This session aims to showcase recent research progress and augment existing knowledge in polar meteorology and climate, and the atmosphere-land ice-sea ice coupling in both Hemispheres. It will provide a setting to foster discussion and help identify gaps, tools, and studies needed to address these open questions. It is also an opportunity to convey newly acquired knowledge to the community.
We invite contributions on all observational and numerical modelling aspects of Arctic and Antarctic meteorology and climatology that address atmospheric interactions with the cryosphere. This may include but is not limited to studies on past, present and future of:
- Atmospheric processes that influence sea ice (snow on sea ice, sea ice melt, polynya formation and sea ice production and transport) and associated feedbacks,
- Surface energy balance above the snow/ice surface.
- The variability of the polar large-scale atmospheric circulation (such as polar jets, the circumpolar trough and storm tracks) and impact on the cryosphere (sea ice and land ice),
- Atmosphere-cryosphere interactions triggered by synoptic and meso-scale weather phenomena such as cold air outbreaks, katabatic winds, extratropical cyclones, polar cyclones, atmospheric rivers, Foehn winds, and heatwaves,
- Role of clouds in polar climate and impact on the land ice and sea ice through interactions with radiation,
- High-latitude dust and pollution, deposition on snow and ice, and related impacts.
- Teleconnections and climate indices and their role in land ice/sea ice variability.
Presentations including new observational (ground- and satellite-based) and modelling methodologies specific to polar regions are encouraged. Contributions related to results from recent field campaigns in Greenland, the Arctic, and in the Southern Ocean/Antarctica are most welcome.
