Abstract: The relationship between the summer precipitation in northern Xinjiang and sea surface temperature was investigated using monthly precipitation data during 1960—2004 of 36 meteorological stations in northern Xinjiang and monthly mean sea surface temperature data during 1960 2004 reconstructed by NCEP/NCAR. The results were as follows. Summer precipitation anomaly in northern Xinjiang didn't relate to ENSO. Summer precipitation anomaly in northern Xinjiang was remarkably sensible to sea surface temperature anomaly in last winter and spring in 5 sea areas which were northern Indian Ocean (20° S—20° N, 60°—110° E), western Pacific warm pool and Kuroshio extent (0°—30° N, 110°—150° E), tropical middle-eastern Pacific (5° S—5° N, 80°—150° W), northern Atlantic (30°—50° N, 20°—60° W)and tropical Atlantic (0°—20° N, 20°—60° W). There is a prominently positive correlation between summer precipitation in northern Xinjiang and spring sea surface temperature anomaly in the 5 sea areas, and it can be used for prediction of summer precipitation in northern Xinjiang.
