| 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 |
