摘　　要：本文利用来自ECMWF的ERA-40 wavereanalysis海浪资料,分析了北大西洋海浪场与NAO(北大西洋涛动指数)的关系。研究发现如下主要特征:北大西洋海域的海表风场和(风浪、涌浪、混合浪)浪场与NAO(北大西洋涛动)有着密切的关系,且存在3.71年左右的共同周期。In this paper,the relationship between NAO index and wave field,wind field in the North Atlantic Ocean during the last 43 years were analyzed.The research shows that there is a close relationship between NAO index and wave field,wind field,and they have the same period of 3.71 years.
