Front 1

anemometer

Back 1

An instrument used to measure wind SPEED.

Front 2

wind chill factor

Back 2

The increased cooling that a wind can cause.

Front 3

local winds

Back 3

winds that blow over short distances

Front 4

land breeze

Back 4

The flow of air from land to a body of water.

Front 5

monsoons

Back 5

Sea and land breezes over a large region that change direction with the seasons.

Front 6

sea breeze

Back 6

A wind that blows from an ocean or lake onto the land.

Front 7

global winds

Back 7

Winds that blow steadily from specific directions over long distances.

Front 8

Coriolis effect

Back 8

The way the Earth's rotation makes winds curve.

Front 9

Monsoons happen in _______.

Back 9

Monsoons happen in SOUTH AND SOUTHEAST ASIA

Front 10

The movement of air between the equator and the poles produces?

Back 10

Global winds

Front 11

wind vane

Back 11

A device which determines wind DIRECTION.

Front 12

The name of a wind tells you__________.

Back 12

The name of a wind tells you the direction a wind IS COMING FROM.

Front 13

Name the three major global wind belts.

Back 13

1. trade winds
2. prevailing westerlies
3. polar easterlies

Front 14

doldrums

Back 14

A calm area near the Equator where warm air rises. There is little or no wind.
(The trade winds meet at the doldrums)

Front 15

horse latitudes

Back 15

Belt of calm air at about 30 degrees north and south. Becalmed sailors ran out of food and threw their horses overboard here.

Front 16

Trade winds

Back 16

Belt of winds between 30 degrees N or S and the Equator. The winds blow towards the Equator and are turned west by the Coriolis effect.

Front 17

prevailing westerlies

Back 17

Belt of winds between 30 and 60 degrees N or S. The winds blow from the SW in the northern hemisphere and from the SW in the southern hemisphere.

Front 18

Polar easterlies

Back 18

Belt of winds from the poles to 60 degrees N or S. Winds blow from the poles and and are turned by the Coriolis effect to the west.

Front 19

polar front

Back 19

At 60 degrees N and S the polar easterlies meet the prevailing westerlies mixing warm and cold air. The polar front has a MAJOR effect on weather in the USA.

Front 20

jet streams

Back 20

Global west winds found 10 kilometers above the Earth and only a few kilometers deep. They blow at 200 to 400 kilometers an hour.

Front 21

How do jet streams effect airplanes?

Back 21

Airplanes flying east can be helped by flying in the jet stream, gaining speed and saving fuel. Airplanes flying west are slowed down.

Front 22

What is the cause of local winds?

Back 22

The unequal heating of Earth's surface within a small area.

Front 23

All winds are caused by?

Back 23

differences in air pressure
