Air Pressure-pressure(weight, force) of air overhead Anemometer-instrument used to measure wind speed and direction Atmosphere-gases that surround the earth Cirrus-streak clouds 4-6 miles above ground Cold front-edge of cold air mass, next to and beneath a warm air mass
Condensation-act of condensing-ex:reduction gas to liquid
Cumulus-fluffy piles cotton clouds, 1-4 miles high
Dew-condensation formed,result warm air contacting a cool surface
Dew point-temperature at which cooling air becomes saturated and dew forms
Evaporation-change from moisture to water vapor Eye of the storm-center of storm-calm(good weather), before second
part of storm
Frost-icy crystals that form directly on a freezing surface
Hazardous-of or involving chance
High-area of high pressure located at the center of an air mass, usually meaning fair weather
Hurricane-violent tropical cyclone, winds 73
Hygrometer-instrument to measure humidity
Low-area of low air pressure-frontal low when happening along a front-usualy means change in weather
Mean temperature-average temperature over a period of time
Mist-large mass of water vapor at or above earth’s surface, resembles fog, but less dense
Northeaster-storm or strong wind from the northeast
Precipitation-depositing of rain, snow, sleet, etc.
Saturation-point at which a substance can absorb nothing more
Stationary front-front that is stalled , neither air mass is moving
Stratus-sheet clouds, low altitude, usually gray in color
Tornado-violently whirling column of air-speeds l60-480 km/hr extending downward from a cumulonimbus cloud. Rapidily rotating funnel shaped cloud
Troposphere-lowest layer of earth’s atmosphere, contains weather
Warm front-edge of a warm air mass advancing against a colder air mass
Wind-air in motion
