Scientists look to mid-Pliocene to inform future behavior of East Asian summer monsoon

The East Asian summer monsoon (EASM) stands as the most northerly extending monsoon system, defined by its remarkable seasonal march. It features a stepwise northward migration of rainfall stages, starting with the pre-Meiyu season in southern China in mid-May, progressing into the Meiyu season (known as Baiu in Japan and Changma in Korea) from mid-June to mid-July, and ultimately extending to northern China by mid-July.
