Abstract:

Coastal fog studies have always alluded to offshore marine fog development by extending known observations along the coast seaward. This velocity study attempts to establish the offshore conditions during one such coastal fog study through the analysis of transient ship synoptic reports. Over 1400 ship reports occurring off the coasts of California, Oregon, and Washington during two weeks in August 1974 and one week in December 1975 were analyzed. The visibility-weather group elements of the ship reports along with daily NOAA II satellite photographs were used to establish fog location and boundaries. Other Synoptic parameters such as air temperature, pressure patterns and sea surface temperature were studied in an attempt to determine reasons for marine fog development. An evaluation of the credibility and reliability of transient ship synoptic reports also was made.
