In this modeling study, NASA GISS ModelE atmospheric general circulation model was employed to investigate the atmospheric response to winter (DEC-FEB) sea ice anomalies. Two sensitive cases were simulated, one used 10-yr linear trend of winter sea ice concentration in the high latitude of north hemisphere from 40°N to 90°N (Atrend) as the imposed boundary forcing and the other used 10- yr linear trend of winter sea ice concentration in north Pacific sector (Ptrend, 60-80°N,30°W-45°E). The responses were obtained from the mean difference between the sensitive experiments and the control. The effects of sea ice anomalies on China winter temperature were discussed, especially, the way of China winter response to the sea ice anomalies were further revealed.
