| 摘 要： | 采有英国Hadley中心的GISST海冰面积资料，NCFP／NCAR再分析资料以及中国160站气温和降水资料，分析了春季格陵兰海冰面积与夏季中国区域气温和降水的关系。初步研究表明，春季格陵兰海冰面积变化和随后夏季我国黄河长江中下游之间地区气温以及8月份华北和西南地区降水呈明显正相关，而和6月黄河中上游地区降水则具有明显的负相关。同时，春季格陵兰海冰异常时期对应着北半球大气环流的明显主为化，表明海冰与我国气温及降水之间的联系具有一定的环流背景。

| Abstract: | Based on GISST sea ice extent data set of Hadley center,UK and NCEP/NCAR reanalysis data as well as surface air temperature and rainfall data from 160 stations in China, the relationship among spring sea ice extent change in Greenland and regional surface air temperature as well as rainfall during summer in China is investigated.Results indicate that spring Greenland sea ice extent is positively correlated with surface air temperature in between the mid low reaches of Huanghe River and the Yangtze River during summer as well as rainfall in North China and Southwest China in August,whereas is negatively correlated with precipitation around mid up valleys of Huanghe River in June.In addition, remarkable changes of NH general circulation associated with spring Greenland sea ice anomalies make clear that the relationship between sea ice and surface air temperature as well as rainfall in China has corresponding background of general circulation change. |
