| Abstract: | Based on the basic principles and analysis methods of the statistics and climatoragy this paper shows preliminaryly the characters and circulation backgrounds of the gale at the west coast of the Taiwan Strait. The results are. (1) The prevail seasons of the gale mainly appeare in October to March and the wind dircction is usnally NNE to ENE. (2) The gale days most frequently appeate in the northern part frequently in the southern part, and less in the middle section in prevail seasons. But the gale days in southern, middle, northern sections and the whole area have evident similalily, showing periodic variations 5a and 7a basis. (3) The development of the 500hPa circulation in the middle latitude and the strong or weak subtropical heights in the low latitude are the main circulation backgrounds that determine the gale days in prevail seasons. For example, when the zonal circulation appeares in the middle-latitude and a weak subtropical height appeares in the low-latitude and a weak subtropical height appeares in the low-latitude, the gale days would be less, and vice versa. |
