Jin-Yi Yu: For some reason, some of you can come into the room meeting directory for some of you need my permission, Madam me require me to do something to carry on. Yeah. And it'll pick up a daughter in the following lecture.
Jin-Yi Yu: Okay, so wait for one more minute. See if anyone's coming
Jin-Yi Yu: So, haha. Yes. So since I need to real all of us men this afternoon, but a common come back even me. I just tried to read your name right now and what you preach
Jin-Yi Yu: And you struck me how to pronounce your name correctly.
Jin-Yi Yu: The first one is
Jin-Yi Yu: A Copa
Jin-Yi Yu: Say, how do I say your last name.
Ada Acobta: A copter.
Jin-Yi Yu: A Copa a Coke.
Jin-Yi Yu: Coke. Can you think of image and then we got a radius. And it's a Welsh. How did you pronounce your last name. Sorry buddy. That's correct.
Jin-Yi Yu: I cannot hear you. Could you
Jin-Yi Yu: unmute yourself, please.
Allison Welch: Sorry, I
Allison Welch: Yeah, it took me a second to find my window. Um, yeah. Allison lunch. That's right.
Jin-Yi Yu: Coach much. Okay, thank you. And then, is anything
Jin-Yi Yu: Then who's Brian Paul is is it as an input.
Bryant Pahl: Yeah, it's Paul
Jin-Yi Yu: Okay, well, I keep on switching on the screams I mean either Kobe now is I met him endo bio cheese.
Jin-Yi Yu: I'm in the middle between the how to say his name is
Armando Vilchez: Joe chess.
Jin-Yi Yu: Chess okay and is Brian port. Could you say that again, Brian. Sorry.
Bryant Pahl: Paul
Jin-Yi Yu: Just okay
Jin-Yi Yu: Anything and a camera camera.
Jin-Yi Yu: Okay.
Jin-Yi Yu: And then, Jennifer.
Jin-Yi Yu: Compose
Jennifer Campos Ayala: Okay, yeah.
Jin-Yi Yu: So that's an ICO who is a compass.
Jennifer Campos Ayala: Can either it's two last names book impulses, fine.
Jin-Yi Yu: Okay. Okay, thank you. And then
Jin-Yi Yu: Jerry Dean one Polanco and then Kyle many
Jin-Yi Yu: If I pronounce Ron. Ron, please just unmute your microphone and let me know and Lucas. Lucas, I don't know. You're asking idea is you're asking manuscript.
Lucas: Dos
Jin-Yi Yu: Santos. Okay. And then we say I miss anyone
Jin-Yi Yu: Nicholas fun them.
Jin-Yi Yu: But some of you are not yours as major, then you can test the economic my
Jin-Yi Yu: My practice here.
Jin-Yi Yu: Nicholas
Nicholas Pham: Hi there.
Jin-Yi Yu: How did you pronounce your last name.
Nicholas Pham: fam. It doesn't matter.
Jin-Yi Yu: Fan. Okay. Nicholas. Thank you. And let me see the icon to everybody.
Jin-Yi Yu: And then is a
Jin-Yi Yu: Pair of
Jin-Yi Yu: Minnesota's
Melisa Perut: Hi, it's me. Lisa pedal.
Jin-Yi Yu: Pedal, pedal, pedal. Okay, thank you.
Jin-Yi Yu: Skyler. Skyler.
Jin-Yi Yu: Skyler help
Jin-Yi Yu: Him, please.
Skylar Dominic Gerace: Curious
Skylar Dominic Gerace: It's like a soft G.
Jin-Yi Yu: Could you say either
Skylar Dominic Gerace: Juries
Jin-Yi Yu: Jury. Okay, thank you.
Jin-Yi Yu: Nice Stephanie.
Jin-Yi Yu: Any other
Stephanie Grace Stettz: Last Name is stats.
Jin-Yi Yu: Stats. Okay, thank you. And then
Jin-Yi Yu: Sweat. I need your help on he's on
Swetha Cherukuri: His chair curry.
Jin-Yi Yu: hobo the first name.
Swetha Cherukuri: As what you gotta write it
Jin-Yi Yu: In the last name is
Swetha Cherukuri: Chery
Jin-Yi Yu: Chery curry. Okay, thank you. And that boat.
Yeah.
Jin-Yi Yu: Perfect.
Jin-Yi Yu: Okay, and Utah and then yeah. Okay. Okay. Thank you, everybody. Sorry to take your town this one. Okay, let me
Jin-Yi Yu: Hi.
Jin-Yi Yu: I didn't share the right screen and please just unmute the microphone, tell me that you are looking at a PowerPoint or something. Okay. So, last call this our first lecture which title.
Jin-Yi Yu: Which title.
Jin-Yi Yu: Which title on me and now my screen. Okay, which try to describe the autonomous vehicle property because this is the first major component our system. I mean us climate system.
Jin-Yi Yu: And I was talking about. The first thing we need to know is what kind of atmosphere we have and
Jin-Yi Yu: What kind of animals we have is referring to what kind of guess so, meaning how atmosphere or a rated really actually very active.
Jin-Yi Yu: Or not active. So for all for all other must fear the major component of the guys is nitrogen, oxygen and our GM and then we know that our own three guesses. They're not
Jin-Yi Yu: Active in the IDF the way I mean they don't interfere with the ideation process. Either the somebody comes in to our system or ideation goes out to try to cool down our kindnesses that these are the engine coming in from the sun. And let me switch my
Jin-Yi Yu: Okay, so when the sunlight coming into our current system. This is usually at the shelter where brands. So we're going to discard is more detail later.
Jin-Yi Yu: But first have to remember in climate science whenever we say solar radiation we somehow also call it short wave radiation, because the
Jin-Yi Yu: Radiation come from Sam has a very, very short wave Vince. The shorter the weapons, the stronger the radiation and the radiation escape from our climate ERS to cool down our climate is called terrestrial radiation.
Jin-Yi Yu: And those radiation usually operate a longer wavelength casali call normally radiation. So when we say short way radiation.
Jin-Yi Yu: Now means solar radiation, always a long way radiation means the terrestrial radiation such a cool down our cell and low these two component radiation determine our climate temperature, temperature. That's why when we talk about global warming climate change, we need to sink in.
Jin-Yi Yu: Orange first in the first place when you're singing about how much radio show or the Asian come in to heat up are coming
Jin-Yi Yu: How much aloma radiation escape from our climate cool them archiving and the balance between these heating and warming is going to determine our global temperature to accomplish in the next two chapter but
Jin-Yi Yu: We want to know when we have atmosphere and any premise, we need to know what kind of cash they have and are those major cast very can interfere with the show away or long way on that.
