2013), The impact of an intense summer cyclone on 2012 Arctic sea ice retreat, Geophys
[1] This model study examines the impact of an intense early August cyclone on the 2012 record low Arctic sea ice extent. The cyclone passed when Arctic sea ice was thin and the simulated Arctic ice volume had already declined ~40 % from the 2007–2011 mean. The thin sea ice pack and the presence of...
