The concept of the “Asian monsoon” masks the existence of two separate summer rainfall regimes: convective storms over India, Bangladesh and Nepal (the South Asian monsoon) and frontal rainfall over China, Japan and Korea (East Asian monsoon). In addition, the Tibetan Plateau and other mountains impacts the atmospheric circulation and hence precipitation patterns. Here we focus on the East Asian summer monsoon, and present analysis of precipitation variability over the past 50 years and the Last Glacial Maximum. The discussion will highlight the roles of moisture sources and mechanisms for precipitation changes.
