| Abstract: | By using the data of monthly precipitation (April-June) of 19 stations in Guangdong and 500hPa geopotential height during 1957～1999,the major difference between 500hPa composite field that associated with drought and flood anomalies in the first rainy season and those of previous period is analysed and discussed.The characteristics of the 500hPa geopotential height in the peoiod prior to the first rainy season in the key month and key area are also analysed.The results may be used as criteria for forecast of anomalous drought and flood in the first rainy season in Guangdong. |
