The monthly average temperature data in winter (from December to February) of 74 stations distributed in Northeast China from 1959 to 2002 were decomposed by means of EOF. Based on EOF_1 time coefficient and SST data from 1958 to 1999, the relationship between winter temperature anomaly in Northeast China and the globe preceding SST was discussed. The key sea areas in the key periods with significant influences were determined. The prediction of winter temperature anomalies was further studied with key areas' preceding SST. The results showed that there was a more significant and stable relationship between winter temperature and preceding SST. SST in certain period and area could be used as an important influence factor for the forecast of winter temperature anomaly and the mistake of prediction was very seldom.
