Extreme tides and sea levels in California [abstract]

During the winter of 1982-1983, a combination of high tides, higher than normal sea level and storm-induced waves were devastating to the coast of California. Damage estimates for public and private property destruction in the coastal counties of California totaled over $100,000,000.Much higher than average sea levels played a very important contributory role in the flooding damage. These unusually high sea levels were due to a combination of higher than normal mixed layer temperature associated with a strong, 2-year El Nino, storm surge due to low atmospheric pressure and persistent winds, and the cumulative effect of steady, "global" rise in relative sea level.Higher than average high tides coincided to an unusual extent with the peak sea levels reached during the numerous storms between November 1982 and March 1983. Important cyclical variations occur in California's mixed tide regime and the consequences of these on extreme tides have not been properly considered previously. In fact, erroneous "predictions" of much higher tides in the 1990's appearing in the popular press during the 1982-83 flooding, caused much public apprehension.
