摘　　要：The SST anomaly of the central-eastern equatorial Pacific and the arctic sea ice anomalies of the four districts lo- cated respectively in 160°E—110°W,110°W—20°W,70°E—160°E and 20°W—70°E are taken as five separate factors. And the relationship between each factor and the atmospheric general circulation and the climate is investigated by observational analysis and numerical experiments.It is shown that the effects of the arctic sea ice anomalies on the varia- tions of atmospheric circulation and climate are comparable to or even in some cases greater than that of EI Nino events.So one should pay much attention to the study of polar sea ice anomalies in climate research.The SST anomaly of the central-eastern equatorial Pacific and the arctic sea ice anomalies of the four districts lo- cated respectively in 160°E—110°W,110°W—20°W,70°E—160°E and 20°W—70°E are taken as five separate factors.
