两次非典型厄尔尼诺事件发生期间，Ｗａｌｋｅｒ环流中的西太平洋部分显著减弱，Ｈａｄｌｅｙ环流中的东太平洋部分显著增强．西太平洋距平西风应力增强向东伸展；东太平洋距平北风应力增强向南伸展．西太平洋暖池的能量可以两种方式向东传播：赤道Ｋｅｌｖｉｎ波温跃层模态和流速模态．温跃层模态向东输送的总能量大于流速模态向东输送的总能量．１９８２～１９８３年厄尔尼诺事件中，赤道Ｋｅｌｖｉｎ波温跃层模态起主要作用，赤道潜流减弱；１９８６～１９８７年厄尔尼诺事件中，赤道Ｋｅｌｖｉｎ波流速模态起主要作用，赤道潜流增强。厄尔尼诺事件期间，赤道潜流消失、反向现象是一种局地性海洋响应，这种现象不伴随赤道Ｋｅｌｖｉｎ波向东传播．
During the two atypical El Niño events, the western Pacific portion of the Walker circulation significantly weakened and the eastern Pacific portion of the Hadley circulation significantly increased. The western Pacific anomalies westerly winds stress eastward; east Pacific anomalies northerly winds stress southward. The energy of the western Pacific warm pool can propagate eastwards in two ways: the thermocline and velocity modes of the equatorial Kelvin waves. The total energy delivered eastward from the thermocline mode is greater than the total energy delivered eastward from the flow mode. During the El Niño event from 1982 to 1983, the equatorial Kelvin wave thermocline mode played a major role and the equatorial underflow was weakened. During the El Niño event from 1986 to 1987, the equatorial Kelvin wave velocity mode played a major role, and the equatorial underflow increased. During the El Nino event, the equatorial subsurface flow vanished and the reverse phenomenon was a localized ocean response that did not propagate eastward along the equatorial Kelvin waves.
