The main results are as follows: 1) The east China winter temperature change uniformity is high; 2) Warm winter and cold winter sea level field of pressure synthesis analysis difference mainly in three regions: High latitude Eurasia negative (positive) anoma- lous, Qinghai-Tibet Plain (negative) anomalous and middle latitude Pacific Ocean (negative) anomalous, the corre- sponding winter temperature is exceptionally high (lowly); 3) Correlation analysis is consistent with the synthesis analysis result, formerly a year in December ~ same year February high correlation area mainly distributed in the east- ern hemisphere three regions: The Siberia inverse correlation area, the Qinghai-Tibet Plain and the mi
