  • By analyzing the linkage of the Northern Annular Mode (NAM) anomaly to the East Asian jet and the East Asian trough during Stratospheric Sudden Warming (SSW), the influence of SSW on East Asian weather is studied. The results show that the East Asian jet is strengthened and the East Asian trough is deepened during SSW. With the downward propagation of SSW, the strengthened East Asian jet and the East Asian trough would move southward, expand westward and gradually influence the area of north and northeastern China. This implies that the winter monsoon tends to be enhanced over East Asia during SSW.
