摘要

By using the synoptic chart, densified observation of precipitation and sounding data, the characteristic of the short-duration heavy rain which occurred over China mainland under the region which controlled by 500 hPa Subtropical High of west Pacific in autumn 2010 are analyzed. Moreover, the typical examples are analyzed by mesoscale weather chart anaysis. Then the respect of mesoscale weather chart analysis would be given. Results demonstrate that the short-duration heavy rain is familiar in the region which controlled by 500 hPa Subtropical High of west Pacific in autumn 2010, especially in September. The occurrence days of short-duration heavy rain in the region which controlled by 500 hPa Subtropical High of west Pacific in autumn 2010 are decreased from September to Aoctober. The occurrence days of short-duration heavy rain in September are the most which are 76.7% of the Subtropical high control days. In autumn the occurrence days of Short-duration heavy rain which controlled by Subtropical High are 47.5% of the Subtropical high control days. The short-duration heavy rain under the region which controlled by subtropical high occur in the forenoon more than in the afternoon except in November. In November there is no short-duration heavy rain under the region which controlled by 500 hPa subtropical high of west Pacific. When we analyze the short-duration heavy rain under the 500 hPa subtropical high of west Pacific in autumn 2010 by using the mesoscale weather chart analysis, we should pay attention to the significant moist region in the low level, the baroclinicity of Subtropical High, convergence of air flow in the low level, orographic uplift, 925 hPa level, thermal condition of surface and convergence of water vapour etc..
