10/4 Moisture - Moisture: water exists in three phases Vapor, liquid, solid - Energy is absorbed and given off when changing phases A. Processes where heat absorbed by a substance and taken away from environment - Melting: solid to liquid - Evaporation: liquid to vapor - Sublimation: solid to vapor B. Processes where energy is given up by a substance and added to the environment - Condensation: liquid to solid - Freezing: liquid to solid - Deposition: vapor to solid I. Moisture variables a. Dew point temperature: temperature at which you cool air, saturation will occur b. Wet bulb temperature: lowest temp obtained by evaporating water to the air c. Vapor pressure: part of atmosphere pressure attributed to water vapor

Unformatted text preview: d. Saturated vapor pressure: when air is saturated at a specific temperature e. Mixing ratio: actual amount of water vapor in a parcel of air f. Saturated mixing ratio: saturated air at a specific temp II. Relative Humidity: ratio of amount of vapor actually in the air compared to the max amount required for saturation at that given temp III. Hydrophobic Particles: no affinity IV. Hydroscopic particles: particles with a special affinity for converting water vapor to liquid drops V. Adiabatic process: without the transfer of heat VI. Diabatic process: heat is added or removed from the air...
