1

is the force exerted onto a surface by the weight of the air

Air Pressure

2

the envelope of gases surrounding the earth or another planet.

Atmosphere

3

an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.

Barometer

4

another term for atmospheric pressure.
the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).

Barometric Pressure

5

of or denoting a scale of temperature in which water freezes at 0° and boils at 100° under standard conditions.

Celusius

6

the weather conditions prevailing in an area in general or over a long period.

Climate

7

is a dense towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents.

Cumulonimbus Cloud

8

are often described as "puffy", "cotton-like" or "fluffy" in appearance, and have flat bases. being low-level clouds, are generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form.

Cumulus Cloud

9

the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.

Dew Cloud

10

a prolonged period of abnormally low rainfall; a shortage of water resulting from this.

Drought

11

the temperature at which a liquid turns into a solid when cooled.

Freezing Point

12

A storm with a violent wind, in particular a tropical cyclone in the Caribbean.
a wind of force 12 on the Beaufort scale (equal to or exceeding 64 knots or 74 mph).

Hurricane

13

a rotating funnel-shaped cloud forming the core of a tornado or waterspout.

Funnel Cloud

14

a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.

Global Warming

15

pellets of frozen rain that fall in showers from cumulonimbus clouds.

Hail

16

the state or quality of being humid.
a quantity representing the amount of water vapor in the atmosphere or a gas.

Humidity

17

the branch of science concerned with the processes and phenomena of the atmosphere, especially as a means of forecasting the weather.

Meteorology

18

the action or process of precipitating a substance from a solution.
rain, snow, sleet, or hail that falls to the ground.

Precipitation

19

a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.

Thunder

20

a storm with thunder and lightning and typically also heavy rain or hail.

Thunderstorm

21

a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.

Tornado

22

forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph.

Tropical Depression

23

a tropical storm in the region of the Indian or western Pacific oceans.

Typhoon

24

the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.

Weather

25

is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity. This clashing of air types causes weather: rain, snow, cold days, hot days, and windy days

Front

26

a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground

Cloud
