In this study,the monthly and seasonal telecorrelation intensity indices of the Pacific/North American (PNA), Western Atlantic (WA), Western Pacific (WP), Eastern Atlantic(EA)and Eurasian(EU) patterns for the period from1951 through 1990 are calculated. On this basis,their climatic variations and the relation between the five telecorrelation intensity indices and the El Nino events are examined. It is noted that when El Nino is at its mature stage(winter),the weak WP pattern is mainly characteristic of the circulation and the strong PNA pattern is the next. The mature stage of El Nino occurring in 1991 is found to be characterized by the weak PNA and WP patterns. Besides,the application of the telecorrelation intensity indices to weather prediction is discussed.
