Flashcards in Weather Deck (27):
1

The definition of air pressure 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.

barometric pressure

5

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

Celsius

6

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

climate

7


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

cloud

8

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

cumulonimbus cloud

9

are puffy clouds that sometimes look like pieces of floating cotton.

cumulus cloud

10


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

weather

11

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

dew point

12

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

drought

13


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

freezing point

14


a storm with a violent wind, in particular a tropical cyclone in the Caribbean.

hurricane

15

a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics.

front

16


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

funnel cloud

17

a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect

global warming

18

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

hail

19

atmospheric moisture.

humidity

20

The study of weather

meteorology

21

Rain hail sleet or snow

precipitation

22

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

thunder

23

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

thunderstorm

24

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

tornado

25

an atmospheric low-pressure system originating in the tropics

tropical depression

26

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

typhoon

27

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