Abstract: In this paper, the relacionship between interannual variation of Hunan summer monsoon rainfall and El Nino as well as winter Eurasion snow cover is examined. The following conclusions have been obtained:1) when an El Nino event occurred , monsoon rainfall over Hunan during the next year of the El Nino events was usually positive anomalies, which is significant at 1 % level.2 )the correlation coefficient computed between the summer monsoon rainfall over Hunan and the winter Eurasion snow cover is equal to-0.53, which is significant at the 5% level. It agrees with the Huhn-Shukla results. It is suggests that the the Eurasion snow cover may exhibit a similar interaction with the monsoon rainfalls of both India and central China-Hunan.
