| 摘 要： | 对近４５年（１９５１～１９９５年）前期冬季北半球５００ｈＰａ高度距平场和夏季中国降水量进行旋转奇异值分解（ＲＳＶＤ），研究了耦合相关空间分布的区域特性，同时分析了相关型的时间演变。结果表明，旋转奇异值分解有效地揭示了前期冬季北半球５００ｈＰａ大尺度流型与夏季中国降水耦合相关型的区域分布特征，并且物理意义明确。

| Abstract: | 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. |
