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 oceanβs influence on sea-ice rheology.

A key source of SSA is blowing snow, which releases particles into the air as it sublimates (turns from solid to gas).
During the MOSAiC Arctic expedition (2019β2020), researchers observed that blowing snow over sea ice significantly increased aerosol levels. These conditions occurred 20β40% of the time from December to April, with 26 events recorded. Strong winds were linked to higher sodium chloride levels in the air, confirming that storms help release SSA from blowing snow.
To improve climate models, Ananth Ranjithkumar et al. updated current model parameterization for blowing snow, adjusting factors like snow size and salt content based on wind speed and snow depth.
Including SSA from blowing snow in climate models will enable a more precise representation of aerosols in polar regions and helps improve climate predictions at high latitudes.

The Arctic & Antarctic are warming faster than the rest of the world, with the Arctic seeing sea ice loss, thawing permafrost, wildfires, & ecosystem shifts, while Antarctica faces ice sheet melt & marine ecosystems disruptions.
These changes have widespread effects on nature & society.
Adapting to the multitude and cascading impacts of Arctic change, within & beyond the regions requires coherent policy responses and cross-border cooperation.
