• Through climatological analysis on the fog occurrences over and near the East Sea, we show that the fog occurrences are closely associated with the strength of Asian summer monsoon and topographic characteristics, and that climatological change is progressing over the East Sea. Also we examine the predictability of sea fog. In case of the strong summer monsoon with the strong south-westerly wind and the strong contrast between high pressure system over the Pacific Ocean and low pressure system over the Asian land, fog occurrence frequency increases. The fog-concentrated season coincides quantitatively with the progress of summer monsoon. At the southern area, fog occurrence becomes frequent from 19 pentads till 42 pentads of the year and at the northern area from 30 pentads to 45 pentads. At Kangnung station, sea fog occurs from June till August and steam fog occurs from September till June, and thus total fog is the most frequent in June. In addition, warmer temperature and larger annual variation of temperature cause more fog frequencies, and larger annual variation of mean temperature causes the larger variation of fog frequencies. Associated with topographic characteristics, fog occurrence is much more frequent at the western side of the East Sea than elsewhere. Also, it is the most frequent at the stations opened directly to the north-easterly cold sea-current. Other important characteristics which are considered climatological changes over the East Sea are detected by the several kinds of computation. Those are the rapid decrease of fog occurrences and gradual northward movement of fog-occurrence area per year. Predictability of the sea fog is detected also. The 60% of whole sea fog cases are classified as one category by the statistical model. Other cases could be categorized also if observed data are sufficient. It is proposed that completion of the categorized data will make progress on the model itself and predictability. (rdf:langString) (en)
