This is known as the dry adiabatic lapse rate. Saturation Adiabatic Lapse Rate When a mass of air is lifted, it cools at a practically constant rate of 51/2° F per 1,000 feet as long as it remains unsaturated (relative humidity below 100 percent). If the original moisture is being carried along with the mass as it ascends, it cools to its saturation temperature, and the relative humidity is then 100 percent. Condensation takes place with any further cooling. For each gram of water con- densed, about 597 calories of heat are liberated. This latent heat of condensation is absorbed by the air, and the adiabatic cooling rate is decreased to 2° to 3° F per 1,000 feet instead of 5 1/2° F per 1,000 feet. The process during the saturated expansion of the air is called the saturation adiabatic, the moist adiabatic, or the pseudoadiabatic process. Thepseudoadiabatic process assumes that moisture falls out of the air as soon as it condenses. How the temperature of a parcel of air changes in response to these processes can be 275.
