基于CMIP5 32个模式的多模式集合的历史和RCP8.5运行，研究了全球变暖背景下赤道太平洋海温变化格局的形成机制。研究了纬向El - no-like模式和经向赤道峰值增温（EPW）这两个具有复杂形成过程的特征。气候蒸发是El Ni ~ no-like模式的主要贡献者，而海洋动力恒温器效应起相当的负作用。云短波辐射海温反馈和减弱的Walker环流对El Ni ~ no-like型有小的积极作用。与海洋动力学有关的过程仅限于赤道。正如以往研究表明的那样，气候蒸发也是EPW型的主要贡献者。然而，一些过程的影响与先前的研究不一致。例如，Walker环流减弱引起的纬向热平流变化对EPW型有显著的正贡献，短波辐射变化对EPW型有显著的负作用。
Based on the historical and RCP8.5 runs of the multi-model ensemble of 32 models participating in CMIP5, the present study evaluates the formation mechanisms for the patterns of changes in equatorial Pacific SST under global warming. Two features with complex formation processes, the zonal El Ni˜no-like pattern and the meridional equatorial peak warming (EPW), are investigated. The climatological evaporation is the main contributor to the El Ni˜no-like pattern, while the ocean dynamical thermostat effect plays a comparable negative role. The cloud–shortwave-radiation–SST feedback and the weakened Walker circulation play a small positive role in the El Ni˜no-like pattern. The processes associated with ocean dynamics are confined to the equator. The climatological evaporation is also the dominant contributor to the EPW pattern, as suggested in previous studies. However, the effects of some processes are inconsistent with previous studies. For example, changes in the zonal heat advection due to the weakened Walker circulation have a remarkable positive contribution to the EPW pattern, and changes in the shortwave radiation play a negative role in the EPW pattern.
