Winter Fog Becoming Rare in California

From time to time, in the wake of winter rain, dense fog fills the wide valley between California’s Sierra Nevada and Coastal Range. Called Tule fog, the phenomenon is as much a part of winter in the Central Valley as snow is in the mountain. In recent years, however, the fog has come less often. In fact, since 1981 the number of fog days between November and February has decreased by 46 percent, according to a recent study. The decrease is bad news for California’s fruit and nut farmers.

This image, acquired on January 17, 2011, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, shows one of the more recent valley fog events. (Drought has limited the number of fog events since 2012.) University of California–Berkeley researchers Dennis Baldocchi and Eric Waller used images from MODIS and from NOAA’s advanced very high resolution radiometer (AVHRR) to count the number of fog days since 1981. They found a downward trend. Read more
