| 摘 要： | [Objective] Study on the spatial distribution of summer precipitation patterns and interannual and interdecadal variability.[Method] The summer precipitation patterns were obtained from standard field of summer precipitation data for 160 observation stations in China during 1951-2000 by the utilization of empirical orthogonal function(EOF),and characteristics of interannual and interdecadal variability were analyzed.[Result] The summer precipitation mainly distributes in eastern part of China;The 1st,2nd and 3rd EOF modes of spatial distribution are especially remarkable as well consistent with the results of previous reports about three rainfall patterns from analysis on the percentages of precipitation anomaly of summer.[Conclusion] There exists interannual and interdecadal variability for summer precipitation in China.
