lapse rate

lapse rate
The rate of decrease of an atmospheric variable with height. However, the term normally refers to the fall of temperature with height. The three types of lapse rates referred to in meteorology are dry adiabatic lapse rate, saturated adiabatic lapse rate, and environmental lapse rate. See also dry adiabatic lapse rate, saturated adiabatic lapse rate, and environmental lapse rate.
