Dry Adiabatic Lapse Rate The dry adiabatic lapse rate is one degree Celsius of cooling for every 100 meters (1°C/100m, 10°C/kilometer or 5.5°F/1000 feet). Thus a dry (simply not saturated) parcel of air that rises 200 meters will cool two degrees, when it descends 200 meters, it will regain its original temperature because its temperature will rise two degrees. As the parcel of air rises and it cools, it will eventually cool to the dew point when condensation can begin and clouds will form.
