Tanio_SJV_setting
ntanioThe setting for this article is the San Joaquin Valley which encompasses 2/3rds of the Central Valley CA. Because of it's fertle farmland, it supplies 1/4 of the food to "American plates."
In terms of setting, like other valley's in CA (ex: San Gabriel Valley) and the whole LA Basin, the SJV's bowl-like landscape (mountain ranges on 3-sides) results in temperature inversion that traps smo closer to the ground during Wintertime.
