This makes moist air generally less stable than dry air (see convective available potential energy [CAPE]). The dry adiabatic lapse rate (for unsaturated air) is  per 1,000 vertical feet (300 m). The moist adiabatic lapse rate varies from  per 1,000 vertical feet (300 m).
This shows that moist air tends to be less stable than dry air (as exemplified by convective available potential energy [CAPE]). The dry adiabatic cooling rate for unsaturated air is  per 1,000 vertical feet (300 meters). The moist adiabatic cooling rate varies from  per 1,000 vertical feet (300 meters).
