Question | Answer |
---|---|
Upslope Fog | formed by lifting and adiabitic cooling of air as it rises along land slopes |
Supercooling | process in which water droplets are inducded to remain liquid a temperatures below 0 |
Sublimation | process in which a solid changes directly into a vapor |
Stratus Cloud | Cloud with a sheetlike or layered form, look like they cover the horizon |
Steam Fog | Condensation of water vapor that results when cool air moves over warm air, usually forms over rivers |
Specific Humidity | Exact amount of moisture (water vapor) in the air |
Sleet | Ice pellets that form when rain falls through a layer of freezing air |
Saturated | describing air that contains all the water vapor it can hold at a specific temperature |
Relative Humidity | ratio of the amount of wate4r vapor the air can hold when saturated, measured by percent |
Rain Gauge | instrument used to measure the amount of rainfall |
Radiation Fog | condensation of water vapor that results from the cooling of air that is in contact with the ground |
Psychrometer | instrument used to measure relative humidity |
Latent Heat | energy stored in molecules |
Humidity | amount of water vapor in the atmosphere |
Hair Hydrometer | instrument used to measure relative humidity based on the fact that human hair stretches as humidity increases |
Hail | type of precipation in the form of lumps of ice |
Freezing Nuclei | condensation nuclei with a crystalline structure like that of ice |
Glaze Ice | thick layer of sheet ice formed when rain freezes as it contacts a surfeace |
Frost | ice crystals formed when the dew point is below 0 degrees and water vapor directly enters the solid state |
Dew Point | temperature to which air must be cooled to become saturated |
Dew | type of condensation formed when air that is in contact with a cool surface loses heat until it reaches saturation |
Cumulus Cloud | thick, billowy,white, fluffy clouds |
Convective Cooling | decrease in temperature of a mass of air that results as the air rises and expands |
Condensation Nuclei | solid particles in the atmosphere, such as ice&dust, that provide the surfaces on which water vapor condenses |
Coalescene | combination of different sized cloud droplets to form larger droplets |
Cloud Seeding | addition of freezing nuclei to super cooled clouds in attempt to induce or increase precipitation |
Cirrus Cloud | feathery cloud composed of ice crystals, high in the sky, thin |
Advective Cooling | decrease in temperature of a mass of air that results as it moves over a cold surface |
Advection Fog | condensation of water vapor that results from the cooling of warm, moist air as it moves across a cold surface |
Adiabatic | describing a change in temperature resulting from the expansion or compression of air |
