The progresses of recent studies on the variabilities of the East Asian monsoon and their causes

The variabilities of the East Asian summer monsoon are an important research issue in China, Japan, and Korea. In this paper, progresses of recent studies on the intraseasonal, interannual, and interdecadal variations of the East Asian monsoon, especially the East Asian summer monsoon, and their causes are reviewed. Particularly, studies on the effects of the ENSO cycle, the western Pacific warm pool, the Tibetan Plateau and land surface processes on the variations of the East Asian summer monsoon are systematically reviewed.
