Question

1.) why are longer periods of precipitation associated with a warm front compared to a cold front?

2.) Following the passage of a cold front, cold air ___ and undergoes adiabatic _____ leading to clear skys and fairer weather

a. rises/expansion

b. rises/ compression

c. sinks/expansion

d. sinks/ compression

3.) What happens to the warm mT air along an occluded front

a. the mT air pushes the cold air way and reopens a gap between the two cold air masses

b. the mT air is overriden and covered by overlying cold air

c. the mT air is lifted off the ground by the converging cold air masses and is no longer in contact with the ground

4.) why is there a good chance for precipitation along an occluded front?

a. warm, moist air is lifted and cooled when overtaken by the cold front

b. warm, moist air pushes away the advancing cold front and is afterwards heated by the sun

c. warm, moist air is heated to even higher temperatures when covered by cold air

5.) During the ____, the belt of subpolar lows and the polar front are farthest south in north america, and the central united states will experience a ____ frequency of passing middle latitude cyclones

a. summer/ lesser

b. winter/ greater

c. winter/lesser

Explanation / Answer

A cold front; where colder air overtakes warmer air, the front is very steep, and is associated with cyclonic rain, which is heavier but occurs over a shorter period.

With a warm front, where the warmer air rises more gradually over the colder air, and the front is wedge shaped, rather than steep. The warm air cools at it rises, forming warm front precipitation which is lighter, steadier, and lasts for a longer period that is main reasons.
