Because in the southern hemisphere, the southern hemisphere, the temperature gradient also is similar to Israel in Western Hemisphere that's that's exercise that
Jin-Yi Yu: You can see that amico from minus 90 degree to zero degree. So why supposed to call from minus 92 is, you know, in can see that temperature is
Jin-Yi Yu: Is
Jin-Yi Yu: When we go to the other hemisphere. We need to come see the Coriolis force. So decide what change. Okay. So let's now go to southern hemisphere.
Jin-Yi Yu: Because remember, the CMO imbalance is result of hydro study and to strap, your parents and your software balanced involve the Coriolis or is Tamika which is positive added in the northern hemisphere negative value in the southern hemisphere so that this formula or change so must Napa.
Jin-Yi Yu: matte painting into that one yet.
Jin-Yi Yu: But actually I seem issue. All right. Okay. Let me see. And then so because equator, the pope anytime. If you have one more equator polar
Jin-Yi Yu: polar, polar region, Descartes Westbury when. So the same thing happen in the southern hemisphere woman equator, called a post so you have Sada Western when and then again if you have
Jin-Yi Yu: When we go to stratosphere.
Jin-Yi Yu: Yep.
Jin-Yi Yu: See in the winter hemisphere. Here the coldest temperatures here and woman's temperatures here right so that the t the UI is similar to the troposphere, so they are Walmart equator.
Jin-Yi Yu: Called a pole in the stratosphere. So again, which you observed was the week. So you see here, you kind of West, the will
Jin-Yi Yu: And then we go to southern hemisphere in the stratosphere. We have one Miss temperature at Apollo region colder temperature at the tropical region. So instead of warmer equator cold apart. We have the other way around, we reversed this sign. So we are going to Happy Easter with her so
Jin-Yi Yu: That's why.
Jin-Yi Yu: In the
Jin-Yi Yu: History. These equator north pole, south pole is when then we have Western he when was the winter in the winter time impulse hemisphere in the stratosphere, the chance for me to S3 is in the non anonymous
Jin-Yi Yu: As easily in his Southern Hemisphere. They won't come to summer season on summer holiday July. Again, this is equator. This is
Jin-Yi Yu: Troposphere, stratosphere. Then in the summer time with the jet stream in the troposphere sky study in northern hemisphere was the in the southern hemisphere.
Jin-Yi Yu: But a testing in the stratosphere will change from west to east, the east, the change to
Jin-Yi Yu: Western due to the trend reversal of the temperature distribution in the stratosphere. Can everybody follow this so far.
Jin-Yi Yu: Okay, so this is a little bit combo paper. This is something you definitely need to remember. So you can see that this is 180 many boundaries is equator. So in the troposphere, we have Wesley Wesley read. I mean, positive value and then
Jin-Yi Yu: In here again.
Jin-Yi Yu: In the winter time. So we are variable core temperature here in a struck in the stratosphere, who very warm temperature in the South Pole, so
Jin-Yi Yu: Here the temperature disposition is still warm equator Coco. So we still see
Jin-Yi Yu: Where's the chair. Where's the chair in the southern hemisphere, the warm temperature at the polar rating writing code equator. So instead of West to East Asia.
Jin-Yi Yu: But when we come to the other Caesar this ray Carter was the chief change to east of each year. And this is stage Apollo change to as the chair because the temperature distribution in the stratosphere change.
Jin-Yi Yu: So I want to say about this three sell security, what you should be able to describe about a pressure we have
Jin-Yi Yu: Over 20 minutes and then what happened in us as Apple troposphere about gesture. So now the last thing I want to mention okay because
Jin-Yi Yu: Most recently, I mentioned the user know subtropical high in Sao Paulo in this property apologize, I am holding
Jin-Yi Yu: Okay, no matter you on. Even if you are not working on a physical crime area you will walk in biology or chemistry any area. You need to know those two
Jin-Yi Yu: Knowledge again because you're going to find it very useful to help you to incapacitate your researcher is up, but you have the result you want to explain what happened. You have to thinking about those low pressure high pressure a bad mood or hide.
Jin-Yi Yu: The post passivity. Hi, how it may affect the ring for come to you all the tape you study period climbing, climbing and you go to the Cape to collect data.
