利用1961-2015年中国冬季气温资料、中国气象局逐月北极海冰密集度指数资料和美国国家海洋和大气管理局(NCEP/NCAR)环流资料, 采用滑动相关、时滞相关及偏相关等分析方法, 探讨了秋季北极海冰对中国冬季气温的影响.结果表明, 秋季北极海冰改变了后期冬季西西伯利亚高压和华北高压强弱, 导致我国西北地区和长江与黄河之间地区冬季气温异常.进一步分析发现, 西北地区冬季气温的异常主要是受西西伯利亚高压影响, 而长江与黄河之间冬季气温的异常主要是受华北高压影响.而秋季北极海冰通过改变后期冬季欧亚中高纬度环流, 进一步影响高原地区冬季气温.%This study used Chinese winter temperature data, the monthly Arctic sea ice concentration index from the China Meteorological Bureau, and NCEP/NCAR circulation reanalysis data to investigate the effects of Arctic sea ice on winter temperatures in China using sliding, time-delay, and partial correlation analyses. The results showed that Arctic sea ice concentration in autumn was correlated with high pressure in West Siberia in late winter and high pressure in North China, which were responsible for winter temperature anomalies in northwestern China and between the Yangtze River and the Yellow River. Further analysis found that the winter temperature anomalies in the northwestern region were affected mainly by high pres-sure over West Siberia, while the winter temperature anomalies between the Yangtze River and the Yellow River were affected mainly by high pressure in North China. The influence of Arctic sea ice on the late-winter high-latitude Eurasian circulation further affected winter temperatures on the plateau.
