Interdecadal changes of tropospheric circulation in Southern extratropics during the recent warming in the Antarctic Peninsula
Summary An analysis of changes of atmospheric circulation in the Southern Hemisphere in relation to recent warming at the Antarctic Peninsula in last thirty years is presented. The sea level pressure and geopotential fields change in 1960-2000 are considered. It was shown that large-scale baric form...
