Back 2

instrument used to measure wind speed.

Front 3

Anticyclone

Back 3

strorm that centers outward form a high pressure center.

Front 4

Bimetal thermometer

Back 4

instrument used to measure temperature, consisting of a bar made up of two strips of differnet metals that curves when heated and straightens when cooled.

Front 5

Cold Front

Back 5

boundary formed where a cold air mass overtakes and lifts a warm air mass.

Front 6

Continental Polar

Back 6

Describing a cold, dry air mass that forms over land in polar regions.

Front 7

Continental Tropical

Back 7

Describing a cold, dry air mass that forms over land in tropical regions.

Front 8

Electric Thermometer

Back 8

instrument used to measure temperature based on the increased flow of electricity through certain materials when the materials are heated.

Front 9

Front

Back 9

boundary between air masses of differnet densities.

Front 10

Hurricane

Back 10

severe storm that develops over tropical oceans, with strong winds that spiral in toward the intensely low-pressure storm center.

Front 11

Isobar

Back 11

Line drawn on a weather map connecting points of equal atmospheric pressure.

Front 12

Maritime Polar

Back 12

Describing a cold, moist air mass that is formed over the ocean in polar areas.

Front 13

Maritime Tropical

Back 13

Describing a cold, moist air mass that is formed over the ocena in tropical areas.

Front 14

Occluded Front

Back 14

boundary formed where a fast-moving cold air mass overtakes and lifts a warm air mass, completely cutting it off from the ground.

Front 15

Polar Front

Back 15

boundary at which cold polar air meets the warmer air of the middle latitudes.

Front 16

Radar

Back 16

Device that can detect objects and weather conditions in the upper atmosphere by sending and receiving radio waves.

Front 17

Squall Line

Back 17

Long line of heavy thuderstorms that may occur just ahead of a fast-moving cold front.

Front 18

Station Model

Back 18

cluster of weather symbols plotted on on a map indicating the weather conditions at a particular reporting station.

Front 19

Stationary Front

Back 19

boundary formed where two air masses meet and neither is displaced.

Front 20

Thermograph

Back 20

instrument that measures temperature changes by recording the movement of the bar of a bimetal thermometer.

Back 22

whirling, funnel-shaped cyclone.

Front 23

Typhoon

Back 23

hurricane that forms over the Pacific Ocean.

Front 24

Warm Front

Back 24

boundary formed where a warm air mass overtakes and rises over a cold air mass.

Front 25

Waterspout

Back 25

tornado that occurs over the ocean.

Front 26

Wave cyclone

Back 26

large storm the develops along cold or stationary fronts, with winds that spiral in toward a central region of low air pressure.

Front 27

Wind Vane

Back 27

instrument used to determine the direction of the wind.
