Suppose the surface air temperature is 29C. If the base of a cumulus congestus cloud directly above you is 2000 metres, what is the approximate temperature at an altitude of 5000 metres inside the cloud? (Assume the dry adiabatic rate is 10C per 1000 metres, and the moist adiabatic rate is 6C per 1000 metres)
A)-13C
B)-9C
C)-8C
D)-5C

Quizplus · Accepted Answer

The temperature decreases by the dry adiabatic rate from the surface to the cloud base (2000m), and by the moist adiabatic rate from the cloud base to 5000m. Calculate the temperature at 5000m using these rates.
