The Relationships between the Large Scale Flow Patterns during the Northern Hemisphere Winter and the Rainfall in China Summer
冬季大尺度流型与夏季中国降水量

The rotated singular value decompostion (RSVD) between the 500 hPa height field anomalies over the Northern Hemisphere the preceding winter and the rainfall in China summer are performed based on both data sets of 45 years in the period of 1951 to 1995. The regional characteristic and the time evolution of the dominant coupled correlation patterns are investigated. The researches show that the regional characteristic of the coupled correlation patterns between the large scale flow patterns during the Northern Hemisphere winter and the rainfall in China summer are identified effectively and have a significant physical sense.
