How does an air parcel cool
WebSep 29, 2024 · An air parcel will cool at the dry adiabatic lapse if it is lifted, remains unsaturated, and does not exchange energy or mass with its environment during lifting. What happens to the parcel of air as it descends? → The temperature of the air parcel (or balloon) decreases with elevation. WebJul 15, 2004 · Since the air parcel is now saturated, the air parcel will cool at the saturation adiabatic lapse rate (7 Celsius degrees per 1000 meters) over (2000 m - 500 m) = 1500 meters. In other words, the parcel cools by 10.5 Celsius degrees, meaning that 5 C - 10.5 C = -5.5 C. B.2 Dewpoint = -5.5 C