Jin-Yi Yu: Anytime now in our atmosphere Earth's atmosphere. The major guess, nitrogen, oxygen in Africa, they do not interfere with our show away and only radiation for why
Jin-Yi Yu: They don't interfere with our radiation, there's a reason for that, which will describe. But basically, in order for any cast to affect to absorb radiation either show way along with those gases.
Jin-Yi Yu: They have to have certain energy level associated with their molecular structure. So, and it cannot, for example, oxygen, all to
Jin-Yi Yu: Their as their more Oculus structure if they want to change from one energy level two second energy level to the sir energy that post level three level four, the energy difference between they don't worry about too is how much energy they
Jin-Yi Yu: Need to absorb from radiation in order to jump from one any energy level to the other and
Jin-Yi Yu: Because we know that energy, Dave, how much energy can be carried by radiation is something to do with a constant times is frequency which is one over weapons.
Jin-Yi Yu: That means the energy carried by any radiation is a constant is a proportional to is frequency or inversely proportional to the wavelengths of God radiation. So if we have these four lie.
Jin-Yi Yu: If we have
Jin-Yi Yu: Ultraviolet radiation. We have or is that
Jin-Yi Yu: Don't go wherever we find out all the solar radiation come come from Santo Earth. Most of this radiation is concentrate on this paradigm and all these be supported their weapons are so small.
Jin-Yi Yu: Showing then none of this guess not. So, not this one doesn't match if you kind of this webinar is over one times a constant to find out is the
Jin-Yi Yu: Energy carry we find out that the energy carried by any visible light. Most of them sort of the nation does not match the energy that the difference between energy level.
Jin-Yi Yu: Associated with associate associate which is nitrogen. A Sonia. So that's what sort of the issue when it comes to how those are the most fear. Nobody can absorb it, because the among the energy carry does not match any of these major cast energy level even Yuko CO2.
Jin-Yi Yu: Helium already smoke. So if they do not can now utilize they cannot use or the solar radiation. But when when the radiation escape from Earth. The tourists are the aging trying to go out all these are long way. They tend to operate.
Jin-Yi Yu: On this very long way plans because it up right and wrong weapons we find out that some of these cases copper oxide.
Jin-Yi Yu: Those the wavelengths of this particular region happening the energy
Jin-Yi Yu: The energy carry happen to match the energy level for carbon dioxide for mapping for match oxide for all. That's why all these cases, they can absorb all these Teresa radiation. And that's why they become greenhouse gases. Okay, I come to this point.
Jin-Yi Yu: Data. So basically,
Jin-Yi Yu: That's why we need to not a composition of other must be if we whenever we studied any pregnant. We need to know what kind of bucket must be a yes.
Jin-Yi Yu: Okay, so now, that's why. So try to emphasize, baby. How you coach lecture a call to a chapter in the textbook, you have to ask yourself why
Jin-Yi Yu: The also want to discuss this subject, what is the importance of this subject to the area of use the science you study
Jin-Yi Yu: And then second thing you want to ask yourself why the author, the author or the the chapter or section in a certain way. Right. I mean, the awesome. So the whole picture about a concept.
Jin-Yi Yu: He or she on the river forest Greta and that's why he's been you need to know. Chapter one on Samson first and then in order to describe chapter to chapter three. Okay. So whenever you read anything, ask yourself why
Jin-Yi Yu: The also want to talk about it and why in this certain order. So now let's come back to this. The reason I mention that is because you asked yourself why one would know the composition
Jin-Yi Yu: Of our most fear because based on the composition of outermost feel we can find out
Jin-Yi Yu: How much this radiation comes in to our climate system, how much you really can cause out of our climate system can be interfere by our atmosphere that sort of conclusion is the
Jin-Yi Yu: All this percentage 78% plus 20% plus almost 9090 something percent of our own Otter must fear the guest does not interfere
Jin-Yi Yu: Our radiation process, so they are not important for coming by those small percentage, they're
Jin-Yi Yu: Not over only 0.04% of the mass in our atmosphere are the guest most important to Moderate. Moderate to order to change the control the temperature of alchemy. OK. So now we'll go. Most of this
Jin-Yi Yu: Class is going to focus on this 0.04% of how atmospheric guests for order climate study understanding but still we want to know, how can we have such kind of other must be with so many nitrogen, oxygen and Agha yeah that's the next slide, I want to show
Jin-Yi Yu: And this is the one is consider is the first story. We have to be able to tell general public.
Jin-Yi Yu: If we go to any car so to talk about climate change, then we say we have such kind of atmosphere surrounding cover on our surface and then why we have such a
Jin-Yi Yu: Kind of atmosphere because by understanding the origin of our Earth's atmosphere. You can apply the same concept to compare why mass temperature is so co Venus temperature or Jupiter climate is so what because the same argument you can
Jin-Yi Yu: Buy you can practice the same thinking about what's the origin of atmosphere for mass
Jin-Yi Yu: Or for your opinion. Okay, so now let's practice this sinking for our Earth, but I must feel. So the question is why we have such kind of competition in autumn Austria.
Jin-Yi Yu: And the textbook telling them that they are two parts possible or region for any other must fear and any pregnant the first
Jin-Yi Yu: Principle is becoming the other monster.
Jin-Yi Yu: Composition is depends on what happened when the premise was fun. Okay, so here we sent when the earth was was formed about 5 billion years ago.
Jin-Yi Yu: As a chemistry was property. Most of the hydrogen Hadean and process, hydrogen, hydrogen compound. All those are very, very light guess
Jin-Yi Yu: They are very light. So they are easy them. They can isolate whenever the temperature, they can actually move around very quickly. Very quickly.
Jin-Yi Yu: They have a lot of kinetic energy sort of gravity cannot hold them all the time, close to service. So most of these initial cast is not when ours was fun.
Jin-Yi Yu: All these like so eventually escape to space. So they no longer stay in our commencement. So, this process is not the main reason to determine how autonomous vehicle composition
Jin-Yi Yu: And the second mechanism to determine the composition of any planning on any other material any premiere is the release of gas from volcano eruption. And this process is called outgassing this release against from volcano is Caucasian. This is the key process.
Jin-Yi Yu: To determine what kind of composition. The outermost BASED ON THE HALF HOUR WE'RE GOING TO FIND OUT AFTER THIS OUT guess Asian process, we need to invoke involve some our process to determine the final composition
Jin-Yi Yu: Okay, so the conclusion the cinema emphasize here is our other monster composition is determined by to process how guessing this is major one and then will produce a lot of gases which is carbon
Jin-Yi Yu: Which is when we have volcano activity McKenna is going to inject three key gases into my spiel before everybody can guess, of course, carbon dioxide.
Jin-Yi Yu: I want to put this in first.
Jin-Yi Yu: Change it for their
Jin-Yi Yu: Own to put water vapor first
Jin-Yi Yu: Is the reason I want to put this one first and then I want to put carbon dioxide. Second, and the circus is nitrogen.
