Question | Answer |
Air Mass | Large body of air with uniform temperature and moisture content |
Anemometer | Instrument used to measure wind speed |
Anticyclone | Storm that spirals outward from a high-pressure center |
Bimetal Thermometer | Instrument used to measure temperature, consisting of a bar made of two strips of different metals that curves when heated and straightens when cooled |
Cold Front | Boundary formed where a cold air mass overtakes and lifts a warm air mass |
Continental Polar | Describing a cold, dry air mass that forms over land in polar regions |
Continental Tropical | Describing a warm, dry air mass that forms over land in tropical regions |
Electrical Thermometer | Instrument used to measure temperature based on the increased flow of electricity through certain materials when the materials are heated |
Front | Boundary between air masses of different densities |
Hurricane | Severe storm that develops over tropical oceans, with strong winds that spiral in toward the intensely low-pressure storm center |
Isobar | Line drawn on a weather map connecting points of equal atmospheric pressure |
Maritime Polar | Describing a cold, moist air mass that forms over the ocean in polar areas |
Maritime Tropical | Describing a warm, moist air mass that forms over the ocean in tropical areas |
Occluded Front | Boundary formed where a fast moving cold air mass overtakes and lifts a warm air mass, completely cutting it off from the ground |
Polar Front | Boundary at which cold polar air meets the warmer air of the middle latitudes |
Radar | Device that can detect objects and weather conditions in the upper atmosphere by sending and reciving radio waves |
Squall line | Long line of heavy thunderstorms that may occur just ahead of a fast-moving cold front |
Station Model | Cluster of weather symbols plotted on a map indicating the weather conditions at a particular reporting station |
Stationary Front | Boundary formed where two air masses meet and neither is displaced |
Thermograph | Instrument that measures temperature changes by recording the movement of the bar of a bimetal thermometer |
Thunderstorm | Storm accompanied by thunder, lightning, and strong winds |
Tornado | Whirling, funnel-shaped cyclone |
Typhoon | Hurricane that forms over the Pacific Ocean |
Warm Front | Boundary formed where a warm air mass overtakes and rises over a cold air mass |
Waterspout | Tornado that occurs over the ocean |
Wave Cyclone | Large storm that develops along cold or stationary fronts, with winds that spiral in toward a central region of low air pressure |
Wind Vane | Instrument used to determine the direction of the wind |
