Flashcards in Weather Deck (34):
1

Air pressure

the force that air puts on an area (related word: pressure)

2

Tropical Depression

a region of low pressure with counter-clockwise wind rotation that develops into a hurricane or tropical storm

3

Celsius

the metric temperature scale: Water boils at 100 degrees Celsius, and it freezes at 0 degrees Celsius.

4

Cumulus Cloud

large, fluffy, white clouds, often seen in fair skies; can develop into cumulonimbus clouds

5

Cirrus Cloud

thin, wispy-looking clouds; commonly found at heights greater than 6 km

6

Thermometer

a device used to measure temperature

7

Tropical

describing a climate that is very hot and humid; describing an area of Earth that is near the equator

8

Ocean Current

large-scale movement of water within the oceans in a certain direction

9

Dew Point

the temperature at which water vapor in the air condenses into water

10

Hurricane

a storm with strong winds and rain that forms over tropical waters (related term: typhoon, tropical cyclone)

11

Desert

an area that gets little precipitation and has very little vegetation

12

Typhoon

a hurricane or tropical storm originating in the Pacific Ocean

13

Humidity

the measure of how much water vapor is in the air

14

Forecast

Definition
(v) to analyze weather data and make an educated guess about weather in the future; (n) a prediction about what the weather will be like in the future based on weather data

15

Atmosphere

layers of gas that surround a planet (related word: atmospheric)

16

Hail

small, icy balls that fall from the sky

17

Thunderstorm

a weather system that produces heavy precipitation, winds, lightning, and thunder

18

Cloud

a collection of water droplets or ice crystals in the atmosphere

19

Precipitation

water that is released from clouds in the sky; includes rain, snow, sleet, hail, and freezing rain

20

Drought

a prolonged shortage of rainfall

21

Front

in weather, the boundary between two masses of air with different properties

22

Meteorology

the study of patterns of weather

23

Freezing Point

the temperature at which a liquid turns into a solid

24

Tornado

a funnel-shaped cloud or column of air that rotates at high speeds and extends downward from a cloud to the ground

25

Cumulonimbus Cloud

anvil-shaped cloud that is often involved in heavy or violent storms: Cumulonimbus clouds are also called thunderheads. (related words: cumulus, nimbus)

26

Thunder

a loud noise that happens when lightning heats the air and causes it to expand and contract quickly

27

Weather

the properties of the atmosphere at a given time and location, including temperature, air movement and precipitation

28

Waterspout

a funnel-shaped cloud that forms over water and pulls water upward

29

Barometer

a tool used to measure air pressure (related word: barometric)

30

Global Warming

the slow warming of Earth's atmosphere due to climatic change

31

Temperature

a measure of the average kinetic energy of the atoms in a system, used to express thermal energy in degrees

32

Barometric Pressure

the pressure (force per unit area) of the atmosphere against a surface

33

Funnel Cloud

a rotating, funnel-shaped cloud: Funnel clouds do not touch the ground.

34

Climate

the current or past long-term weather conditions characteristic of a region or the entire Earth.

the average weather conditions in an area (related word: climatic)
