During the ENSO event period,the Indian Ocean SST will be almost anomalous simultaneously.Some research results indicate that the Indian ocean SSTA would mainly influence the climates of Bengal,IndoChina,Indonesia,India and China.The Indian ocean SSTA is important to Asian climate especially to the anomalous precipitation pattern of China.Based on the IAPGCM2L model developed in the Institute of Atmospheric Physics,Chinese Academy of Sciences and the SST data of Indian ocean and median Pacific ocean during January to June,1999 and 2000 in the model, the monthly precipitation prediction of eastAsia region were obtained in this paper. The results indicate that the SSTA of the Indian ocean and the median Pacific ocean would mainly influence the atmospheric circulation and the precipitation of eastAsia region. The monthly precipitation prediction of the numerical simulation is effective in the most regions of eastAsia, especially in southwest China and south China.
