Abstract:By using normalized difference vegetation index (NDVI), the daily rainfall data and the NCEP/NCAR reanalyzed data during January 1982—December 2001, the relationship between winter NDVI over T-P and summer precipitation in China is analyzed by SVD, it suggests that the distribution of correlation coefficient shows “+-+-” from south to north. When the winter NDVI is high (low), the summer precipitation in the region of Yangtze River and northeast China is decreased (increased), but the summer precipitation in Huanan and Huabei is increased (decreased). The variation of the summer monsoon of east Asia in winter NDVI high and low years is analyzed by using composite analysis. The result indicates that when the winter NDVI of T-P is high, Mascarene high tends to be weak, but Australia high tends to be strong, and the intensity of equatorial convergence belt (ITCZ) is inclinable to being strong, it makes the cross-equatorial flow strong and the South China Sea monsoon outbreak early. At the same time, the South Asia High is weaker and its position is more westward, but the location of western Pacific subtropical high is close to east and north, and the position of subtropical westerly jet is close to west and north.
