Modeling Arctic Ocean heat transport and warming episodes in the 20th century caused by the intruding Atlantic Water
Abstract This study investigates the Arctic Ocean warming episodes in the 20th century using both a high-resolution coupled global climate model and historical ob-servations. The model, with.no flux adjustment, reproduces well the Atlantic Water core temperature (AWCT) in the Arctic Ocean and shows...
