Thick Fog Over California’s Great Central Valley – February 3rd, 201138.2N 121.3W
California’s Great Central Valley is covered by a thick layer of clouds. The clouds are resting over the valley, contained by the Cascade Range, Trinity Alps and Klamath Mountains to the north, the Sierra Nevada to the east, the Coast Ranges to the west, and the Tehachapi Mountains to the south.
Thick clouds can also be seen hanging over the Pacific Ocean, a common occurrence in the area due to a combination of atmospheric and oceanographic conditions. The dense white lines through the clouds are ship tracks, clouds formed around the exhaust released by passing ships.
