: the rate at which the temperature of an ascending or descending body of air is changed by adiabatic expansion or compression, being about 1.6° F. for each 300 feet of change of height; also : a curve representing this
* * *adiabatic gradient or adiabatic rate,the rate at which a parcel of air becomes cooler or warmer as it gains or loses altitude, respectively, estimated to be approximately 5.5 degrees Fahrenheit per 1,000 feet, or 1 degree centigrade (Celsius) per 100 meters.
