Lower fog levels are also problematic for the agricultural regions fog patterns support, such as the Napa and Salinas Valleys. [14] Not only has the fog season shortened, lasting from June to September instead of from May to October, but the hours per day there is fog has shortened by about three hours.
A summer fog for fair, A winter fog for rain. A fact most everywhere, In valley or on plain. Fog is formed when the air cools enough that the vapour pressure encourages condensation over evaporation. In order for the air to be cool on a summer night, the sky must be clear, so excess heat can be radiated into space. Cloudy skies act like a ...
Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.

Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
Dense fog recently contributed to a deadly, multiple-vehicle pileup in China. In New York City, poor visibility led to a ground stop at LaGuardia Airport on Saturday morning.
Another way fog forms in deserts occurs when a desert is close to an ocean which has a cold current. When air is heated over desert land and blows towards the cool water in the ocean, it condenses and fog is formed. The cool fog is then blown inland by the ocean breeze. Fog is mainly formed in the early morning or after sunset. [5]
