Fog on the central California coast for 1973 : analysis of trends

Abstract

Surface visibility data for selected stations on the central California coast in 1973 are analyzed. Radiosonde data from Oakland for the same period are used to derive meteorological indices. The year is divided into fog-related seasons, summer and winter, based on fog occurrence on the coast; and the seasonal and daily fluctuations of the indices are examined. A fog development model for the summer is formulated and compared to actual fog cases. In the winter, with far fewer coastal fog observations, the frequent occurrence of frontal passages prevents a standard development model from being formulated and compared. Four Oakland soundings are compared with four radiosondes taken at NPS Monterey, and the Oakland soundings are found to closely / approximate coastal conditions on these days.

Fog on the U.S. West Coast: A Review

“…This sequence turns out to be almost identical to the sequence of events observed in fog developments off the California coast. 9) WHEELER (1974) TO BACKES (1977) Within this period, six Naval Postgraduate School theses by Leipper students Wheeler (1974), Misciasci (1974), Peterson (1975), Evermann (1976), Beardsley (1976), and Backes (1977) were on the subject of West Coast fog. Of four other Naval Postgraduate School students working on fog projects, McConnell (1975), Koziara et al (1983), and Renard and Willms (1975) were advised by Professor Renard, and McClure (1974) was Professor Taylor's student.…”

“…For practical utilization of the phases see Leipper (1980a). The most informative onshore data collections are Peterson (1975), Beardsley (1976), and Leipper (1948bLeipper ( , 1968. The most useful offshore data are reported by Pelie et al (1979), Meneely and Merritt (1973), Leipper et al (1979), and Backes (1977).…”

Marine fog development along the west coast during 1973 using transient ship and coastal station observations

“…The objectives of this study are: (1) to examine the offshore atmospheric conditions relating to the formation and termination of marine fog along the central California coast for calendar year 1973 using available transient ship observations, and selected synoptic meteorological products; (2) to determine if the data from weather facilities along the coast can successfully be applied to a proposed marine fog model to determine the extent of coastal influence and to forecast fog-related conditions offshore; and (3) to establish the credibility and sufficiency of transient ship observations used in the synoptic approach to this study.…”
