摘　　要：本文见过对２０００～２００１年冬季（１２～２月）大气环流特征的分析，尤其关于东亚大气活动中心的位置、强度的不同会造成渤海海域气候与冰情的差异，表明由于乌拉尔山和北太平洋两大高压脊的变化，造成亚洲极涡与东亚大槽的加强和减弱，并对渤海气温变化和海冰生消的影响起着直接作用。此外．分析还表明，前期拉尼娜现象可能是造成气候变化的重要原因之一。On basis of analysis of the atmospheric circulation in winters 2000/2001, especially of the differences in local climate and sea ice caused by the variation of location and intensity of the atmospheric activity in the east asia, this paper shows that the changes of the ural and north Pacific blocking high lead to the strengthening and weakening of the asia polar vortex and the deep trough in the east asia directly affecting the temperature of the Bohai sea and freezing or melting of the sea ice. Our analysis also shows that the pre- La Nina plays an important role in climate change and sea ice.
