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. It also may exceed 2°C/1000 ft when the temperature of the air falls below the freezing point until it is no longer saturated and the lapse rate falls to that of dry air.
