Synoptic weather systems over Antarctic sea ice: understanding the link between extratropical cyclones and extreme variability in Antarctic sea-ice concentration by Hepworth, Ehlke

“…Whilst the use of ERA5 revealed an emphasis on intense cyclones engendering extreme variability, the results derived from the analysis using CCAM showed that extreme variability in sea-ice concentration only depended on cyclone intensity in the East Antarctic sector. …”
