CA Notable Severe Weather Events

California´ Weather History

" The principal source of precipitation in California is moisture laden marine air moving in from the Pacific Ocean. The storm systems that deliver the moisture generally originate in the Gulf of Alaska and occasionally in the eastern Pacific Ocean. A semi-permanent high-pressure system located off the State's coast tends to regulate the movement of Pacific storms and is a key feature of the atmospheric-circulation patterns that determine California's climate (Officials of the National Oceanic and Atmospheric Administration, 1974). The position of this high-pressure system affects the seasonal distribution of precipitation and the erratic multiyear periods of greater than normal or less than normal precipitation. The geographic distribution and intensity of precipitation are determined by the Pacific storm track in combination with the State's topography. "

" Precipitation is rare during the summer. The Pacific high pressure area off the northern California coast keeps storm tracks well to the north. Occasionally, moist air moves in from the subtropical Pacific Ocean during the summer and results in scattered thundershowers that are sometimes locally intense in the deserts and mountains. "

" Most precipitation in California is received during the storm season from November to March. In winter, the Pacific high-pressure system generally moves southward, allowing storms from the Gulf of Alaska to move across California. These storms commonly are a series of frontal systems 2 or 3 days apart. Because of the usual pattern of storm movement, precipitation quantities are generally greatest in the north and progressively less toward the south. Variations in the circulation pattern at times cause storms to approach California from the southwest, thus bringing warm, moist air from the tropics. On occasion, when this inflow of air from the southwest converges with a contrasting flow of cold air from the Arctic, the results are devastating. The floods of December 1955, December 1964, and February 1986 were caused by storms of this type. If the Pacific high-pressure system fails to move south during the winter, winter storms are blocked, are diverted to the north of California, or are severely weakened. A persistence of this condition leads to drought in the State (California Department of Water Resources, 1978). "

" Mountain ranges induce precipitation at the higher altitudes and create "rain shadows" (dry areas) in the leeward valleys and plains. In California, nearly continuous ranges of coastal mountains extend from the Oregon border to Mexico, and these ranges are paralleled by the southern Cascade Range and the Sierra Nevada roughly 150 miles inland (fig. 1). Between the two ranges lies the Central Valley, nearly 400 miles long and 70 miles wide. To the east of the southern Cascade Range, the Sierra Nevada, and the coastal mountains of southern California are the Basin and Range and the Southern California Desert provinces. "

" The higher mountain areas, principally the Sierra Nevada, receive much of the annual precipitation as snow, which accumulates during winter and melts in spring; this important feature of California's hydrology provides a natural reservoir to moderate the uneven seasonal distribution of precipitation. Storage in the form of snow commonly decreases the severity of peak flows, but it also has contributed to some of the State's worst floods when warm rains melted the snow. Unusually large snow packs, like those in 1969, have caused flooding as a result of the large volume of runoff during the spring snowmelt. " [Ref] pp 198

"The droughts of 1928-37 and 1976-77 are the events to which other droughts commonly are compared. Both droughts were severe, and one or the other is cited by different sources as the worst in the State's recorded history. Because their durations were so different, comparisons between the two droughts are difficult, yet they illustrate the diversity of events characterized as droughts. The droughts of 1943-51 and 1959-62, although less severe, were relatively well defined and of statewide significance. The same is true of the current (1989) ongoing drought that began in 1987.[Ref]"
