  • By using Singular Value Decomposition (SVD) technique and monthly mean 500 hPa height data in the Northern Hemisphere from 1951 to 2000, the inter-seasonal relationships of general circulation anomalies are studied. The results show that the first mode derived from SVD indicates the key coupled characteristics-there exists close temporal and spatial correlation between seasonal 500 hPa height anomalies and its former seasonal 500 hPa height anomalies. Especially there are obvious connections between the general circulation anomalies in summer and those in past winter and spring. The variations of the East Asian trough, North American trough, polar low, North Pacific oscillation and Siberian high of the North Hemisphere 500 hPa in winter and spring play important roles in the general circulation anomalies in the following summer and autumn in East Asian.
