a 10-yr mean SIC anomalies (color in %) observed during 2008–2017. Black boxes indicate the Amundsen–Bellingshausen Sea (120°−60°W, 70°−60°S) and Weddell Sea (60°−0°W, 65°−55°S). We calculated the anomalies with respect to the period of 1982–2018. b–d Same as in a, but for the 10-yr mean SIC anomalies (in %) predicted from March 1st 2008 in the CTL, SIR, and 3DVAR experiments.
