Abstract
This study attempts to bridge a gap in our knowledge and understanding of the East Asian monsoon by presenting a documentation of the rainfall and intraseasonal rainfall climatology of summer monsoon rainfall over East Asia. The rainfall climatology is viewed both in terms of its regional characteristics and in relation to the large-scale circulation with the aim of bringing to light the myriad phenomena associated with the East Asian monsoon and its relevance to current mainstream research in monsoon and climate dynamics. Specially, climatology of 30-day and 10-day rainfall records from East Asian stations are studied and compared with satellite outgoing longwave radiation and the large-scale circulation field. Results show that climatologically two major monsoon rainfall onsets over East Asia are identified during the period from April to September. The first, known as the Mei-yu (or plum rain), occurs over central China around the beginning or the middle of June, and the second over northeast ...
