| 摘 要： | 冰冻圈作为下垫面的一个重要组成部分 ,与大气处于不断的相互作用过程中。文中主要研究了北极海冰与中国华北地区降水的关系。研究结果揭示了中国区域与北半球季尺度气候变异前期北极海冰“强信号”现象。探讨了中国华北地区旱涝前期北极海冰特征 ,比较了华北旱涝前期北极海冰相关区域特征分布 ,并揭示出北极海冰“强信号”区与中国区域夏季降水的相关分布 ,分析了北极海冰“强信号”区对华北地区夏季旱涝影响的动力结构特征。

| Abstract: | As an important part of underlying surface,cryosphere is in the process of continuous interaction with atmosphere.The present paper is mainly about the relationship between Arctic sea ice and the precipitation of North China.It is shown that the Arctic sea ice strong signal region is highly correlated with the summer precipitation of North China.The mechanism of how the Arctic sea ice would affect North hemisphere summer circulation and the flood drought of north China is put forward,namely how the Arctic strong signal region may affect the abnormal precipitation of North China is put forward. |

| Keywords: | Arctic sea ice Precipitation of North China Strong signal region |
