The four seasons'significant teleconnection on both interannual and interdecadal scales of sea surface temperature anomaly between North Atlantic and North Pacific are demonstrated using the diagnostic method of SVD(Singular Value Decomposition).The anomaly index I of sea surface temperature anomaly is constructed of the time coefficient of the principal SVD pattern.The correlation of index I with anomalies of contemporaneous Asian-Pacific summer monsoon and the summer precipitation of eastern China are analyzed.The results show that the teleconnection pattern between North Pacific and North Atlantic SST is correlated with the anomaly of summer Asian-Pacific monsoon on both interdecadal and interannual scales,and remarkably with the precipitation of the Yangtze River valley on interannual scale.
