Description
Summary:During 2021, and following on from 2020, net Antarctic sea ice coverage continued to exhibitstrong variability (Fig. 6.11a), with distinct regional and seasonal contributions (Fig. 6.11b). Theyear began with below-average overall sea ice extent (SIE) in January through February (Fig.6.11a), compared to the 1991-2020 average, but abruptly switched to above average in late Februarywhere it remained almost continuously until early September.
