Title: CHARACTERISTICS OF THE SOUTH CHINA SEA MONSOON IN DROUGHT/FLOOD OF THE YANGTZE RIVER-HUAIHE RIVER VALLEY DETERMINED WITH THE QUIKSCAT DATA
Abstract: Based on the Quik SCAT data of 2001 and 2003, the variation characteristics of South China Sea summer monsoon and the relationship between its LFO components and the rainfall in Yangtze River~Huaihe River basin are analyzed for its drought/flood years. The results are shown as follows.(1) In 2001 and 2003, the onset of South China Sea monsoon took place at nearly the same time, but the monsoon was interrupt in the middle of June, 2003. In 2001, the monsoon advanced northward and its center rapidly moved from 8N to the northern part of the South China Sea, while in the same period of 2003, the monsoon was wandering about in the central-south of the South China Sea.(2) In the two years, there were three pairs of oscillation centers which propagated northward significantly and displayed almost opposite LFO phase in the low-frequency wind field, but in terms of intensity and duration, the 2001 monsoon is stronger and lasted longer than that of 2003.(3) The IM-SCS and IN-SCS are defined, according to the location of the strong center regions of low-frequency wind, and a pronounced, negative lagging-correlation is found between the indices and the rainfall of June and July in the Yangtze River~Huaihe River basin and in the middle and east parts of Tibetan Plateau. However, the relationship between the low-frequency monsoon index and the rain of the middle and western parts of Yunnan Province and some of the North China region show a pronounced, positive lagging-correlation.
