Pressure Structure
qThe
horizontal pressure gradient with altitude decreases slowly.
qAt about 400
mb, pressures within
the storm are approximate to that outside.
qSurface-400mb:
Cyclonic circulation.
q400mb-tropopause:
anticyclonic circulation.
q The upper portions of the storm are blanketed by a cirrus
cloud cap due to overall low temperatures.
