Atmospheric winter response to a projected future Antarctic sea-ice reduction: a dynamical analysis
Several studies have analysed the atmospheric response to sea-ice changes in the Arctic region, but only few have considered the Antarctic. Here, the atmospheric response to sea-ice variability in the Southern Hemisphere is investigated with the atmospheric general circulation model ECHAM5. The mode...