Jin-Yi Yu: So we know that when there's a volcano eruption is going to inject three key three kind of gases water vapor, carbon
Jin-Yi Yu: And nitrogen, but we know that the final composition of atmosphere is nitrogen, oxygen and outcome. Right. So among all these three cans of the query in check, or release. Bye.
Jin-Yi Yu: Volcano only natural thing to interface or thermosphere water vapor disappear. Does it wish there was a paper but sinking by eval. Oh, Earth, keep on producing in Volcano injunction ingestion injection as water vapor, carbon dioxide.
Jin-Yi Yu: And nitrogen. Then after five periods of ears or volcano activity, almost as you have a lot of water vapor around a common answer around. Oh, nitrogen, but it turned out that water vapor now just a small amount of guests here on the 0.02% and then
Jin-Yi Yu: Carbon dioxide is only 0.035% of our chemistry. And how come they cannot water vapor cannot stay in the thermosphere carbon dioxide cannot say enough, I must be a master last day, the power of story. Want to
Jin-Yi Yu: Talk about in this by telling the story by explaining what happened to water vapor, we're going to introduce a very, very important concern.
Jin-Yi Yu: That is so important that very important for our present a study of climate change, global warming. Okay, so what is this concept.
Jin-Yi Yu: This concise, or even though volcano, keep an eruption eruption produce carbon water Baker producing carbon dioxide, but whatever. So he became Akiba injection for five years. Right. But how are the most fear so but cannot keep them in check. Water vapor water, but one of a
Jin-Yi Yu: Lot of women and after the fight the enemy, and we should have another
Jin-Yi Yu: Another one way, but he cannot know we only have very small percentage of water, but in the atmosphere. What is the reason is that these centers, the atmosphere can only hold small fraction of mass of water vapor that has been injected into that I must have a tearing volcano.
Jin-Yi Yu: Eruption and most or one of them has been convincing into a cow and become ocean see 97% are water vapor in Alchemy system 90% of water in our current system is now in the ocean 2.4% is glacial ice.
Jin-Yi Yu: Over unhappy in Greenland, and then groundwater the OH 6% and other must be only holds 0.001% water in our climate system. So always ingestion or to determine what have a server came up eventually cannot stay in most fear information.
Jin-Yi Yu: From atmosphere. So we have water vapor here. So anybody. What is that process to make water for them from sky to surface. When is a process called anyone
Jin-Yi Yu: Is called priests potential rent for right so everybody sing NASA very straightforward sinking and of course if you keep them in check. Water vapor into a coma sphere.
Jin-Yi Yu: But at the monster is condo become what what is up preclinical disquiet water vapor what happened the Rhine River in order to produce to make water vapor contest become room for one is up walking, could anybody just
Jin-Yi Yu: A meal. Your microphone and speaker because are difficult to reach
Ved Bhoot: Saturation.
Jin-Yi Yu: Saturation. That's the key war.
Jin-Yi Yu: What does the saturation means
Jin-Yi Yu: When we have an air.
Jin-Yi Yu: And we say,
Jin-Yi Yu: Is reach saturation
Jin-Yi Yu: We have air box over here inside and we say water vapor inside apart reach saturation. What does that mean,
Jin-Yi Yu: The amount of water vapor inside this box is already reached the maximum capacity that air can hope, right. So what does that mean i mean there is a physical
Jin-Yi Yu: control how much water vapor any air can hold a cannot hold a name is Amanda water vapor and air cannot decide how much water vapor. It can help by cell.
Jin-Yi Yu: There's a field called our control. That's why all or my cooking here is try to bring you to that physical for either physical or call anybody if you happen to know that what is a physical becoming the amount of water vapor amount of air and water. We
Jin-Yi Yu: Can hope.
Jin-Yi Yu: Became was a C.
Ved Bhoot: Class classes copper. Copper honor. Yes.
Jin-Yi Yu: That's the one of the
Jin-Yi Yu: Name or equation how long you to memorize it. Okay. Because even you are not doing physical climate in your research on in the future.
Jin-Yi Yu: You still want to be able to pronounce this time out of your mouth when you say
Jin-Yi Yu: tell people about what happened to alchemy sister. You tell people how come it's getting warmer and warmer and then you went to not do anything we keep on finding
Jin-Yi Yu: The driving car and really as common as I even if we release the same amount of carbon dioxide 20 years later.
Jin-Yi Yu: The Mandel comment as already released today now model happened as a release from human being is not changing event. That's the true, but the same amount of
Jin-Yi Yu: Coverage as I release is going to cause a stronger or natural woman in the future. And the reason for that is because of these classes Crapper on equation. I'm going to try to motorcycle.
Jin-Yi Yu: Here.
Jin-Yi Yu: So everybody see the slide classes capital.
Jin-Yi Yu: Equation. So, this equation is the most money equation, but a key part is not a must magic formula to Cuba is you have to remember this name because the brain important for climate change and global warming.
Jin-Yi Yu: Discussion. So what does this equation tell you or the retention period. So we are not going to cause red. I'm going to just deliver one thing he tell you that how much
Jin-Yi Yu: The saturation water vapor a month. So forget about pressure. This is equal to among
Jin-Yi Yu: So, this equation here, are you based on this physical must mother equation how much demons change how much the amount water vapor change so means
Jin-Yi Yu: As means to saturate the maximum amount of water vapor in the air can whole
Jin-Yi Yu: Is come to all this, see the Amanda water vapor. The Century among us, the saturated model. One of the vapor a can. Whoa.
Jin-Yi Yu: Is controlled by this formula. The Rhine from this process copper on equation.
Jin-Yi Yu: And all these expressions tell you the maximum on water vapor air can haul is controlled by this complicated equation. However, looking is what is 6.11 constant that's broken up by Al is how much they the heat release right by water which is a constant as forget about
Jin-Yi Yu: The is a cast comes to read into water vapor that's popular is a constant, forget about one over to Sir ministry.
Jin-Yi Yu: Is Kirsten TALKING ABOUT THE ONLY THING CAN CHANGE relate to our a property you have air in the morning 9am and in the air over by the upload PM. This to add on inside this whole equation this morning or afternoon or my an amazing difference between them is the temperature
Jin-Yi Yu: And this causes copper in question tell you in the early morning oh my air can hope more or less water vapor compared to the afternoon my air.
Jin-Yi Yu: Air is only determined by the temperature difference between morning and afternoon because the physics, the nature tell you the only thing determine how much water vapor an air can hope is only one thing the temperature
Jin-Yi Yu: Of the air. Okay, so if we have a warmer air in the morning in Irvine. Oh, nice air morning air can hold my water vapor or less water vapor compared to afternoon it morning is warmer.
