Weather and Climate Blog Post #2

Stockton, CA is affected by three main air masses.  During the summer Maritime Tropic air is most prominent and during the winter months Maritime Polar and Continental Polar affect the region.  This area experiences its mid-latitude cyclones during the winter months with the Maritime Polar air occluding with warmer fronts.  The summer months on the other hand are very boring and little to know precipitation or temperature variance is seen.  The summers are filled with hot dry days and mild to cool evenings and nights.

Tule fog is 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 for an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.Tule fog forms from late autumn through early spring after the first significant rainfall. The official time frame for tule fog to form is from November 1 to March 31. This phenomenon is named after the tule grass wetlands of the Central Valley. Motor vehicle accidents caused by the tule fog are the leading cause of weather-related casualties in California. (wikipedia.org)

Another weather phenomenon..the Pineapple Express affects California as well.  Pineapple Express is a non-technical term for a meteorological phenomenon characterized by a strong and persistent flow of atmospheric moisture and associated with heavy precipitation from the waters adjacent to the Hawaiian Islands and extending to any location along the Pacific coast of North America. A Pineapple Express is an example of an atmospheric river, which is a more general term for such narrow corridors of enhanced water vapor transport at mid-latitudes around the world.

Finally, Inversion is commonly seen in and around Stockton, CA.  This is beneficial to the agricultural setting in the area.  Late day warming gives certain crops an extra boost before the sun creeps behind the mountains.
