Question | Answer |
---|---|
Air Mass | large body of air whose temperature and amount of moisture depends on the surface (Earth) over which it developed |
Dew Point | temperature in which water vapor in saturated air begins to condense |
Front | boundary resulting from the collision between moving air masses |
Front | produces weather events such as rain, snow, or violent storms (depending on type of air mass front meets) |
Hurricane | intense, highly destructive storm |
Hurricane | low pressure system over a warm, moist tropical ocean |
Hurricane | very high intense, high winds and possible torrential rains |
Hurricane | weakens when reaches land |
Saturated | 100 percent relative humidity of air |
Saturated | occurs when air cannot hold additional moisture at a specific temperature |
Tornado | violent, funnel-shaped storm from a low pressure system |
Tornado | highly destructive,short-lasting, moves over land in narrow path |
Wind | moving air |
Torrential Rain | air pouring or flowing fast, violently or heavily |
Weather Forecaster | a person who predicts the weather |
Weather Forecast | prediction of the weather |
Station Model | symbolic illustration showing weather occurring at a given weather station |
Cloud Seeding | method used to make a cloud give up moisture |
Occluded | to force air upward from Earth’s surface |
Occluded | when a cold front overtakes and undercuts a warm front |
Barometric Pressure | pressure exerted by Earth’s atmosphere at any given point |
Nimbus | dark-grey, rain-bearing cloud |
Stratus | cloud with gray, horizontal layer with uniform base |
Cumulus | dense, white, fluffy, flat-based cloud with multiple rounded top and well defined outline |
Cirrus | thin, wispy, fibrous cloud at high altitudes; made of ice particles |
