中文摘要：
利用北极海冰面积指数和中国160站降水资料,探讨了冬季戴维斯海峡海冰和华北7月降水年际变化的相关特征,并分析了二者年际关系的年代际变化。结果表明,冬季戴维斯海峡海冰与华北7月降水在年际时间尺度上呈反相关关系,1974年前后两者的年际关系由反相关较强转为变弱。冬季戴维斯海峡海冰与中国7月160站降水的年际相关分布在1974年前后由东部型转变为江淮型。

英文摘要：
The interannual correlation of the winter sea-ice of Davis Strait with July rainfall of North China and its decadal variability are analyzed in this paper by using the Arctic sea-ice area data and the monthly rainfall of 160 stations in China.Analysis results show that there exists a negative interannual correlation between winter sea-ice of Davis Strait and July rainfall at 160 stations in China,with a turning point from a strong negative correlation to a weak negative correlation at 1974.The interannual correlation pattern between winter sea-ice of Davis Strait and July rainfall of North China has changed from the East-pattern to the Jianghuai-pattern around 1974.
