---|---|
LATENT HEAT | The heat energy that is absorbed or released by a substance during a phase change |
SUBLIMATION | The process by which a solid changes directly into a gas |
DEW POINT | The temperature at which the condensation rate equals the evaporation rate |
ABSOLUTE HUMIDITY | the mass of water vapor contained in a given volume of air |
RELATIVE HUMIDITY | ratio of the actual water vapor content of the air to the amount of water vapor needed to reach saturation |
CLOUD | collection of small water droplets or ice crystals in the air |
CONDENSATION NUCLES | The suspended particles that provide the surfaces necessary for water vapor to condense |
ADIABATIC COOLING | The process by which the temperature of a mass of air decreases as the air rises and expands |
ADVECTIVE COOLING | process by which the temperature of an air mass decreases as the air mass moves over a cold surface, such as a cold ocean or land surface |
STRATUS CLOUD | Clouds that have a flat, uniform base and that begin to form at very low altitudes |
CUMULUS CLOUD | Low-altitude, billowy clouds that commonly have a top that resembles cotton balls and a dark bottom |
CIRRUS CLOUD | Feathery clouds that are composed of ice crystals and that have the highest altitude of any cloud in the sky |
FOG | result of the condensation of water vapor in the air |
