Question 0

At approximately what altitude above the surface would the pilot expect the base of the cumuliform clouds if the surface air temp is 82 degrees F, and the dew point is 38 degrees F?

Answer 0

10,000 feet

82 - 38 = 44
44 / 4.4 x 1000 ft = 10,000

Question 1

What is the appropriate base of the cumulus clouds if the surface air temperature at 1,000 feet MSL is 70 degrees F, and the dew point is 48 degrees F?

Answer 1

6,000 feet

Clouds will form when the temp and dew point meet. The temp and dew point get closer together with altitude, at the rate of 4.4 deg F per 1,000 feet. Since the altitude is, 1000 feet MSL, by adding 5000 feet, we would find cloud bases at 6,000 feet.