Jin-Yi Yu: And space be spiritual. Some and then you need to find a fly in the past five sounding year or 500 a year once a year, you have more room for us or info and then you always have to use the gesture of Pamela. Hi, or use these
Jin-Yi Yu: Alyssa know to explain this your result. Okay, so those are very convenient tool for you to
Jin-Yi Yu: Come up with a story and hypothesis to explain your researchers are even if you are not working on the fiscal come area. So the last thing I wanted to say three to reach three sales encouraging.
Jin-Yi Yu: Is another very important concept need to remember, no matter which research area you woke up because this will give you a very convenient very fluid explain your, your data.
Jin-Yi Yu: So that is we know that we have this three cells occasion. This has happened in each
Jin-Yi Yu: Hemisphere Nona hemisphere has three sale starter hemisphere has analysis resell so totally we have 6667 not I must be one sale to sales Teresa southern hemisphere one sale to sail Teresa. Right. But now as to get the real war as evasion.
Jin-Yi Yu: Okay, so if you look at the UAE, which took took a cosmetologist throughout the whole year without separate them to Caesar your mix winter and summer together, then you see that equator is here.
Jin-Yi Yu: Pretty much you have 123 in a row hemisphere 123 solid mysteries a symmetric. But now if you look at consider season as a non me Maura
Jin-Yi Yu: So you actually sell right and then again you have but you Lucy that you even do it at the differences are not square. It is become exciting.
Jin-Yi Yu: If we are no mean that means you assuming the strongest sunlight Cheyenne equator, then you have had resale here.
Jin-Yi Yu: In a non MSP a fire sale policy or you have another harvest in southern hemisphere and because of the call, you know, schools are
Jin-Yi Yu: on opposite sides, we can see positive very here is up and down, you know, hemisphere in southern hemisphere negative value is up and down. Correct.
Jin-Yi Yu: But now interesting scene is now if you move this maxima sunlight earning a bit off from equipment for example instead at God, we just move it to two equally see only particular arena. A sunshine move into non MSP so he's become summer.
Jin-Yi Yu: Look at, is this how to resell in northern hemisphere. When we move the sunlight into northern hemisphere, the. How do you sell enormous it becomes weaker.
Jin-Yi Yu: In the heart. And so in this window hemisphere become strong
Jin-Yi Yu: You know, our sunlight even more to enter into a sub northern hemisphere. So no have spear become summer you see that on you know to 60 degree. The hotness in a more
Jin-Yi Yu: In the winter hemisphere in the southern hemisphere disappear. We only has one half Lisa shooting into the when the hemisphere. Okay, so this is something that
Jin-Yi Yu: Which have been some discovery in the 1980s. This is one of the most critical paper about is how do we sell because it tells us that this research circulation can
Jin-Yi Yu: This how the resale particular is happening, still have the sale always rise at it's summer hemisphere in cause equator shooting into winter hemisphere. Okay. So why is this important because, I mean, explain each speaker first. So here you can see
Jin-Yi Yu: This is say it's a non MSP some see the only one with them. See how to sell me this one become very weak, we only see one big hobbies arise at IPCC
Jin-Yi Yu: The pathetic winos airlines and cross the equator going to southern hemisphere coming back. Okay. So instead, or Happy, happy cell by cell in northern hemisphere in by saying Sala MSP without crossing the equator. Now we
Jin-Yi Yu: Allow indifference different season when he says summer some water, some I mean means a lot of sunlight. Right, very well.
Jin-Yi Yu: Then nature, say I don't want to make one hemisphere very well the other hemisphere. Very cool. So nature decide equal to produce a heavily sale cross
Jin-Yi Yu: Be equal equator from one hemisphere to the other. A always coming from one summer hemisphere imprint energy into the coffee, where the code for the winter hemisphere so happily sale.
Jin-Yi Yu: Is very strong
Jin-Yi Yu: Only in this
Jin-Yi Yu: Summer MSP so if you so for example in will now study something you collect data in enough in California.
Jin-Yi Yu: Right and you discover data that has up and down, up and down in the past five years. When you say how do I explain this is I'm going to use half of the sale. So he said, No, we're collecting
Jin-Yi Yu: The info data. I was some low temperature in Arizona in the past 500 years and I finally up and down, up and down some yes Johnson. We then the reason is because in that
Jin-Yi Yu: In the summer over Arizona. The temperature is is Ariana is in the silicon range of the have a sale. So when hot is simply a stronger Arizona temperature a warmer in the auto 100 years when hobbies do is
Jin-Yi Yu: Is typically we could indeed the other 100 years then the temperature in Arizona is the last one. That's why in the past five years, Arizona summer temperature
Jin-Yi Yu: June, July, August, temperature, up and down, up and down and use some of these paper to scientific journal a webinar reviewer. I'm going to say, you are wrong.
