- 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.

moist adiabatic rate — The rate of cooling of ascending saturated air. It is approximately 1.5°C/1000 ft but may reduce to as little as 1°C/1000 ft in the warm saturated tropical regions and may exceed 2°C/1000 ft when the temperature of the air falls below the… … Aviation dictionary