Jin-Yi Yu: In afternoon is called opposite, opposite from what we are seeing it. But if he has warmer temperature be as a colder temperature than a end can hold more water vapor
Jin-Yi Yu: That's very, very important concept, why we care about how much water vapor. An aircon whoa okay let me tell you quickly the tourism, we care about that. Okay. First reason. Let me switch to a slide as a more white space, I can. Can I say
Jin-Yi Yu: Okay, how much Amanda
Jin-Yi Yu: How much water. Water vapor a can. Oh, okay. That's great. That's cool.
That's cool.
Okay.
Jin-Yi Yu: He uses
Jin-Yi Yu: The reason we care about the this one we call the Maxi ma
Jin-Yi Yu: Among
Jin-Yi Yu: All water vapor
Jin-Yi Yu: A parcel, or you can replace this pipe the atmosphere.
Jin-Yi Yu: Can hope.
Jin-Yi Yu: For is so this was confirm classes capital equation, he tell you that this among is proportional to exponential way. Sorry about the another key things that you know formula.
Jin-Yi Yu: The causes copper equation tell you that this water vapor month is dependent on temperature exponentially.
Jin-Yi Yu: See your air temperature of 10 degree, the maximum and one other, but you can hope so. This red line is based on his what he tell you he soil temperature access temperature determine the amount of water vapor. The maximum water. Yes. And this equation is combo into these nine
Jin-Yi Yu: What is so amazing about is nine.
Jin-Yi Yu: See today, as I say, there are two impact what we care about is maximum one is coming
Jin-Yi Yu: Implication DRS way, the implication has talk about climate implication, because what this class is all about. Now you say, if we take the quiz today if temperature today is 10 degree. Anybody know what is the average temperature averages surface temperature of ours right now.
Jin-Yi Yu: This is to be something you number, you need to memorize anybody on the committee Chrissy about
Jin-Yi Yu: 1515 degrees.
Jin-Yi Yu: Today about 300 or 288 K now to say that's today's climate. Climate because temperature is one thing 1015 degree. So, the maximum on water, they can hold is equal to about cities 10 is funding. So it's not tell me about. Okay, so we made sure how much water vapor
Jin-Yi Yu: Right, how much pressure, you can put us right so that's another path and you know this yet. OK. So the key thing is
Jin-Yi Yu: How present a planet our atmosphere can hold a maximum
Jin-Yi Yu: Amount of water vapor produced about problem in a bottle of water vapor. Now that's been given time in a contract one means can't release this among
Jin-Yi Yu: These Amanda carbon dioxide say
Jin-Yi Yu: X amount
Jin-Yi Yu: And because of water vapor can whole
Jin-Yi Yu: can absorb can trap radiation. Radiation try to escape to the coup de alchemy, and we have carbon dioxide even water vapor here which tool.
Jin-Yi Yu: Let's not worry about
Jin-Yi Yu: How we have H2O and
Jin-Yi Yu: Monica Perez story. So now we can drive car with us another carbon dioxide on our temperature to about
Jin-Yi Yu: Say 16 decreasing
Jin-Yi Yu: So we are going to allow our atmosphere to increase the maximum one of a button, you can hope increased from tell many paths to 20 me back. So what does that mean
Jin-Yi Yu: That means before you continue to scroll for me by running cap I reduce carbon dioxide and produce greenhouse effect. Oh, I must fear can only hope 12
Jin-Yi Yu: Molecule that tell me that I said tell molecule whatsoever. I can you produce carbon dioxide or am I coming to 60 degree. Oh, I must fear can know 20
Jin-Yi Yu: Molecule water vapor and what is itself a nada greenhouses greenhouse gases. Right. So, do you realize what, what have we done after we released covered asset we are not only in
Jin-Yi Yu: Heaven outside as a greenhouse gas into mass we we also allow our atmosphere to become more capable to hold more produce more greenhouse effect by dropping
Jin-Yi Yu: Hosting more water vapor everybody comes up. Yeah. Now, can we do on this cast copper equation. Now you say after keep them warm and welcoming a warmer climate, we go to UK, US temperature becomes 30 degrees C.
Jin-Yi Yu: Right, they said, Okay, we already saw doing this driving car for so many years. Let's forget about the worry about but driving the car say that's could still maintain the maximum amount
Jin-Yi Yu: Of carbon as I really still the same amount even know our climate is warm up to 30 degrees at night, you see that now you put you try, you really is the same x amount of carbon dioxide in this warmer climate, does the client you you
Jin-Yi Yu: Really as common as either cold or 10 degree common now. We had a woman come in. Now I see I increase the temperature, or is it because of this exponential relationship even in Hawaii temperature. Temperature is can agree if we only warm up one degree see
Jin-Yi Yu: Former one decrease it.
Jin-Yi Yu: By release cover NASA, we only increase this much of water vapor. A month into data management which is probably say find me back. But now, after we have a woman. A woman who he really is a semi mango cover NASA and also warm up a temperature by one degree. See, right there. Look at that.
Jin-Yi Yu: Because of exponential nature of this class Crapper equation, we are going to increase.
Jin-Yi Yu: Almost 20 minutes or more water vapor into our atmosphere compared when we do the same passing driving car. Reduce the same a lot of carbon dioxide.
Jin-Yi Yu: Our most will only increase find me about water vapor capacity for in a warmer climate to say missing assumption. How come it's going to warm up.
Jin-Yi Yu: Much, much more because now it can hold so much, other way, right, anybody can is point. And that's why, because our crosses copper equation process copper equation, what happened is
Jin-Yi Yu: We are going to make our global warming become uncontrollable become a runaway woman, and that's what it is so important concept.
Jin-Yi Yu: Class kappa for studying climate change, but stop global warming because of this exponential nature of this causes copper and question, tell us
Jin-Yi Yu: Our atmosphere can produce more and more and more and more and more greenhouse effect by holding exponential increase in my water vapor
Jin-Yi Yu: Based on this couple classes carpooling question everybody follow this argument.
Jin-Yi Yu: That's why this is a very important concept. Everybody has to recognize the other remember this term. Remember this exponential relationship between water vapor a map or capacity.
Jin-Yi Yu: Or the must be a can hold of water vapor is relationship temperature. Okay. Now, as I say, there's another important concept about the relevance of this implication of his cause classes crop room equation because it determining how soon.
Jin-Yi Yu: Anybody know how soon our air can reach saturation. Right.
Jin-Yi Yu: Because it tell you the amount water vapor air can hold depends on the temperature
Jin-Yi Yu: And why this one. This concept is important for weather. So when we say whether, may I ask you to give me a phenomena a veto variation you can sync about a phenomena that you can link to whether anybody
Jin-Yi Yu: You're looking sky. He said, has whether
Jin-Yi Yu: All the most fear doesn't is transparent. Right. Not so much in a certain outcome you cannot see them whenever we look at the sky, we see something that's because we have
Jin-Yi Yu: Cow right we have rainfall. What does a cow mean means water vapor content into liquid
Jin-Yi Yu: Water right
Jin-Yi Yu: Why vapor
Jin-Yi Yu: Change to liquid water because he reached come then sation. What does it mean English, Commissioner, you means this air is polluted or you fry up up up in the sky right initially on a cron
Yes.
