%X The atmospheric responses to positive SSTA with different durations in the eastern equa-torial Pacific are studied by using IAP-2-level AGCM and 9-level spectrum AGCM. The analyses ofsimulated results show that the excited anomalies of atmospheric circulation and climate in East Asia insummer are quite similar evens though positive SSTA in the eastern equatorial Pacific is kept for differ-ent duration (in January;; in January-February and in January-April;; respoctively);; and the excitedanomalies also resemble each other in the temporal evolution. Therefore;; as an external forcing;; theSSTA in the eastern equatorial Pacific will evidently impact the variations of atmospheric circulationand climate in East Asia;; but this influence is not sensitive to the duration of SSTA. In a sense;; it isshown that the occurrence and intensity of SSTA should be given more attentions to when we predictshort-range climate variation with the GCM.
