Assume a warm air parcel,at sea level,has a temperature of 21 °C (70°F)and begins to rise upward.Assume it becomes saturated at 1000 m (3300 ft)altitude,and continues to rise to 2000 m (6600 ft.)altitude.What would the approximate temperature of the parcel be at an elevation of 2000 m (6600 ft.)?

Question

Quizplus · Accepted Answer

As the air parcel rises, it cools at the dry adiabatic lapse rate of about 10°C per 1000 m until it reaches saturation at 1000 m. From there, it cools at the moist adiabatic lapse rate of about 5°C per 1000 m. Starting at 21°C at sea level, it cools to 11°C at 1000 m, and then to approximately 6°C at 2000 m.
