  6. Based on the epwp and wpwp in conjunction with abnormal north and west wind, a new possible iii mechanism is provided for the evolution of the 1997 / 1998 el nino. to be specific, the warm kelvin wave propagating to east excited by the abnormal west wind can suppress the cold upwelling flow in the eastern pacific, which, in turn, is favorable to the eastern pacific sst increase ; abnormal west wind can make the warm water of the wpwp east edge extend to east, which is conductive directly to eastern pacific sst increase ; the abnormal west wind propagating to east can make the sea surface warm water near two equatorial laterals converge to the equator by ekman drifting, which, in rum, strengthens the downwelling flow near the equator, leading to eastern pacific sst increase

    將東、西太平洋暖池及異常北風、西風一併結合起來考慮，提出1997 1998elnino事件發生、發展的一種新的可能機制：異常西風激發東傳的暖kelvin波對東太平洋的冷上翻流有抑制作用，從而有利於東太平洋海表溫度增加；異常西風驅動西太平洋暖池東端暖水向東伸展直接有利於東太平洋海表溫度增加；東傳的異常西風可以通過埃克曼漂流效應將赤道兩側的海表暖水向赤道輻合從而加強了赤道附近的下沉流，也有利於東太平洋赤道附近海表溫度增加。
