Summertime sea-ice prediction in the Weddell Sea improved by sea-ice thickness initialization
Abstract Skillful sea-ice prediction in the Antarctic Ocean remains a big challenge due to paucity of sea-ice observations and insufficient representation of sea-ice processes in climate models. Using a coupled general circulation model, this study demonstrates skillful prediction of the summertime...
