Although it focuses on the western part of the United States, this is one of the best books on weather that I have read and the information is applicable to everywhere in the U.S. The book starts with the causes of weather and covers everything from the effect of an atmosphere and the warming of it by the sun to the effect of the earth’s rotation, moisture, land masses, etc. After that base for understanding weather they move into the specifics of weather phenomenon like fronts, jets, cyclones, snow, rain, thunderstorms, hurricanes, whirlwinds, and lights in the sky.
