摘要:
El Niño-Southern Oscillation（ENSO）是热带太平洋海气作用最强的年际信号，其变化会引起全球气候异常，对东亚季风具有重要影响。2000年后中部型El Niño频繁发生，掀起了ENSO多样性研究热潮；El Niño的复杂性也对ENSO理论研究和预测提出了新的挑战。为进一步理解并深入研究ENSO物理机制，本文总结了近年来对两类ENSO的最新认识；特别对副热带太平洋通过海气界面“大气桥”和太平洋副热带-热带经向环流圈的内部经向翻转环流这一“海洋通道”与热带太平洋建立联系的相关成果进行了阐述，并对存在的关键问题进行了展望。

Abstract:
The El Niño/Southern Oscillation (ENSO) is the strongest air-sea coupled interannual signal in the tropical Pacific. Its variation can induce severe global climate change and has a significant impact on the eastern Asian monsoon. Compared to the eastern Pacific El Niño, the occurrence frequency of the central Pacific El Niño has in-creased since 2000. The complexity of ENSO brings new challenges for its theoretical studies as well as its prediction. This paper reviews the related studies on two types of ENSO. We particularly pay attention to the influence of the subtropical variability on ENSO, through both the “atmospheric bridge” and “ocean tunnel.” The North Pacific meridional mode (NPMM) and South Pacific meridional mode (SPMM) are two important components linking the subtropical and tropical Pacific via air-sea interaction; the interior branch of the subtropical-tropical cells (STC) is the important “ocean tunnel.” The scientific issues are proposed, providing a reference for further study.
