Graphical Abstract

 

Plain Language Summary: In the first half of winter 2020/21, air temperature anomaly over East Asia was lower than normal, however, it turned into higher condition in the second half of the winter. This study showed that the anomalous coldness in the first half of the winter was due to enhanced convection around the South China Sea, while the warmth was associated with eastward-shifted anomalous convection over the Philippine Sea. We also demonstrated that the teleconnection pattern caused by the anomalous heating around the South China Sea is regionally phase-locked because of the background convergence of the upper-tropospheric winds.
