Fig. 3

a The total Antarctic SIE anomaly for the time period 2011–2020 (shading) and the time-averaged (2017–2020) SIE anomalies (horizontal black line) in SPEAR_atm_restore. The brown lines denote the SIE time series and time-averaged (2017–2020) SIE anomalies in SPEAR_atm_restore_2015_newIC. b Same as (a) but for the Weddell Sea (50°W–10°E). Unit is 1012m2. The time-averaged SIE anomalies between two runs (horizontal black and brown lines) in (a) and (b) are signinficantly different at a 90% confidence level based on the Student’s t-test when we concatenate 5 ensemble members.
