中文摘要	从冷暖系统配置的角度,选取东亚夏季风(EASM)和7月亚洲区极涡面积(APVA),分析了二者的气候特征与中国夏季降水分布之间的关系.在此基础上,将1951—2010年EASM和APVA的异常配置分为四种类型:A:季风强、极涡大;B:季风强、极涡小;C:季风弱、极涡大;D:季风弱、极涡小.研究发现,二者的异常配置下,中国夏季大尺度旱涝分布在季尺度上表现出多面性特征:A型年,夏季整体偏旱;B型年,夏季南涝北旱;C型年,夏季北涝南旱;D型年,夏季整体偏涝.由此可见,中国夏季旱涝总体分布除了与EASM有关外还与APVA密切相关,二者异常的不同配置下,夏季降水多寡和旱涝分布表现出了显著的差异和规律性,这...
