A cold front

• typically has heavy, short-lived precipitation

• moves slower than the warm front

• is associated with stratus clouds

• pushes cold air up above the warm air

Which air masses are responsible for most of the rainfall over the eastern 2/3rds of the United States?

• mT air masses from the northern interior of Mexico and the southwestern U.S.

• mT air masses from the Gulf of Mexico, Caribbean, Atlantic region

• mP air masses from the northern Pacific

• cP air masses from Canada

This is the air mass that is usually responsible for lake-effect snow

• cP

• mT

• cT

• mP

In mid-latitude cyclones, after the cold front has passed, one would experience

• a shift to warmer, wetter conditions than before

• no change in temperature or humidity conditions

• a shift to cooler, drier conditions than before

• a shift to warmer, drier conditions than before

A cumulus humilis cloud

• is always composed of ice crystals

• is also called the lenticular cloud

• is formed by high pressure

• is formed by convection

Raindrops that freeze on contact with solid objects are called

• rain

• sleet

• glaze/freezing rain

• snow

Which of the following locations would be most likely to experience precipitation that was created through the collision-coalescence process

• Helsinki, Finland (60ºN)

• Barrow, Alaska (71ºN)

• Quito, Ecuador (0º)

Most mid-latitude cyclones develop along

• the subtropical high pressure zone

• the subtropcial from

• the polar front

• the ITCZ

The area between the cold and the warm front in a mature mid-latitude cyclone is called

• the Rossby sector

• the warm sector

• the cold sector

• the cT sector
