摘要：

太平洋年代际振荡(PDO)是影响亚洲—太平洋气候,乃至全球气候变化非常重要的海洋模态之一。目前为止,有关PDO形成的动力根源及机制仍不清楚。本文聚焦20世纪PDO的空间模态和时间序列演变,系统分析了CMIP5框架下25个耦合模式开展的109个历史时期模拟试验的结果。结果显示,大多数耦合模式可以成功模拟出20世纪PDO"马蹄形"海表温度距平,其中BNUESM,CanESM2,CCSM4,CESM1-FASTCHEM,GFDL CM3,MIROC5,NorESM1-M等模式和中国科学院大气物理研究所的FGOALS-g2模拟的PDO太平洋海表温度遥相关型空间分布与观测相似度较高;耦合模式模拟的PDO时间序列与观测相差较大,表明现有的耦合模式几乎不能模拟出20世纪PDO的位相演变特征。
