[1]我们提供的证据表明，热带太平洋热收支中的非线性动态加热（NDH）在强烈厄尔尼诺事件的产生以及观测到的厄尔尼诺（暖）和拉尼娜（冷）事件之间的不对称性中是必不可少的。与厄尔尼诺活动增强相关的NDH增加对近期热带太平洋变暖趋势产生了影响，可能为热带太平洋气候变化提供了正反馈机制。
[1] We present evidence showing that the nonlinear dynamic heating (NDH) in the tropical Pacific ocean heat budget is essential in the generation of intense El Nino events as well as the observed asymmetry between El Nino (warm) and La Nina (cold) events. The increase in NDH associated with the enhanced El Nino activity had an influence on the recent tropical Pacific warming trend and it might provide a positive feedback mechanism for climate change in the tropical Pacific.
