秋季北极海冰对我国冬季气温的影响

影响机制一




影响机制二



注释:西伯利亚高压型(SH)是冬季东亚地区海平面气压场变化的第一个模态(解释方差:50%)。
计算方法:去掉线性趋势后的1979-2013年的东亚地区(30-70°N,80-120°E)冬季DJF平均海平面气压场的EOF第一个模态。(Wu et al., 2015)



影响机制三



注释:亚洲-北极环流型(AA)是冬季东亚地区海平面气压场变化的第二个模态(解释方差:26%)。
计算方法:去掉线性趋势后的1979-2013年的东亚地区(30-70°N,80-120°E)冬季DJF平均海平面气压场的EOF第二个模态。(Wu et al., 2015)
