If the environmental lapse rate is less than the wet adiabatic lapse rate, it means that the atmosphere is not capable of lifting an air parcel to its condensation level. This indicates that the air parcel will remain warmer than its surroundings and will continue to rise until it reaches an altitude where the temperature equals its own. Thus, the atmosphere is absolutely stable.
