近43年北大西洋海浪场与AO的相关性研究
The relationship between AO index and ocean wave in the North Atlantic Ocean during the past 43 years
摘要
Abstract
Based on the ERA-40 wave reanalysis from ECMWF, the relationship between Arctic Oscillation (AO) index and ocean wave in the North Atlantic Ocean in the past 43 years were analyzed,. The result shows that there is a close relationship between AO index and wave field, and they have the same period of 3.71 years and 26 years long periodic oscillation. It is found that the elements mentioned above is significantly in the wave number of k=7 (the period of 3.71 years) by cross spectrum analysis, and there are some certain lead-lag relations among the different elements.关键词
