摘　　要：采用“递归分解”方法的逆向算法，提取了赤道东太平洋冷水区５７ 个格点 １９５１年 １ 月～１９９７ 年 １２ 月逐月海温月际变差值序列动力演化的“容比”特征，据此揭示了海温场的年代际尺度气候变化，并讨论了它与 Ｅ Ｎ Ｓ Ｏ 循环、两半球臭氧以及北半球对流层、平流层大气温度年代际变化的关系。最后将“递归分解”方法与传统统计方法进行了比较。By using the negative directions algorithm of “recursive resolve”,the content characteristics of dynamical evolution are revealed for inter monthly differences of Equatorial Eastern Pacific monthly mean SST in 1951.1~1997.12,showing the inter decadal variations and abrupt changes of SST.Relations of the content characteristic with ENSO cycles,the total ozone over the both Hemispheres and inter decadal variations of northern Hemisphere tropospheric and stratospheric temperatuers are also discussed.At last,comparison shows that the content of “recursive resolve” is more sensitive to the inter decadal variations of SST in the region than traditional statistical series.
