what is the dry adiabatic lapse rate
If that parcel descends again to higher pressure, its temperature then INCREASES at the rate of 1Â°C per 100 meters or 5 1/2Â°F per 1,000 feet. This is known as the dry adiabatic lapse rate. MOIST (SATURATION) ADIABATIC LAPSE RATE.When a mass of air is lifted, it cools at the dry adiabatic lapse rate of 5 1/2Â°F per 1,000 feet as long as it remains unsaturated (relative humidity below 100 percent).