Jin-Yi Yu: Why you are wrong because you're analyzing temperature in northern hemisphere during the summertime and you try to use half of the sale to explain the phenomena you observe, but I'm going to challenging you, because
Jin-Yi Yu: My Chinese and in his car decal people already tell us during the summertime half of the sale is very weak.
Jin-Yi Yu: In Northern Hemisphere. How did he sell always drunk in the winter hemisphere. OK, so now unless we read through the story. If you are collecting data in our in Arizona and you try to find out the
Jin-Yi Yu: Surface temperature in Arizona during PJ in the winter time. And in the past foundry year that when the temperature in Ariana go up and down, up and down the US to write a paper say or
Jin-Yi Yu: Reason that the climate change in the past foundry year in Arizona is because the temperature there reflect the change of hardly sale.
Jin-Yi Yu: In the past, find a year, then I'm going to say, you are probably right because you're explaining winter phenomena.
Jin-Yi Yu: This is the season that have received in the northern hemisphere is struck. So I'm going to take your explanation. So everybody follow the reason I mentioned this one because
Jin-Yi Yu: You have to remember heartening sales were struck only in the winter hemisphere. Again, if you want to use policy or to any explanation of your resume measure your female Amina that you can Emily, you try to explain happen in the winter hemisphere.
Jin-Yi Yu: OK, so I'm going to
Jin-Yi Yu: Please, someone remind me on to talk about the mitten. So everything I say so far is so called the zonal
Jin-Yi Yu: Means security in general security. Okay, and last while we come out with this picture of the three sales situation 123 and half a selling wholesale
Jin-Yi Yu: Very strong and is faster is very weak. The reason is, is because in this multi modality region this zone, no mean general security is not in order
Jin-Yi Yu: In a meter Lafferty region we have temperature change very quickly. We start at you and you will produce allowed or train engine at activity. So this gentleman.
Jin-Yi Yu: New of circulation, the meat of it is nine both and that's why we need to introduce the concept that we call changing at all trying to add is you can consider one is x coordinate general circulation. The other is called y coordinate Trajan ad. So they are two different part of
Jin-Yi Yu: Mansion in atmosphere that to pray the difference. Oh, and seems an energy Perez.
Jin-Yi Yu: So now let me talk about what is the change in AD. Okay. So when we talk about the three says occasion we are considering don't know. Ah, and time. Ah. OK, so my average we use this pack pack basket.
Jin-Yi Yu: To recreate that timing temperature average we use this over back whenever you see the basket.
Jin-Yi Yu: Then last the domain where you see over power loss of timing. Okay. And this social security is who is on the air which everything in the acceleration is weapons.
Jin-Yi Yu: Restoration we average so many, many years or so don't know and temporary and whenever is not explained by this internal and temporal a which is called trying to add
Jin-Yi Yu: And this is called participation and this trend in any they are different seems okay usually agree paper to say the trying soon a the
Jin-Yi Yu: Order. Some nights I say the ad because besides changing at we have something called stationary ad whenever we say ad means it is not a tsunami instead of a circle, same area is going to produce
Jin-Yi Yu: Up and down vital high know. I know. So a whole circle. So the ad means that deviation from the zone army and Transient means that those
Jin-Yi Yu: variation that is not included in temporary outage. So it has a deviation from a temporary which, for example, we see that after the long on average, we always see
Jin-Yi Yu: I also know here, but in the winter time because I used to know is very strong winter time. So after would average for non own time, we know
Jin-Yi Yu: Industry sales occasion near this area to 62 winners on the surface, we should produce a supporter low and support location know crappy. But if you look at, for example, this year, nice Apollo, maybe this is no maybe okay here and two years ago, the
Jin-Yi Yu: Audience I know maybe located here. So you have to erase some variation, whenever the variation that's different from the commonality is called Treasure.
Jin-Yi Yu: So now we need to we need to talk about this. Okay, this is it. Because everything we talked about motion. Why do we need to emotion in Otter must be an ocean.
Jin-Yi Yu: The reason is because we have a lot of sunlight at a polar rich equatorial regions so very warm and portal region. We do not have enough sun. Very cool. So we need to produce motion to bring
Jin-Yi Yu: Energy from equator to PO. So that means we need to produce motion V and then is Carrie temperature. And this has to be positive.
