Statistical-empirical forecasting guidance for the occurrence of fog at Mount Gambier Airport

The forecasting problem Mount Gambier Airport, in the southeast of South Australia, is one of the most fog-prone aerodromes in South Australia. At Mount Gambier Airport, the occurrence of fog has greater impact on aviation operations than does any other weather phenomenon. On average, fog occurs at Mount Gambier Airport on about 40 days each year and can occur in any month although the mid-year months are more susceptible. In 1961, there were 96 days when fog was reported. (In that year too, many other locations in southeast Australia, such as Canberra, East Sale, and Launceston, experienced an abnormally high number of fog days.) In May 1991, fog was reported on 14 consecutive days at Mount Gambier. Aust. Met. Mag. 50 (2001) 15-27
