| Research Abstract |
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.
