A METHOD FOR FINDING SEA-BREEZE DAYS UNDER STABLE SYNOPTIC CONDITIONSAND ITS APPLICATION TO THE SWEDISH WEST-COAST

A method for selecting sea breeze days in an archipelago was developed with special application to the West Coast of Sweden. The primary cri terion for identifying a sea breeze was the occurrence of a distinct c hange in surface wind direction within a 24 h period. The data used in the study were gathered using hourly meteorological records from fiel d stations situated on the West Coast. Six different filters were incl uded in the method; each of them developed from empirical knowledge of the physical processes responsible for the occurrence of a sea breeze system. Using this method it is possible to create a data set of sea breeze days, which does not use distance to the shoreline as a necessa ry condition for classification.
