First Law of Thermodynamics = 10˚C/km cooling rate as air ascends, warming rate as it descends.
Assume the hurricane is 20 km tall
If the air descends in the eye from the top of the hurricane all the way to the sea surface, it will
cover 20 km. It will also compressionally warm the entire trip.
20 km * 10˚C/km = ???
(Air cannot descend from the tropopause all the way to the surface!)
Hurricane Eyes Are Warm…
