The frequent occurrences of the second-year surface cooling condition in the eastern equatorial Pacific, as observed in late 2021, are attributed to decadal changes in the thermocline depth, which determine the relative dominances of local cooling effect in the east and subsurface warming effect remotely from the west. Coupled models need to adequately represent these processes in a balanced way, thus being able to successfully predict the observed sea surface temperature evolution in late 2021.
如2021年末观测到的那样，赤道东太平洋频繁出现次年表层降温状况，这归因于温跃层深度的年代际变化，温跃层深度决定了东部局部冷却效应和西部远程次表层变暖效应的相对主导地位。耦合模型需要以平衡的方式充分体现这些过程，从而能够成功预测2021年末观测到的海表温度演变。