Jin-Yi Yu: And means we are bringing energy from equator to Pope, he says, y coordinate the 01 Kentuckian also why increased to two polar region. So we try to produce this template this sheet.
Jin-Yi Yu: Know South motion for in temperature, we try to make it equator and 02 parents that and we realize that all this notion in our atmosphere is not only this general circulation story so security we also
Jin-Yi Yu: Have a treasure ad. Okay, that's not including industry serves occasion for example winter. Stop. Okay, so if we do that, we say, okay, all the
Jin-Yi Yu: Temperature v can be suffering into the timing price, the deviation from timing deviation from timing means transient right and then timing.
Jin-Yi Yu: The timing can further supper into timing in Soma average and timing, not in don't ever he was at, okay, this is called stationary ad and whatever love over
Jin-Yi Yu: Does not including in timing or not, including and all army is called changing it. And then you do the same thing for temperature and you put this V into this term to put it into a standard expanded to become this hosting
Jin-Yi Yu: seems really complicated, but the king.
Jin-Yi Yu: Point is trying to tell you that
Jin-Yi Yu: We try to bring temperature for equator, the Pope.
Jin-Yi Yu: And this mission is accomplished by for a street different things. Mathematically expansion or give you a 3D printing and then the first thing is
Jin-Yi Yu: The wind and temperature average unkind and in moderation. This is called general circulation. And so how do we sell for our South Paulo sale and this one which is not this is deviation from time
Jin-Yi Yu: Deviation from time
Jin-Yi Yu: And this is something called
Jin-Yi Yu: Changing
Jin-Yi Yu: Ad
Jin-Yi Yu: And this one is deviation from the norm in but it's a bridge this wind and temperature distribution doesn't change with time, but its structure.
Jin-Yi Yu: Very in the east west direction is called stationary ad
Jin-Yi Yu: So anybody means
Jin-Yi Yu: Something that go up and down, up and down. And so no direction nose up and that can be not changed. We stand up can be changed with time. It's called Treasure an ad. So I think this is really complicated. But let me show you.
Jin-Yi Yu: Sort of toggle he transport can be carried by mean for which is three sales acceleration
Jin-Yi Yu: Harry by stationary ad hoc query by changing at. Okay. So, can it can be satisfied to find out which time is important to to bring the temperature from the equator to polar region. Okay, so we realize that in a meter, the region that we mentioned last time.
Jin-Yi Yu: The village equator po po
Jin-Yi Yu: Atmosphere transport our energy somewhere around 30 the green lawns and 60
Jin-Yi Yu: Nose and most of this is Carrie.
Jin-Yi Yu: Have by stationary have by changing it. So what is the example of stationary at this is for example this jet stream as well number one number two or number three.
Jin-Yi Yu: They don't change which time in the wintertime. They always look at is look at ease, and they will print temperature from home equator two polar region.
Jin-Yi Yu: And this is called stationary so station ID result from East West variations service innovation and service temperature contrast between continent and ocean.
Jin-Yi Yu: Stationary the largest in the northern hemisphere Himalayan Rocky Mountain provide
Jin-Yi Yu: Produce all the stationery store stationery. You need to have a big mountain and see the in contrast to produce stationary already
Jin-Yi Yu: Because Southern Hemisphere. We do not have a lot of land and we do not be mountain so station ID in southern hemisphere is very weak.
Jin-Yi Yu: But we have something called changing at look at here because you can see that is high and no pressure to keep on moving from
Jin-Yi Yu: Yesterday, we're now a three hour call three or later. So they're structured Cuba moving in these previously. This one, this jet stream subtropical Cipro
Jin-Yi Yu: Politic they are structured does not change. That's why the reason cause a Peace Corps, see here this is a 630 degrees that little circle.
Jin-Yi Yu: We see that the structure is in this circle is up below. Up and down, up and down, instead of just ones that we go up and down as quad core ad, but you never change with time as core core stationary at and this is at. You can see that in the
Jin-Yi Yu: One that you you have high pressure low pressure, high, low, high, low, high school basketball coach at and you can see that here took a time this is
Jin-Yi Yu: 10am 10pm 7pm 10pm to 3am just is ABC our, you can see that is no pressure neighbors staying in certain location as far as moving. That's called changing at
Jin-Yi Yu: Who are is changing at least equal to recall when to stop. So this is very important change in AD soco is rapidly developing and decaying or
Jin-Yi Yu: High and low pressure, they generally move from east to west, because it is true and subtropical temperature
Jin-Yi Yu: These disturbance are very apparent and where I'm at and have typical period of a life cycle, a few days a week.
