an episode of strong trade winds and unusually low sea-surface temperatures in the central and

eastern Pacific

La Nina

2

the seasonal reversal of wind direction associated with large

continents

monsoon

3

the nightly downslope winds commonly found in mountain

valleys

mountain breeze

4

that mass movement of ocean water that is either wind driven or

imitated by temperatures and saline content of the seawater

ocean current

5

the stormy frontal zone separating air masses of polar origin from air

masses of tropical origin

polar front

6

are strong, extremely dry offshore winds that characteristically sweep

through in Southern California and northern Baja California in late fall

and winter

Santa Ana

7

is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually

nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted

surface water

upwelling

8

small convective cells that exist for a short time such as thunderstorms

or tornadoes

mesoscale winds

9

a wind observed in the interior West of North America

chinook

10

are a pattern of wind that are found in bands around the Earth's

equatorial region

Trade winds

11

The United States does not experience a monsoon.

false

12

Seasonal changes in pressure are greater over continents than over

the oceans.

true

13

Jet stream winds are completely distinct from the mid-latitude

westerlies.

false

14

For much of South and Southeast Asia, winter is a period characterized

by relatively dry conditions.

true

15

The wind called the "norther" in Texas is really not a local wind but rather is a

synoptic scale (macroscale) phenomenon.

true

16

The areas of abundant rainfall on the earth tend to be

near the equator and in mid-latitudes.

17

Concerning rainfall patterns, areas of persistent high pressure tend to

cause.

desert regions.

18

Why do westerly winds prevail at upper altitudes?

rotation of the earth and equator to pole temperature contrast

19

Surface high pressure zones are usually associated with

clear or nearly clear weather.

20

Jet streams are associated with fronts because of the

large temperature gradient.

21

Microscale winds generally last for:

a few seconds.

22

Most of the United States is situated in which zone of prevailing winds?

westerlies

23

The prevailing winds that blow from the horse latitudes toward the

doldrums are called:

trade winds.

24

When are upper air winds fastest?

In the winter

25

Summertime wildfires in California are fanned by:

the Santa Ana winds.

26

Jet streams occur where?

occur at 25,000 to 40,000 feet in middle latitudes.

27

Winds are usually named for.

the direction or place from which they are blowing.

28

The prevailing winds that tend to influence cities such as Chicago

and New York City are

westerlies.

29

The definition of the word 'monsoon' means

seasonal wind shift.

30

The amount of precipitation received at a given location is

primarily controlled by

circulation patterns in the atmosphere.
