| 摘 要： | 本文分析了南亚高压的气候特征及南亚高压月际间振荡与华南汛期天气的关系,结果表明,初夏振荡中心偏北同时偏东,不利华南雨季多雨水;盛夏振荡中心偏北同时偏东,有利华南沿海多台风,并建立了相应的预报判据。

| Abstract: | This paper summarizes that with the help of longitudinal (latitudinal) intensity indices, it is able to point out the monthly limited district for South Asian High objectively, and is advantageous to make a quantitative analysis of South Asian High. There exists monthly variations in the eastwest northsouth directional oscillations for South Asian High. In early summer, the center of oscillation directs simultaneously northward and eastward,and this is disadvantageous for precipitation; otherwise, it is in favour of precipitation. In mid-summer, the center of oscillation directs simultaneously northward and eastward, and this is advantageous for the appearance of the prevailing typhoon along the coastal areas of South China; otherwise, the typhoon is infrequent. If the center of oscillation for South Asian High directs southward in October plenty of precipitation would appear in the early summer (May-June) of the next year; otherwise, the rainfall would be much less. Of the center of oscillation directs simultaneously northward and eastward in March, there would appear prevailing typhoon along the coastal areas of South China in the mid summer of the very year ; otherwise, the appeance of typhoon would be much less. |
