| 摘 要： | 采用Hadley中心的海冰密集度资料和中国160站气温资料,对冬季北极海冰变化的主要模态进行了分析,定义了5个关键海区,重点讨论了冬季北极海冰异常与中国冬季气温的关系。结果表明,冬季北极海冰变化主要表现为第一模态,即太平洋、大西洋的海冰反位相分布。海冰变化的关键区域为区域Ⅰ巴伦支海、区域Ⅱ格陵兰海、区域Ⅲ戴维斯海峡、区域Ⅳ白令海以及区域Ⅴ鄂霍次克海。中国冬季平均气温、冬季最低气温、冬季最高气温均与北极关键海区的海冰异常有显著相关,但是与其对应的海区有所不同。

| Abstract: | Based on the sea ice concentration data of Hadley Center and winter air temperature of 160 stations in China,the EOF modes of winter arctic sea ice variation are studied,and five key sea areas（Barents Sea,Greenland Sea,Davis Strait,Bering Sea and Okhotsk） are defined.This paper focuses on relationship between winter sea ice variation and the synchronous winter air temperature in China.Results show that the first EOF mode exhibits out of phase distribution between Atlantic and Pacific sea ice.There has significant correlation between Arctic sea ice variation of the key sea areas and winter mean air temperature,minimum temperature and maximum temperature in China. |
