摘　　要：利用北极海冰面积资料和NCEP/NCAR再分析逐月高度场、风场资料以及中国160站气温资料,探讨秋季区域海冰异常与冬季大气环流及区域气候的关系,结果表明,秋季东西伯利亚海海冰的年际变化与北半球冬季大气环流及东亚冬季风有着密切的关系,秋季该海区海冰偏多(偏少),相应冬季东亚冬季风偏强(偏弱);进一步分析发现秋季该海区海冰面积偏大(偏小),相应冬季中国大部地区气温明显偏低(偏高)。The relationship between autumn sea-ice anomaly and winter atmospheric circulation as well as east Asia regional climate is investigated by means of correlation and composite analysis. It bears evident connection between the autumn sea-ice anomaly and winter atmospheric circulation as well as winter monsoon with heavy (light) sea-ice corresponding to strong(weak) East Asia monsoon. Further study shows that autumn heavy(light) sea-ice extent is followed by low (high) winter temperature in most of China.