Jin-Yi Yu: And in a gram is nothing inside it transparent but honey from 555 high and high into the sky. We see cow form right what happened inside this this balloon.
Jin-Yi Yu: Initially we have for a water vapor molecule. When you fry very high one kilometer talking. I'm in a 10 kilometer above ground. How many one that you have inside the room.
Jin-Yi Yu: For a more or less before police car still for right steer for what
Jin-Yi Yu: And how come I'm a gram. It is not an is unsaturated
Jin-Yi Yu: Because we didn't see any performance on a problem, but when Pluto high and her go. Go to the sky. We see crowd because you reach saturation
Jin-Yi Yu: Right, how can the same among the wallpaper here at point A and point B in the same amount of effort in reach saturation point either reach
Jin-Yi Yu: employ a it doesn't reach saturation and higher elevation be reached such you're here with the same amount of water in no reason in order for me to reach saturation is the amount of water vapor in the air has to equal to the maxima man saturation amount of water me but allowed
Jin-Yi Yu: By
Jin-Yi Yu: Process capital equation, right.
Jin-Yi Yu: Right classes classes copper equation.
Jin-Yi Yu: So even though
Jin-Yi Yu: We have a balloon.
Jin-Yi Yu: Please temperature is 15 degrees. See what happened when you fry high in the sky. He can't expand it. Right. So a temperature Apollo Trump to probably
Jin-Yi Yu: Minus five degrees C, or five degree. See for example. So the classes copper equation. They are you near the surface, even though you have sin for Mr sky me. Same for a moniker but because the temperature inside a truck.
Jin-Yi Yu: For the maximum amount of water vapor allow to stay in the air and such a low temperature has decreased because the CRAPPER Scrabble crisis crisis capital equation. So the air, the same umbrella for America become saturated, right, anybody can appoint
Jin-Yi Yu: So, this causes copper equation is important to determine why our with a form. High above in the sky, because the air when they go out expand the side his body and his temperature and across the car problem though.
Jin-Yi Yu: Is maximum amount of water vapor capacity and then make it produces condensation and why is it so important because we now call read the
Jin-Yi Yu: Release date in heat water vapor change the liquid water you release huge Amana cheat. So even though for human being. When we look at the sky, we see the sky. We are here my surface.
Jin-Yi Yu: You open your eyes look at the sky is skinny cow forming right
Jin-Yi Yu: So you saw
Jin-Yi Yu: Just a cow, cow in the sky, but in the physical sense when you see a cow form in the sky. What does natural tried to do in a physical sense, you try to release.
Jin-Yi Yu: Heat
Jin-Yi Yu: To the upper
Jin-Yi Yu: Atmosphere, where does it come from.
Jin-Yi Yu: The he was coming from near the surface. Initially, right, because a cold or warm and after knocking up go up, go up coco, coco, coco, coco, coco tropopause form cow release the heat. So whenever
Jin-Yi Yu: The heat release in Apple power hour troposphere initial comment on service, right. So when you see a cow physically summer dynamic on each other's culture to do each other. Nice. A temperature between selfies and the troposphere. So where does energy and service coming from anybody.
Jin-Yi Yu: The when I started doing one thing, try to move heat from surface hi to the sky and this key initially coming from were
Jin-Yi Yu: Coming from
Jin-Yi Yu: Right, because only surface can interrupt SAP sorry to hear when when the sorry this income into our current system. Listen, this is service.
Jin-Yi Yu: Summer comes in. This is our atmosphere, nobody, no air molecules can guess can do anything for solar radiation until Sunday. He the surface can absorb it by soil, soil by ocean and then always keep keep up.
Jin-Yi Yu: On that last surface temperature. So I'm SO I'M SO I'M SO also so Amina service so nature need to do something in nature, create these these
Jin-Yi Yu: Balloon a nice warm. I need a co op. And he kept expanding pika, pika, pika and NSF and NIH, the cancer comp room.
Jin-Yi Yu: Equation come to how much water vapor can stay calm much can stay comments can stay and then at one point the temperature truck to very quarter million across a couple pages that you reach saturation. Then release the heat or he that you receive from surface a full form crowd here.
Jin-Yi Yu: And release or a heat in Apple products must be so the
Jin-Yi Yu: Convert translated into a physical term whenever you see whether means our nature is try to move the heat. We have absorbed from Sinai from surveys
Jin-Yi Yu: High in total do attitude, our atmosphere. So to prevent surface temperature become super high end up at the master super cold. Everyone can appoint okay so
Jin-Yi Yu: Please, yes please.
Lucas: Just to see if I'm falling. So what is the the saturation value approximately when the cloud grapes, the saturation point
Jin-Yi Yu: Saturated means these the maximum amount of it. Maybe we can hope is equal to whatever whatever you have is that our aim.
Lucas: And now.
Jin-Yi Yu: That's determined by the temperature of the air. So what I mean. Let me give an example. So now we have one Air Corps. A we are one a copy
Jin-Yi Yu: And a as a temperature of 10 degrees. He has a temperature change a heretic car.
Jin-Yi Yu: Now it is not a cooker.
Jin-Yi Yu: Be has a temperature of 20 decreasing. So now inside a you have for a particular
Jin-Yi Yu: Insight, be it, you know, for the same amount water vapor. Okay, but because temp air temperature
Jin-Yi Yu: Problem. He has a very low temperature. So we use the cost of copper and gold equation to do a calculation we find out the maximum amount that they can hope is exactly equal to for a marker so this problem. A is going to form crowd back because reach saturation
Jin-Yi Yu: Saturation amount. One is a conceptual bowtie
Jin-Yi Yu: That I theorize maximum my water vapor. It can whole based on his temperature, but if you this is happens stay in
Jin-Yi Yu: Beta, there's no water they pay it off. So even though you have a very low temperature but it because you do not have all the way, but it still doesn't reach saturation. But, for example in this room, be
Jin-Yi Yu: Here has same amount on the market as a but because temperature is so warm is maxima idealized constructor Amanda one way, but it can hope is, for example, 40 water molecule but in reality.
Jin-Yi Yu: The situation only has four what America. So he's still far away from the conceptual capacity of water vapor, you can hope you can still pull another 36
Jin-Yi Yu: One more before you reach such a. So, this saturation element is ideal is a man. He has nothing to do with how much water, but you really have a particular room a particular location particular atmosphere, a very good point.
Jin-Yi Yu: So now.
Jin-Yi Yu: Let me go back here.
