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