The climatic distribution features of the monthly precipitation and the annual variation of the seasonal precipitation from 1951 to 2000 in the Northern Xinjiang are analyzed. And the obvious response of the precipitation of the rainy season (AMJJ) and the monthly precipitation in the Northern Xinjiang (average for 5 stations) to SST over the equatorial eastern Pacific and to southern oscillation index (SOI) are revealed emphatically.Furthermore,by using SST and SOI in the previous period as the predictors,the predictive equation of precipitation during the rainy season in the Northern Xinjiang is set up.The equation has the great application value for the long-range forecast of the rainy season precipitation in the region.
