Term
Three common means of lifting air are orographic lifting, wind convergence, and:
Definition
lifting by fronts
Term
Air that rises by itself would be called

how quickly heat is lost.
Term
Mid-latitude cyclones in the northern hemisphere
Definition
circulate counterclockwise

Hurricanes DO NOT form
Definition
at the equator
Term
The destruction at Galveston by the hurricane of 1900 was primarily due to

Term
In 2008, Hurricane Ike, although only a Category 2 at landfall, caused extensive destruction on the coast east of Galveston by
Definition
storm surge
Term
In both Hurricane Camille and Hurricane Katrina the Mississippi coast was devastated because
Definition
it was on the right side of the eye.
Term
The potential risk of flooding in New Orleans
Definition
was high because much of the city was below sea level.
Term
The destruction of Hurricane Katrina was made worse by
