The objective of this study is to develop classification
equations to forecast the daily probability of occurrence of
marine fog at selected locations on the west coast of the
United States, using parameters easily obtainable from upper-air
soundings and surface observations. In order to achieve
this objective a computerized stepwise linear discriminant
analysis program is extensively employed. Data input consists
of surface and radiosonde observations for the five-year
period 1 July 1968 to 30 June 1973 at three U. S. west
coast stations, namely San Diego and Oakland, California and
Quillayute, Washington.
Tables showing the number of fog and no-fog cases, the
classification functions, and the percentages of correct fog
and no-fog discrimination are presented for each station.
The most capable fog/no-fog discrimination parameters are
discussed for each set of classification equations. Test
results for the San Diego equations using a three-year independent
data set are also shown.
