Aerial photo of tule fog blanket in the California Central Valley, prevalent during winter
months (December–February). The high humidity, calm winds, and rapid nighttime cooling
in the valley develops the tule fog. The long winter nights cool the ground and produce a temperature inversion at low altitudes. (Credit to Jeff Schmaltz, National Aeronautics and Space
