Unit 6 - Weather Prediction

Front 1

Thermometer

Back 1

An instrument that measures temperature in degrees Fahrenheit (F) or Celsius (C)

Front 2

Barometer

Back 2

An instrument that measures air pressure in millibars (mb) or inches of mercury

Front 3

Anemometer

Back 3

An instrument that measures wind speed in miles per hour (mph)

Front 4

Wind Vane

Back 4

An instrument that measures wind direction

Front 5

Sling Psychrometer

Back 5

A type of hygrometer that uses a wet-bulb and dry-bulb thermometer to measure relative humidity

Front 6

Relative Humidity

Back 6

A percentage that tells you how full of water vapor the air is; high relative humidity causes evaporation to slow down

Front 7

Hygrometer

Back 7

An instrument that measures relative humidity

Front 8

Meteorologist

Back 8

Scientist that studies the weather and uses information from Doppler radar, weather satellites, computers, and other weather instruments to make weather maps and forecasts

Front 9

Isobar

Back 9

Lines on a map that join areas of similar air pressure;
the closer together the lines, the stronger the wind

Front 10

Isotherm

Back 10

Lines on a map that join areas of similar temperature

Front 11

Weather Map

Back 11

A diagram that shows information gathered from station models, satellites, and radar that is used to forecast weather.

Front 12

Satellite

Back 12

A device that orbits earth and is used to detect cloud patterns and movement; useful for detecting fronts and for tracking the movement of hurricanes.

Front 13

Radar

Back 13

Can be used to detect cloud cover, rainfall or storm location, intensity, and movement, as well as the potential for severe weather

Front 14

High Pressure System

Back 14

Winds move clockwise around this system; brings fair weather

Front 15

Low Pressure System

Back 15

Winds move counterclockwise around this system; brings storms

Front 16

Air Mass

Back 16

Huge clump of air with similar temperature and amount of water vapor

Front 17

Front

Back 17

When different air masses collide and do not mix

Front 18

Warm Front

Back 18

Forms when warm air slowly slides over a cold air mass; produces long periods of rain and warmer temperatures

Front 19

Cold Front

Back 19

Forms when a cold air mass rapidly pushes a warm air mass up and out of the way; produces storms and cool temperatures

Front 20

Occluded Front

Back 20

When a warm air mass is completely cut off from the ground by two cooler air masses; produces long periods of rain

Front 21

Stationary Front

Back 21

When a cold and warm air mass collide and neither one moves; produces long periods of rain

Front 22

Thunderstorm

Back 22

Storm with thunder, lightning, heavy rains and strong winds; form within large cumulonimbus clouds in areas of low pressure

Front 23

Hurricane

Back 23

A low pressure tropical storm that forms over warm ocean water; winds form a spinning circular pattern around the center, or eye, of the storm

Front 24

Tornado

Back 24

A rapidly whirling, funnel-shaped cloud that extends down from a cumulonimbus cloud

Front 25

Station Model

Back 25

Indicates weather conditions at a specific location and time, using a combination of symbols and numbers

Front 26

Cumulus

Back 26

Large, thick, puffy white clouds that are found at low elevations and indicate fair weather

Front 27

Stratus

Back 27

Spread out layer on layer, flat gray clouds that are found at low elevations and indicate steady rain

Front 28

Cirrus

Back 28

Thin, wispy clouds made mostly of ice crystals that are found at high elevations and indicate fair weather or approaching warm fronts

Front 29

Fog

Back 29

A type of stratus cloud that forms at ground level

Front 30

Cumulonimbus

Back 30

Tall, towering cloud that often brings thunderstorms

Front 31

-Nimbus/Nimbo-

Back 31

Used in the names of clouds that produce precipitation; means "rain"

Front 32

Alto

Back 32

Used in the names of clouds that are found at medium elevations