Jin-Yi Yu: So when we have a room co op can expand pika, pika, pika and decrease in temperature right and then cancer copper only question come in to tell us know alone can
Jin-Yi Yu: become such a some point right and then I mean, ask the last question before I returned back to our doctor who come to my crew getting pika, pika panico
Jin-Yi Yu: Can make me about is speaking instead of chat.
Because
Jin-Yi Yu: Because pressure in it must be a get smaller and smaller and smaller where you go high and high right
Jin-Yi Yu: So even in that case.
Jin-Yi Yu: What determine how much this balloon expand almost temperature going to try. It's going to be the first law of thermodynamics
Jin-Yi Yu: Okay. So whenever you look at a sky because I ability, your house, look at the sky in Irvine, you see cow right you know something's happening.
Jin-Yi Yu: Carson Scarborough equation is determine the air can form can reset your vision and I said hi there reach saturation in this high in the sky is because cuckoo down control by first law of thermodynamics, because first no sooner than me try to link.
Jin-Yi Yu: The change of your volume to a change of temperature. Uh huh. We are going to come to a point. So how much
Jin-Yi Yu: More can a volume change is going to be a link to how much is temperature can be quick, how much the temperature in the room can decrease is kind of depends on how much is the volume increase
Jin-Yi Yu: And there is a physical control these two changes and not physical. It's called first book semi dynamic. Okay, that's what I'm telling you the first lecture first law of thermodynamics and the second or Newton's laws of motion.
Jin-Yi Yu: Are two fundamental core physical control everything we study related to timing. Okay. And there's some other small fiscal but Basic Law attorneys took over someone has a question.
Jin-Yi Yu: Or is that a child is that also is that today, whenever I see it is already a few second after you reply. Okay, let me go back to our composition. The story of our kind of a we have in our community. So here
Jin-Yi Yu: The story is that Greece.
Jin-Yi Yu: Now we know outgassing volcano activity. So why do we have what cannot activity.
Jin-Yi Yu: What's the reason
Because of what
Jin-Yi Yu: Because we have allowed or internal heat
Jin-Yi Yu: was trapped inside how any planet when it is form right when he was from an outside of this planet cooling down cool now become a sorry pop right
Jin-Yi Yu: In a crack become support big pieces has called Peconic pray. Right. And inside we stay around lava liquid things but I very, very warm very warm very, very well. So this lava fronting
Jin-Yi Yu: This please Tony pray floating around this virus why our county can change to me as a call 15 minutes ago right Himalaya is because
Jin-Yi Yu: The India pensioner tectonic prayer Kibana drifting, drifting, drifting, drifting and then 15 meaning your score collide with Asia and then push pushing the Chrome app to produce Humana.
Jin-Yi Yu: Humana iOS developer is for you better go look at my screen here, we have fried served as an athlete and obey the service become participate Pato. What's the difference between these two situation for us surface condition a paper towel condition p the situation. He has allowed or what
Jin-Yi Yu: rock surface then is fresh. What right, so what does the rock service going to do. We're going to say that quickly when we have fresh rock.
Jin-Yi Yu: What is fresh rock to rock climbing.
Jin-Yi Yu: Is going to allow acid rain carbon dioxide dissolve in water for into the crown is going to produce chemical reaction.
Jin-Yi Yu: Which these fresh rock and or is covered outside in other must be is going to be deposited onto a crown Queen common as in most fear at the pilot into crown. What does that mean for climate.
Jin-Yi Yu: We have more coverage as a concentration or no comment as a contingency in the atmosphere.
Jin-Yi Yu: We're gonna know carbon dioxide concentrated and so when people are pro when India collect with Asia 50 million years ago.
Jin-Yi Yu: So is in the upper peninsula. Keep on
Jin-Yi Yu: With Asia and raise the paper to put by very fresh rock so 50 many years ago right now. This is present day. He has you know about 50 million years ago, our timing proper temperature or
Jin-Yi Yu: How or whatever. Just took over go down or cola 50 me many years ago.
Jin-Yi Yu: To call that
Jin-Yi Yu: Because of typical. So if you look at our peril common temperature record we realized 15 minutes ago, our temperature continue to track, beginning from 50
Jin-Yi Yu: Million years co quiet because we have fresh rock provided by the paper towel or now covered as I enter the most fear to be removed from a at must begin to surface and will reduce carbon dioxide amount you know atmosphere. And that's why
Jin-Yi Yu: Armenians here can scale we according to according to according to according down because of the paper or come back in the very end of the quarter. So now, the story is
Jin-Yi Yu: What happened to one data point of paper because classes copper equation tell us that as a must be a cannot hope I can only hope very small amount of water vapor. So most of what America has been contains to become ocean.
Jin-Yi Yu: And so on me early, the amount of water way, but this thing now atmosphere which is me challenging your memory of his number
Jin-Yi Yu: See he tell you the amount of honor, but you know Ottoman sphere is Powe 0.2% here and then let me ask you.
Jin-Yi Yu: This is how much match at the muscle mass is lot of April and the Amanda our atmosphere MS produced on the surface 100 money back. So you can say the total a mango air in our atmosphere.
Jin-Yi Yu: Is 100 money back. So whatever only come for 0.2% of them. So what is the typical water vapor. A man in Canada, meaning you know I must fear anybody
Jin-Yi Yu: To 1000 times 0.2% equal to
Jin-Yi Yu: 20 minutes, that's why you see us go
Jin-Yi Yu: To any style code or castles copper equation.
Jin-Yi Yu: I will say in Crimea and literature. You can see that the amount of water vapor our atmosphere has his clothes equal to about 20 minutes okay let me go here, go here, go to adoration, the humidity among
Jin-Yi Yu: among a lot of people are the most fear.
Jin-Yi Yu: Has rather than showing this one.
Jin-Yi Yu: Is somewhere around 2020. So, our time is 15 degree. Right. So you can see that the physical tell you the maximum amount. What am I making hope is somewhere close to candy UNITA mean anyone can apply
Jin-Yi Yu: So you don't even need to remember is this this concept, this number you should remember. Okay, let me quickly go back to finishing my
Jin-Yi Yu: Also, the most fear story. So what are they will come and say become water become ocean. So only small amount that I happen to come in after this I say when you have
Jin-Yi Yu: Been volcano eruption happened. He put us on our covered as I, you know, the must be atmosphere. However, all his carbon dioxide.
Jin-Yi Yu: Because we've caught up on water vapor condensate become Cropsey crown means condensation and you've produced rainfall
Jin-Yi Yu: Ray's gonna force through atmosphere and all is carbon dioxide. The volcano eruption inject into other must be a will dissolve into well
Jin-Yi Yu: Is up in the rain water M commerce, as I go into Romana become what MC Ren right become excellent week company. Excellent. And this company x ray four kilogram will call
Jin-Yi Yu: In chemical reaction least these bedrock and then we'll knock all these covered as I become syndicate rock.
