Dynamics and predictability of the winter climate over the Far East

研究了东亚冬季风的年际变化。该项目已经阐明，冬季季风可以受到上层中纬度西风带的变化、北极振荡以及热带和黑潮延伸区海面温度变化的强烈影响。为了更准确地描述三维拉格朗日运动，我们还在变换的欧拉平均方程中提出了剩余环流的“新”定义。该项目有助于进一步了解冬季季风的动态和改善可预报性。

Interannual variability of the East Asian winter monsoon is investigated. This project has clarified that the winter monsoon can be strongly influenced by the variability of the midlatitude westerlies at the upper levels, the arctic oscillation, and sea surface temperature variability over the tropics and Kuroshio extension region. We have also proposed a"new"definition of the residual circulation in the Transformed Eulerian Mean equations to depict three-dimensional Lagrangian motion more precisely. This project contributes further understanding of the dynamics and improvements of predictability of the winter monsoon.
