The cumulonimbus cloud pictured in Figure \(17.21 \mathrm{H}\) is roughly 12 kilometers tall, 8 kilometers wide, and 8 kilometers long. Assume that the droplets in each cubic meter of the cloud total 0.5 cubic centimeter. How much liquid does the cloud contain? How many gallons is this? (Note: \(3785 \mathrm{~cm}^{3}=1\) gallon.)

Why does radiation fog form mainly on clear nights rather than on cloudy nights?

What are the advantages and disadvantages of using rain gauges compared to weather radar in measuring rainfall?
