Rate of decrease of an air temperature (static air) with elevationCurrent LectureII. Chapter 6- Stability and Cloud developmentA. What is adiabatic process?- Rising in air parcel EXPANDS- Expansion is due to decrease of pressure with altitude- Expanded rising air COOLSB. Adiabatic cooling- Cooling that is taking place within the air parcel without losing its heat to surroundingsC. Adiabatic warming- Compressed sinking air warms- Warming takes place within the parcel without drawing heat from the surroundings D. Adiabatic process- Expanding and cooling or compressing and warming of air with no interchange ofheat with its surroundingsE. Adiabatic rates- Every 1000 feet temperature drops a certain amount (constant)- Dry adiabatic rate (DALR)- Moist adiabatic rate (MALR)F. Dry adiabatic lapse rate:- Rate of change in temperature in a rising or descending unsaturated air parcel only 15.5° F/1000 feetG. Moist adiabatic lapse rate- Rate of change in temperature in a rising or descending saturated air parcel- Varies- but always less than 5.5°F/1000 feetH. Non-Adiabatic rates- Environmental lapse rateI. Rate of decrease of an air temperature (static air) with elevation- 3.5°F/1000 feet- Dew point lapse rate- Rate of change of dew point temperature 1°F/1000
