When the environmental lapse rate exceeds both the dry adiabatic lapse rate and the wet adiabatic lapse rate of a parcel of air,that air parcel contains:
A)absolutely stable air.
B)conditionally unstable air.
C)absolutely unstable air.
D)air that cannot reach the lifting condensation level.

Question

Quizplus · Accepted Answer

When the environmental lapse rate exceeds both the dry and wet adiabatic lapse rates, it means the surrounding air temperature decreases with altitude faster than the air parcel cools as it rises. This condition promotes continued rising and expansion of the air parcel, indicating absolutely unstable air.
