We evaluated the influence of wind-induced waves on El Niño-Southern Oscillation (ENSO) simulations based on the First Institute of Oceanography-Earth System Model version 2 (FIO-ESM 2.0), a global coupled general circulation model (GCM) with a wave component. Two sets of experiments, the GCM, with and without a wave model, respectively, were conducted in parallel. The simulated sea surface temperature (SST) was cooled by introducing the wave model via the enhancement of the vertical mixing in the ocean upper layer. The strength of ENSO was intensified and better simulated with the inclusion of wave-induced mixing, particularly the La Niña amplitude. Furthermore, the simulated amplitude and spatial pattern of El Niño events were slightly altered with the wave model. Heat budget analyses revealed the intensification of La Niña events to be generally attributed to wave-induced vertical advection, followed by the zonal and meridional advection terms.

风浪对ENSO模拟的影响

我们根据第一海洋学-地球系统模型版本2（FIO-ESM 2.0）（全球耦合的一般环流模型（GCM））评估了风浪对ElNiño-南方涛动（ENSO）模拟的影响。波分量。并行进行了两组实验，分别是有波浪模型和没有波浪模型的GCM。通过引入波浪模型，通过增强海洋上层的垂直混合，来冷却模拟的海面温度（SST）。通过包含波感应混合，尤其是拉尼娜振幅，ENSO的强度得到了增强，并得到了更好的模拟。此外，波动模型对厄尔尼诺事件的模拟振幅和空间格局有轻微的改变。
