Influence of the NAO on the northwestern Mediterranean wave climate
10 pages, 10 figures. [EN] This study examines teleconnections between the North Atlantic Oscillation (NAO) and the wave climate of the northwestern Mediterranean Sea (NWM), defined by the monthly mean significant wave height (SWH) and the 95th percentile significant wave height (95th percentile SWH...
