| Question | Answer |
|---|---|
| adiabatic | describing a change in temperature resulting from the cooling of rising air and the warming of sinking air |
| advection fog | condensation of water vapor that results from the cooling of warm, moist air as it moves across a cold surface |
| advective cooling | decrease in the temperature of a mass of air that results as it moves over a cold surface |
| cirrus cloud | feathery cloud composed of ice crystals that has the highest altitude of any cloud in the sky |
| cloud seeding | addition of freezing nuclei to supercooled clouds in an attempt to induce or increase precipitation |
| coalescence | combination of different-sized cloud droplets to form larger droplets |
| condensation nuclei | solid particles in the atmosphere, such as ice and dust, that provide the surfaces on which water vapor condenses |
| convective cooling | decrease in the temperature of a mass of air that results as the air rises and expands |
| cumulus cloud | thick, billowy cloud that forms above stratus clouds and below cirrus clouds |
| dew | type of condensation formed when air that is in contact with a cool surface loses heat until it reaches saturation |
| dew point | temperature to which air must be cooled to become saturated |
| freezing nuclei | condensation nuclei with a crystalline structure like that of ice |
| frost | ice crystals formed when the dew point is below 0 degrees Celsius and water vapor directly enters the solid state |
| glaze ice | thick layer of sheet ice formed when rain freezes as it contacts a surface |
| hail | type of precipitation in the form of lumps of ice |
| hair hygrometer | instrument used to measure relative humidity, based on the fact that human hair stretches as humidity increases |
| humidity | amount of water vapor in the atmosphere |
| latent heat | energy stored in molecules |
| psychrometer | instrument used to measure relative humidity |
| radiation fog | condensation of water vapor that results from the cooling of air that is in contact with the ground |
| rain gauge | instrument used to measure the amount of rainfall |
| relative humidity | ratio of the amount of water vapor in the air to the amount of water vapor the air can hold when saturated |
| saturated | describing air that contains all the water vapor it can hold at a specific temperature |
| sleet | ice pellets that form when rain falls through a layer of freezing air |
| specific humidity | actual amount of moisture in the air |
| steam fog | condensation of water vapor that results when cool air moves over warm water |
| stratus cloud | cloud with a sheetlike or layered form that is the lowest cloud in the sky |
| sublimation | process in which a solid changes directly into a gas, or a gas changes directly into a solid |
| supercooling | process in which water droplets are induced to remain liquid at temperatures below 0 degrees Celsius |
| upslope fog | condensation of water vapor that results from the lifting and adiabatic cooling of air rising up a slope of land |
