Features of the model
Ocean influence on weather
Cold air tries to dive below or push under warm air
Higher pressure N of cold front so bending
is towards lower pressure
Cold air pushes warm air/front
Low pressure intrusion into cold front
Warm air rises (with or without water) at both
fronts & yields precipitation at the fronts
Cold front pushes warm front
Eventually part of front is cut off and moves
Internal structure of a mature hurricane.
Where hurricanes form (areas of high humidity and warm air over warm water)
