IPCC AR4모형에서 전망한 북태평양 혼합층깊이 변화 전망

Abstract

Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4). The MLDs in the Kuroshio Extension (KE) consistently decrease up to 50 % by the end of 21st century in almost all the models examined. The MLD change in the western subploar region, on the other hand, varies significantly depending on models. The upper ocean stratification measured by the buoyancy frequency intensifies in the north Pacific, which mainly caused by surface freshening and warming. The KE front shifts northward in response to the wind stress curl shift, which provides an additional factor in understanding the spatial pattern of the MLD changes. These results suggest that changes in the wind stress and ocean circulation
