GEOG 101 Lecture Notes - Lecture 9: Atmospheric Sounding, Evaporation, Cool Air
Document Summary
The temp of air changes without the addition or removal of heat. Air rises = expansion = air particle moving air = release of heat. Air moving down = greater density pushing on it = transfers heat from air doing work to air that is being affected. A reflection of temperature in the atmosphere with elevation. The temperature of the air at any particular elevation of the surface. To be determine from atmospheric sounding. Dry adiabatic lapse rate (dar or dalr) A dry parcel of air (i. e. no condensation) cools as it rises at approx 10. 0 degrees celsius per 1000m. Moist adiabatic lapse rate (mar or malr) When moist air ascends, it may research a point when some of the water vapor condenses (dew point and saturation vapor pressure is reached) The lapse rate is approximately 0. 6 degrees celsius per 1000m. Why is moist 0. 6 degrees celsius per 1000m, and dry 10. 0 degrees celsius per.
