Abstract:

NCEP/NCAR reanalysis data and a 30-year precipitation dataset of observed daily rainfall from 109 gauge stations are utilized in this paper. Using the REOF we analyzed the spatial distribution of precipitation in the 109 stations in the Yangtze River Basin in Meiyu periods from 1978 to 2007. The result showed that the spatial distribution of precipitation in the Yangtze River Basin can be divided into the south and north part. As a result, relationships between an atmospheric heating source (hereafter called ) over the Asian region and the precipitation on the south and north side of Yangtze River in Meiyu periods were separately studied in this paper. The results are shown as follows. The flood/drought to the north of Yangtze River (NYR) was mainly related to the over the East Asia summer monsoon region: when the over the Philippines through Western Pacific and the south China was weakened (strengthened), it would probably result in the flood (drought) in NYR; and the precipitation on the south side of Yangtze River (SYR) was related to the over the east Asia and Indian summer monsoon region: when the over the areas from south China to the northern East China Sea and Yellow Sea and south-eastern Japan was strengthened (weakened), and the over the areas from the Bay of Bengal to south-eastern Tibetan Plateau was weakened (strengthened), it will lead to flood (drought) in SYR.
