Weather And Climate

Front 1

State of the atmosphere at a specific time and place; determined by factors including air pressure, amount of moisture in the air, temperature, and wind

Back 1

Weather

Front 2

Amount of water vapor held in the air.

Back 2

Humidity

Front 3

Measure of the amount of moisture held in the air compared with the amount it can hold at a given temperature; can range from zero percent to 100 percent

Back 3

Relative Humidity

Front 4

Temperature at which air is saturated and condensation forms.

Back 4

Dew Point

Front 5

A stratus cloud that forms when air is cooled to its dew point near the ground.

Back 5

Fog

Front 6

Water falling from clouds-including rain, snow, sleet, and hail-whose form is determined by air temperature.

Back 6

Precipitation

Front 7

Large body of air that has the same characteristics of temperature and moisture content as the part of Earth's surface over which it formed.

Back 7

Air Mass

Front 8

Boundary between two air masses with different temperatures, density, or moisture; can be cold, warm, occluded, and stationary

Front 9

Violent, whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead.

Back 9

Tornado

Front 10

Large, severe storm that forms over tropical oceans, has winds of at least 120 km/h, and loses power when it reaches land.

Back 10

Hurricane

Front 11

Winter storm that lasts at least 3 h with temperatures of 212°C or below, poor visibility, and winds of at least 51 km/h

Blizzard

Front 12

Studies weather and uses information from Doppler radar, weather satellites, computers and other instruments to make weather maps and provide forecasts.

Meteorologist

Front 13

Average weather pattern in an area over a long period of time; can be classified by temperature, humidity, precipitation, and vegetation.

Climate

Front 14

Climate zone that receives the most solar radiation, is located between latitudes 23°N and 23°S, and is always hot, except at high elevations.

Back 14

Tropics

Front 15

Climate zones that receive solar radiation at a low angle, extend from 66°N and 66°S latitude to the poles, and are never warm.

Back 15

Polar Zone

Front 16

Climate zones with moderate temperatures that are located between the tropics and the polar zones.

Back 16

Temperate Zones

Front 17

Short period of climatic change in an area caused by the tilt of Earth's axis as Earth revolves around the Sun
