ok Fr tho, we gotta lockin! CHAPTER 8

A cool and moist airmass associated with a coast.

mP – Maritime polar

A warm and dry airmass located over land. 

cT – Continental tropical

A very cold and very dry airmass located over land. 

cA – Continental arctic

A warm and moist airmass associated with a coast. 

mT – Maritime tropical

A warm airmass existing only in the Northern Hemisphere. 

cP – Continental polar

Which is the coldest air mass?

Ca- continue Arctic

During the summer months, which is the warmest air mass?

cT - contenue tropical

When warm air collides with a cold air front, its slow journey up the slope of the cold air front causes longer rains. True or false

true -When warm air collides with a cold air front, its slow journey up the slope of the cold air front causes longer rains.

When a cold air front moves rapidly toward a warm air front, there isn’t time to predict the light and longer-lasting rains that result from the warm air dissipating. TRUE OR FALSE

FALSE - When a cold air front moves rapidly toward a warm air front, there isn’t time to predict the light and longer-lasting rains that result from the warm air dissipating.

Violent weather are more commonly associated with a cold front. TRUE OR FLASE

TRUE - Violent weather are more commonly associated with a cold front.

Rainstorms are generally shorter when a cold air front comes in quickly and collides with a warm air front. TRUE OR FALSE

TRUE -Rainstorms are generally shorter when a cold air front comes in quickly and collides with a warm air front.

Long-lasting rainstorms occur when a cold air front encounters a receding warm air front.TRUE OR FALSE

FLASE - Long-lasting rainstorms occur when a cold air front encounters a receding warm air front.

Why does rain occur near a cold front?

Rising warm air cools, resulting in cloud formation and rain

How are rain patterns different near warm and cold fronts?

Rain near a cold front occurs over a smaller spatial area and is more intense than near a warm front

Where does rain occur in a warm front?

Rain occurs along and in front of a warm front

What are midlatitude cyclones

Migrating low-pressure cells that move in the band of the westerlies

What happens when air masses of different temperatures meet?

Well-defined boundaries form between the air masses

Which of the following statements about midlatitudes cyclones are correct?

a

The cold front advances faster than the center of the storm, and the warm front advances more slowly than the center

b

Surface winds move counterclockwise.

c

The entire cyclone moves from west to east.

d

All of the above

What is occlusion in a midlatitude cyclone?

Occlusion is the process by which a cold front overtakes a warm front

When do midlatitude cyclones stop producing storms?

When the cold front has completely taken over the warm front

Midlatitude cyclones in the United States rotate in which direction?

Counterclockwise

Mid-latitude or  "__________" cyclones are large traveling atmospheric cyclonic storms up to 2000 km (1250 mi) in diameter with centers of low atmospheric pressure.

a

extra-tropical

b

frontal

c

wave

d

All of the above

A cold air mass originating over an ocean is designated

mP

Most warm air masses affecting North America

are moist.

Summer afternoon thundershowers in the southeastern United States are more than likely a result of

convection lifting.

Orographic lifting is

air forced to rise over a barrier, such as a mountain range.

A rainshadow is most often associated with which atmospheric lifting mechanism?

Orographic

Wave cyclones are most common

in the mid-latitudes.

In the United States, mid-latitude cyclone development is usually the result of

the interaction of cP and mT air masses.
