| Abstract: | Inter-ekad variation of precipitation (IDVP) and its space distribution during rainy season (May to Sep.) in the Jiang-huai valleys are analysed by using correspondence analysis method. Also, the areas can be divided into four rainfall regions according IDVP. Finaly, the typical circulation background for IDVP during rainy seasons are discussed. |
