Unit 1 weather dynamics

Question 1

A cool, dry air mass which forms over the land in the far North.

Answer 1

Continental Polar air mass

Question 2

A movement of air from a high pressure system to a low pressure system

Answer 2

Wind

Question 3

The concept that an object moving straight across a rotating surface will have its path twist to the right or left.

Answer 3

Coriolis Effect

Question 4

A warm, moist air mass which forms over the Caribbean

Answer 4

Maritime Tropical Air mass

Question 5

A large wind pattern in both the Northern and Southern Hemispheres, between the latitudes of 30o and 60o.

Answer 5

Mid latitude westerlies (Prevailing Westerlies)

Question 6

High speed winds at high altitudes (~7000m) at the latitudes 30o and 60o; have the ability to steer weather patterns.

Answer 6

Jet Stream

Question 7

The ocean current which forms near the Carribean and follows the east coast of North America up to Newfoundland. (Slow and Warm)

Answer 7

Gulf Stream

Question 8

Large bodies of air in which the temperature and moisture content at a specific height are the same.

Answer 8

Air Mass

Question 9

Advancing warm air displaces cold air along a warm front, which develops a gradual boundary slope.

Answer 9

Warm Front

Question 10

When cold, dense air displaces warm air, it forces the warm air which is less dense, up along a steep slope.

Answer 10

Cold front

Question 11

develops as a result of
the meeting of two air
masses with different
characteristics

Answer 11

Front

Question 12

When two air masses meet but neither advances, the boundary between them stalls.

Answer 12

Stationary front

Question 13

Sometimes a cold air mass moves so fast that it overtakes a warm front forcing the warm air up

Answer 13

Occluded Front
