太平洋年代际振荡的研究进展

Advances in Studies of Pacific Decadal Oscillation

作者以太平洋年代际振荡 (PDO)现象为重点 ,系统地回顾了太平洋年代际变率观测、模拟和理论研究的国内外进展。在PDO时空结构方面 ,总结了PDO的基本观测事实 ,在PDO成因方面 ,从海洋大气相互作用观点出发比较了三类PDO形成机制的理论或假说 ,讨论了现有理论或假说中存在的若干问题 ,并提出了未来研究的方向和需要解决的关键科学问题。作者也简要介绍了东亚及中国气候年代际变化的特征及其和太平洋海表温度异常的联系 ,并讨论了东亚大气环流异常在PDO形成中的可能作用。

This review summarizes major advances in the observational and theoretical studies of the Pacific Decadal Oscillation (PDO) phenomenon. The spatio-temporal structures of the PDO are described and three categories of existing theories or hypotheses associated with the large-scale air-sea interaction are compared and discussed. The problems and unresolved issues in these theories are proposed, and future prospects are suggested. Moreover, the interdecadal climate variabilities in East Asia and China are also reviewed and possible role of these variations in the PDO is also discussed.