Jin-Yi Yu: Here. So all the covenants, I can remove and become that's what depends on how much the rain service roster is you have, the more rock service you had during any patio comma kind of our Earth, they're more chemical reaction. This process is called chemical weathering.
Jin-Yi Yu: Ran for in the acquisition. See this chemical weathering process is going to keep on remove carbon apps that out of our atmosphere. Oh, boom us you have rainfall
Jin-Yi Yu: Right. And then so, and only small a mango water vapor is now our small manga come up as that but what happened to match it, because this chemical is not active
Jin-Yi Yu: Is not suitable in water. It doesn't go into the water and it's very heavy monitoring because it's so heavy emotionally emotionally in other must be so it doesn't have another connect and kinetic energy to escape.
Jin-Yi Yu: From the control property. So gravity strongly hope our narrative because they're very Amy.
Jin-Yi Yu: Marker. That's why nitrogen still standing. So everybody can appoint studies whole story of outgassing is that we have. Okay, no activity. Okay, now produce water vapor per cannot produce carbon dioxide. Okay, now proteins Nigel nitrogen but whatever way we cannot stay alert.
Jin-Yi Yu: Stay in at MS K become ruin and read is going to capture cup and I'll say it, bring it again to surveys. So at the end.
Jin-Yi Yu: There's not much of an automatic not much to cover NASA, the maximum amount you have is nitrogen, right. So, now tell the story why we have so much nitrogen in our MSP so why the story is important if you want to explain why Mars is so cold.
Jin-Yi Yu: Why it is so cold. The story has to begin from volcano.
Jin-Yi Yu: Right white master is so cool because it does not have a lot of carbon dioxide right but didn't any planet upon your form, you should issue any punish you trap and our heat
Jin-Yi Yu: Inside the premiere and that he has to go out of a volcano. Nice. You also happen on mass right yes it did happen in a mask is produced outgassing produce or AWS, Kansas, but
Jin-Yi Yu: What happened to match that all this volcano activity tied down very quickly.
Jin-Yi Yu: Because Mars is very compared us is very one
Jin-Yi Yu: Very small. So it's a small planet so it doesn't have a lot of internal heat. So it's volcanic activity Titan very quickly.
Jin-Yi Yu: So there's no longer be able to inject carbon dioxide. That's why mass is so cool. So that's what the story is important because every step PO in a concept to determine what is going to happen to your
Jin-Yi Yu: Temperature. OK, now let's quickly go through why the second apartment guess is as little as because 5.5 billion years ago, we began to have live and invite is going to put up put this photosynthesis. Photosynthesis coteries carbon dioxide. So why a lot of
Jin-Yi Yu: Why water vapor
Jin-Yi Yu: And carbon dioxide concentrations drop the oxygen, they will go up, it becomes second abandon and then why we have aka aka just radiative came from.
Jin-Yi Yu: Premise bedrock so that become a, Sir. Sir, abundant. Good. Okay, so that's the way I can see that the first story. Everybody should try to be able to express
Jin-Yi Yu: To the composition of atmosphere. So now we have all these important guest is a small man guess
Jin-Yi Yu: So now after we know what kind of atmosphere we have when we say what kinds the composition of the characteristic. OK, now let's try to describe
Jin-Yi Yu: The property of how awesome our sphere, and we want to describe a property or what are the must be that matter to our life and our life depends on postings.
Jin-Yi Yu: Right, we need to have energy to grow or fool in our environment. So for us, we also need sunlight to keep us warm. Right. And what was the water. So we need energy
Jin-Yi Yu: And water.
Jin-Yi Yu: And which probably are the must be read the water humility that's keeping Hey Ray that's focused on energy right because our I need energy and we also affect the energy. What is the most obvious form of energy that human being can feel anybody
Jin-Yi Yu: One is temperature. The warmer the air temperature and warmer. You feel the more energy you can see, not a holding, what is the other most obvious for more energy human experience when
Jin-Yi Yu: Right. Those are two most obvious for more energy. So what's the difference between these two form energy temperature represent what poker energy
Jin-Yi Yu: Energy
Jin-Yi Yu: Can be in any story.
Jin-Yi Yu: A few formula for
Jin-Yi Yu: One is internal energy
Jin-Yi Yu: When is what kinetic
Jin-Yi Yu: Energy and then she's reading to motion.
Jin-Yi Yu: In energy is not here to motion or maybe the potential of our monitor right so air temperature we present
Jin-Yi Yu: Our internal energy
Jin-Yi Yu: Oh,
Jin-Yi Yu: Yeah.
Jin-Yi Yu: Right. And then when is also relatable kinetic
Jin-Yi Yu: For more energy.
Jin-Yi Yu: Of also air more of your
Jin-Yi Yu: host of different economic pie. Is this a molecule oxygen has the moon. Right. And then this internal copied me H2O, for example, H two O
Jin-Yi Yu: It producing vibration or is H2O. Keep on rotation or oh no criticism move very, very fast. I said, okay, as call kinetic energy. So whenever individually individual a marker is vibrating moving around.
Jin-Yi Yu: And a molecule enable us to reflect us temperature. Now watch this air Monica move around.
Jin-Yi Yu: In the molecular level is higher the temperature, and when is macroscopic pick view of this whole app. Also, another inside the moon, not an individual molecular
Jin-Yi Yu: level but on the whole piece again. So we need to describe all these energy form right and then we use water vapor to discard water. What does a pressure to
Jin-Yi Yu: White. If you look at any mathematical equation that we use to appeal computer model for to weather forecasting. If you want to use computer model to simulate a motion water motion you have come up. We use five to six.
Jin-Yi Yu: Equation this five to six equation is coming from two or three Formula One is first of all have summer dynamic. Second is second.
Jin-Yi Yu: Newton's law of motion, Sergio as continuity equation. So if you to the economy modeling in our department you read on a paper it is quieter n caste system kind of model.
Jin-Yi Yu: The model user guy will give you six equation for the 60 question they all coming from history physical law and inside his sixth equation, you will see variable temperature, pressure, humidity, so knowing
Jin-Yi Yu: East West with no sauce. When and vertical go check any of these scientific paper. You are exactly see this six available. So I put this six variable here.
Jin-Yi Yu: Tonight, just because I suck them because those are the complete set of fundamental variable property of atmosphere, we have two major we have to understand in order to study timing and meteorology.
Jin-Yi Yu: And I'll give you a reason because temperature represent internal energy when we present kinetic energy. Right. And why temperature is important because our climate is a solar power machine or a solar energy coming first change our temperature
Jin-Yi Yu: But our must be aware, then comment, it's going to move around by when. Right. And then how can we link that temperature immediately power by solar energy to something that its kinetic energy that we care about.
