| 摘 要： | 通过构建海陆间大气质量迁移(MAMLO,Migration of Atmospheric Mass over regions between Lands and Oceans)指数,对北半球夏季亚洲—北太平洋上空大气质量的迁移规律及其与气候异常的联系进行了研究。结果表明:在北半球中高纬亚洲大陆和中低纬北太平洋上空异常大气质量呈现反相变化。夏季MAMLO指数总体呈缓慢下降的趋势,同时还具有准3 a振荡周期以及显著的年代际变化特征。亚洲大陆中高纬地表气压变化与北太平洋低纬气压变化的反相关关系主要归因于:异常大气质量环流;海陆异常加热对比;Rossby波能传播。MAMLO与欧亚、太平洋地区夏季气候异常关系密切,尤其在中国地区。MAMLO为正(负)时,中国大体呈现出北方降水偏多(偏少)南方降水偏少(偏多)、北方偏冷(偏暖)南方偏暖(偏冷)的空间分布。
