摘　　要：绕极流海域存在全球最大的波浪输运量,遇陆地阻隔,在大洋东岸形成连接高纬度与低纬度之间涌浪的经向输运通道。本文分析了存在于南极绕极波(ACW)中的波浪信号以及来自绕极流海域涌浪的东向强化特征,并进一步从理论分析及定性计算的角度研究了波浪诱导的经向输运对东赤道太平洋海表面温度变化的影响,提出了波浪过程对厄尔尼诺影响的全新观点。未来工作中,我们将在海浪-海流-大气耦合模式中考虑波浪的大尺度效应,深入探究波浪在大气海洋动力过程中的重要作用。There is the global largest wave transport in the area of the Antarctic Circumpolar Current（ ACC）,which establishes a transport channel between the high and low latitudes on the east coast of the ocean as it encounters land barrier. The wave signals present in the Antarctic Circumpolar Wave（ ACW）and the eastward enhancement characteristics of the swell from the ACC are analyzed in this paper. The influence of meridional transport induced by wave on the surface temperature in the eastern equatorial Pacific Ocean is studied with theoretical analysis and qualitative calculation. A new view of the influence of wave process on El Nio is proposed. In the future research,the large scale effects of the waves will be considered in the air-sea coupling model,and the important role of waves in the process of atmospheric and ocean dynamics will be further explored.
