Weak linkage of winter surface air temperature over Northeast Asia with East Asian winter monsoon during 1993–2003

A colder winter over Northeast Asia (NEA) has traditionally been attributed to the stronger East Asian winter monsoon (EAWM) on interannual timescale. However, the present work proposes this robust linkage becomes weak during 1993–2003, along with the changes of the underlying condition in the last three decades. During 1981–1992 and 2004–2016, the loss of autumn Arctic sea ice condensation (SIC) leads to the stratospheric warming and the polar...