Jin-Yi Yu: So in between temperature. And when we need one hour bearable to link them. What is that outsourcing pressure
Jin-Yi Yu: Pressure is Amanda mass, mass via when you have mass you put weight when you produce way it become a force.
Jin-Yi Yu: And become any coin is a mass, how much mass you have
Jin-Yi Yu: My pimp, it must be depends on how warm or cold air is now warmer air temperature. No, by no means because when you have smaller
Jin-Yi Yu: Match match with a smaller amount. Ms. You're going to put a smaller amount of force someone. Oh man, I'm gonna try RICO win.
Jin-Yi Yu: over Alaska. You have a very cold temperature. So as a mother. It is the you know the most part this location is very high density. He produced are not on mass, mass produce high pressure high prices can try.
Jin-Yi Yu: Stronger when a manager upon. So the reason we have this variable. Let's not forget about moisture first because everything with the sky in this class.
Jin-Yi Yu: Can be a prime, can we apply or anything with them. And those are the must be to mass and mass for the most fear, can we, how can we not, we can
Jin-Yi Yu: Because Mars are the must be also control by the same equation first know so my dynamic second or noodles raw emotion and conviviality normally see a difference between
Jin-Yi Yu: Us at MSP and Mars or the Moon speeds that humanity, a man so whatever we discussed for our class. We do not need to have humility, but because of the most
Jin-Yi Yu: Is our most for the most fear. So we need to add one more bearable. Otherwise, we only need to have temperature to describe how much internal energy we receive from somewhere. And we use to describe how much connect energy
Jin-Yi Yu: After machine move produce motion. Right. And we need pressure as the conveyor belt of our machine to
Jin-Yi Yu: Connect the gasoline. We add into the solar power into the machine to move the car. Our communication and that mechanical path to really try these things around.
Jin-Yi Yu: Is pressure a vertical upon what so that's why they are important. So now the reason it squared is eternity. Are you a fee baleful pre present a physical meaning.
Jin-Yi Yu: They are not just one decreasing decreasing and not just pulled me her weight is one was a Navy bringing something
Jin-Yi Yu: Because the first three choco taco truck give you energy view of our climate, you can see our climate.
Jin-Yi Yu: From an energy point of view we not go into the detail about where you have happy sale Walker sell anything you don't need to care about you just kept from energy point of view, what kind of motion, we should observe in are coming here. So now I'm going to go through every variable.
Jin-Yi Yu: So when we go through all these variable, we are gonna first
Jin-Yi Yu: Refresh Yourself. What is the fiscal meaning. Second, what is the unit for a simple and then what is the
Jin-Yi Yu: President name distribution of these balco in our US system. Okay, so that's a stream process. We're going to repeat us raising definition uni, the real war distribution. OK, so
Jin-Yi Yu: Now let's move on. First, I can better let me quickly go back here. What does this existence of moisture change our climate machine.
Jin-Yi Yu: Aftermath is very dry. There's no humidity.
Jin-Yi Yu: Humidity right water vapor. So the condemnation and mass and us kind of should question defense.
Jin-Yi Yu: Due to this exists the water waiver anybody
Jin-Yi Yu: If you have a Tri County machine, the machine is very an efficient.
Jin-Yi Yu: You're not going to produce an efficient way of using your solar power us candy machine has moisture
Jin-Yi Yu: So you have to recognize the reason moisture so important is how you fishing out candy machine is going to run to walk, how soon this warm
Jin-Yi Yu: Air and equator coil in the polar region comics by our emotion depends on how much whatever we have
Jin-Yi Yu: If we do not have water every other month is completely dry. What is going to see, we're gonna have a winter storm to bring one
Jin-Yi Yu: For equator two polar region. So every window, you're going to see windows. The windows. The windows. The windows.
Jin-Yi Yu: Because our other must be so try is soy and efficient, we need to produce a Windows Phone TO to miss parents this equipment port temperature difference
Jin-Yi Yu: And also, if you go outside your beauty me anytime after know you see the Sunday afternoon, if our MSP is very trying new me after me can see
Jin-Yi Yu: Because of all of the must be so and efficient to move here around with very dry air, making it up to put this last summer strong enough in order to bring the heat send SMS survey.
Jin-Yi Yu: Must be because we come out the most to get more Moisture. Moisture. Moisture. Now, we don't need to have so many summer strong activity. We do not need to have so many winter snow.
Jin-Yi Yu: Too bad and energy around the Earth. Anybody can apply. So that's why motion so beautiful, so important, it changed the efficiency of alchemy, and whether my ship. Okay. Since I run through to the end of the lecture I'm going to stop here. Continue.
Jin-Yi Yu: describing this property. So, as I say, I believe. Some of you already know the concept, the things I mentioned in this textbook or in this lecture.
Jin-Yi Yu: But I wish you get a physical meaning our last equation knows when Apple from a crime. Sighs overview. OK, so I'll stop here and we will continue on.
Jin-Yi Yu: Thursday. And these are basically we have a from one account we have is our office. All right, so your question. You can come to the room meeting can ask me question and then I'll see you in the office, all I'm a talker department event. Okay. Thank you. Anybody
Lucas: Any homework this this week.
Jin-Yi Yu: Almost kind of issue on Thursday.
Lucas: Thursday. Okay.
Jin-Yi Yu: Okay, I'll send you the homework by email, and then you can you next Thursday.
Jin-Yi Yu: Great. Okay. Great.
Jin-Yi Yu: Thank you my
Jerry Lin: Question is a permanent at two or one because on my calendar, I have
Jin-Yi Yu: One is, is in my office hour
Jin-Yi Yu: Every Tuesday at
Jin-Yi Yu: One or 130 right
Armando Vilchez: So one today.
Jin-Yi Yu: Obviously became the
Jin-Yi Yu: Criteria. How did you say
Jerry Lin: Maybe broke down wrong, but my calendar says
Jin-Yi Yu: Yes, to a 91120 so there's another caution I need to reschedule my office. Oh, I didn't know. Yeah. And I was like, okay, so I see you at two o'clock. That's a department event.
Juan Tolento: The event is that
Juan Tolento: Is that one o'clock is what we're saying.
Jin-Yi Yu: No, no, no, the Department
Jin-Yi Yu: Come back. He then he said, what time poor crazy
Armando Vilchez: Melanie, I want
Ved Bhoot: Yeah Melis she sent a email at around 1030 it says
Ved Bhoot: 1pm 1pm yeah
Jin-Yi Yu: Oh, okay. Well, I always see that. See you at a department event and please excuse me. Yeah, actually. It's one o'clock. I'm sorry. Look at my current is one
Jin-Yi Yu: Please excuse me by skill pronounce your name, not 100% accuracy. OK, I see you in one. Thank you, everybody.
Nicholas Pham: On either stop.
Nicholas Pham: Stop ship.
Jin-Yi Yu: Okay bye everybody.
