Antarctic sea ice rotation: the dominant role of the atmosphere

In a recent study, Wayne de Jager and Marcello Vichi examined the relationship between Antarctic sea ice rotation and atmospheric conditions. 

They found that short-term weather events, such as storms and high-pressure systems, influence ice rotation on a daily basis and have a cumulative effect over a month. 

Over the past 30 years, sea ice has become more responsive to surface winds, though no clear trends were observed in either ice or atmospheric rotation, suggesting additional influencing factors. 

Their findings reinforce the atmosphere's dominant role in controlling Antarctic sea ice rotation but raise questions about the ocean’s influence on sea-ice rheology.