Jin-Yi Yu: And so those are one is going to bring a lot of heat from Mila service. So, this
Jin-Yi Yu: Change in AD or try to really hear from equator to Pope in the metadata region, but a station at the amateur Cadbury with large in Apple troposphere. That's why they are responsible to transfer
Jin-Yi Yu: Energy from equator to Pope in the upper troposphere and change in AD transported clean polo was near the surface. Okay, so I want to say about
Jin-Yi Yu: This and then we'll also talk about when these energy can transport from equator, the PO besides green temperature, it can bring energy in many
Jin-Yi Yu: Separate several different other pop formula besides sense, for he has a temperature you all can always can also bring energy portal in the entire
Jin-Yi Yu: Time.
Jin-Yi Yu: Everybody still with me.
Jin-Yi Yu: Well,
That's
Jin-Yi Yu: Good.
Jin-Yi Yu: Location for this tonight's lecture. So I want to mention. I'm not sure that internet. Okay, so here I only have
Jin-Yi Yu: I don't think I'm going to ask you this question in the, in the meantime, so I'm going to stop here and then naturally will quickly finish these
Jin-Yi Yu: Are the rest of these atmospheric or chapter because not missing. I need to say only the main thing is this winter storm concept of a very quickly and the concept of energy trans trans, put it in our atmosphere can occur in several different format. Okay, and last call the
Jin-Yi Yu: Noise static energy and this thing is not new. This has become very, very has research subject so you very high possibility that all of us going to read the paper than people mentioned is concerned. So even though in this next
Jin-Yi Yu: One, as mentioned called come to this chapter. I'm going to only briefly talk about my static energy concept but
Jin-Yi Yu: You need to pay the page into this concept because it's become a very powerful way to thinking about climate change in a lab or climate change paper in recent past few to
Jin-Yi Yu: About 10 year alone of paper is going to mention those concepts you need to measure, you can get scared by all this terminology. Okay, now let me stop here and come to
Jin-Yi Yu: The meeting. So I'm going to ask everybody come to the meetup Thursday court order Room meeting and then you're going to embody corner. Please turn on your camera. I'll talk to the department.
Jin-Yi Yu: Some of our faculty member and try to find out what's the best way to this online because I cannot do this open book. I'm going to do a crossbow so Tuesday, Thursday. Everybody come to this room meeting at a sign era is actually the same time 11am and then turn on your
Jin-Yi Yu: Camera and come to the midterm on canvas and then answer. They are going to be 40 multiple choice question in about two or three free answer question. So one free answer questions very straightforward just write down this
Jin-Yi Yu: Buddy called cross session structure automatically encoding the high pressure value of the troposphere Charles fear.
Jin-Yi Yu: And who is the warm temperature, temperature, we still when wrestling. I believe everybody needs to have a nice concept.
Jin-Yi Yu: And then, of course, the other one is commonly asked is related to how to a static patterns and then press another 14 multiple choice.
Jin-Yi Yu: So it's going to be karma from the first lecture, all the way to today's lecture at the most critical chapter security in Chapter knows my steady energy and
Jin-Yi Yu: A balcony away. I didn't mention yet you do not need to prepare those part so prepare everything we have so far and just read a PowerPoint.
Jin-Yi Yu: On nine and then come to a room meeting next Thursday. I will send me the email to remind you again. The Room meeting location, the same as today's and then just remember to turn on your camera. And the other question. Anybody for the meter.
Jin-Yi Yu: Know,
Melisa Perut: I have a question will include any calculations doing it to bring like a calculator or anything like that.
Jin-Yi Yu: Or you pop it to need to have a
Jin-Yi Yu: Calculator for the calculation should be very simple. Yeah.
Jin-Yi Yu: For free for years, a question you need to have a calculator.
Jin-Yi Yu: Any other question. You ready to meet them.
Jin-Yi Yu: Now, okay, so I will see you Thursday for the meantime. So I know we do not, we have to steal them not coming missing. And then in case that
Jin-Yi Yu: Who, no one is, did anyone know who didn't open the lecture because I need to send them a reminder
Jin-Yi Yu: Oh, I remember you can have a
Jin-Yi Yu: Social media something for this whole cast. I'm going to send an email to everybody. Yeah, so make sure everybody will come to the room. We will nurture answers that. OK, that's it. Thank you very much. I will see you on Thursday for the meter or goodbye everybody
