摘要研究了索马里和澳大利亚越赤道气流（CEFs）年际反向联系（跷跷板）强度的年代际变化。在20世纪60年代中期之前和21世纪初之后，年际跷跷板连接的强度相对于20世纪60年代中期和21世纪初之间的时期明显减弱。这种年际波动强度的年代际变化与ENSO强度的年代际变化有相似之处，并可进一步归因于大西洋年代际振荡（AMO）的相变。当AMO处于正位相时，ENSO振幅减小，跷跷板强度减弱，反之亦然。CMIP5模型的历史模拟输出被用来验证连接，并获得了类似的结果。因此，CEF之间的年际相反联系（跷跷板）的强度受到AMO调节的观点是强有力的。
Abstract The decadal variation of the intensity of the interannual opposite connection (seesaw) between the Somali and Australian cross-equatorial flows (CEFs) is investigated. During the period prior to the mid-1960s, and after the early-2000s, the intensity of the interannual seesaw connection is significantly weaker relative to the period between. Such interdecadal shifts in the interannual seesaw intensity bear a resemblance to the decadal shift in ENSO’s strength, and can be further attributed to the phase transition of the Atlantic Multidecadal Oscillation (AMO). When the AMO is in a positive phase, the ENSO amplitude reduces and the seesaw strength becomes weakened, and vice versa. The historical simulation outputs of the CMIP5 models are used to verify the connection, and a similar result was obtained. Thus, the notion that the intensity of the interannual opposite connection (seesaw) between the CEFs is modulated by the AMO is robust.
