Abstract
Based on the analysis of x2 test of global land rainfall time series, it is found that the mean global land annual rainfall reduce significantly when El Niño events occur, and increase evidently in La Niña years. The impacts of ENSO on the winter and autumn precipitation over eastern China are also notable. Usually, the rainfall of winter and autumn over southern China increases, and that over northern China decreases in El Niño years. The effects of ENSO on summer rainfall are not so significant as on autumn and winter rainfall in China. The summer precipitation of area to the north of the Yellow River often decreases in El Niño years. No evident relationship is found between ENSO and spring rainfall in China.
