[1] Trends in the satellite-derived Antarctic sea ice concentrations (1979–2002) show pronounced increase (decrease) in the central Pacific sector (Bellingshausen/ western Weddell sector) by 4–10 % per decade.

Positive polarities of the Antarctic Oscillation (AAO) lead to more (less) ice in the eastern Ross/Amundsen sector (Bellingshausen/northern Weddell sector), which are qualitatively opposite to the impacts of positive polarities of the El Niño-Southern Oscillation (ENSO). The mechanisms responsible for the covariability between the ice and the (a) AAO and (b) ENSO are demonstrated. Over the last 24 years, a positive AAO trend and a slightly negative ENSO trend produce a spatial pattern of ice changes similar to the regional ice trends.
