Flashcards in Weather And Climate Deck (34):
1

Air pressure

The air that composes the atmosphere is made of many different gases. ... When gravity acts on the air, the air exerts a force upon the earth called pressure. The typical pressure at sea level is 1013.25 millibars or 14.7 pounds per square inch. A millibar is a unit that is used to report the the atmospheric pressure.

2

Tropical

pertaining to, characteristic of, occurring in, or inhabiting the tropics, especially the humid tropics:

3

Celsius


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

4

Cumulus cloud

Cumulus clouds are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile.

5

Cirrus cloud

Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair

6

Thermometer

Definition of thermometer. : an instrument for determining temperature; especially : one consisting of a glass bulb attached to a fine tube of glass with a numbered scale and containing a liquid (such as mercury or colored alcohol) that is sealed in and rises and falls with changes of temperature.

7

Tropical depression

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Wikipedia

8

Ocean current

An ocean current is a seasonal directed movement of sea water generated by forces acting upon this mean flow, such as wind, the Coriolis effect, breaking waves, cabbeling, temperature and salinity

9

Dew point

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

10

Hurricane

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).

11

Desert

In geography, a desert is a landscape form or region that receives very little precipitation. Generally deserts are defined as areas that receive an average annual precipitation of less than 250 mm (10 inches). The terminology used to define deserts is complex.

12

Typhoon

typhoon. ty·phoon. Use typhoon in a sentence. noun. The definition of a typhoon is a tropical cyclone with winds faster than 74 miles per hour that occurs in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, the South Pacific east of 160E and the Northwest Pacific Ocean west of the date line.

13

Humidity

atmospheric moisture.

14

Forecast

Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. Human beings have attempted to predict the weather informally for millennia and formally since the 19th century. ... There are a variety of end uses to weather forecasts.

15

Atmosphere

the envelope of gases surrounding the earth or another planet.

16

Hail

the envelope of gases surrounding the earth or another planet.

17

Thunderstorm

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

18

Cloud

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

19

Precipitation

the action or process of precipitating a substance from a solution.

20

Drought

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

21

Front

the side or part of an object that presents itself to view or that is normally seen or used first; the most forward part of something.

22

Meteorology

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

23

Freezing point

the temperature at which a liquid turns into a solid when cooled. Under 32 degrees

24

Tornado

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

25

Cumulus cloud

Cumulus clouds are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile. ... Cumulus clouds may appear by themselves, in lines, or in clusters.

26

Thunder

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

27

Weather

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

28

Waterspout

a rotating column of water and spray formed by a whirlwind occurring over the sea or other body of water.

29

Barometer

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

30

Global warming

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.

31

Temperature

the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

32

Barometric pressure

another term for atmospheric pressure.

33

Funnel cloud

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

34

Climate

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