This paper presents a concise summary of the studies on interdecadal variability East Asian winter monsoon (EAWM) from three main perspectives. (1) The EAWM has been significantly affected by global climate change. Winter temperature in China experienced stages variations beginning 1950s: cold period (from 1950s to early or mid 1980s), warm 1980s 2000s), and hiatus recent 10 years (starting 1998). strength also varied stages: stronger (1950 1986/87), weaker (1986/87 2004/05), strengthening 2005). (2) Corresponding EAWM, atmospheric circulation, China, occurrence waves over have all exhibited coherent variability. upper-level zonal circulation was stronger, mid-tropospheric trough Asia deeper with downdrafts behind trough, Siberian high during than period. (3) seem closely related major modes Pacific sea surface temperature. When Northern Hemisphere annular mode/Arctic Oscillation decadal oscillation were negative (positive) phase, (weaker), leading colder (warmer) temperatures China. In addition, phase Atlantic multi coincided relatively (warm) (weaker) EAWMs. It is thus inferred that ocean may be one most important natural factors influencing long-term EAWM. although warming played significant role weakening
