Changes in the Arctic and Antarctic climate system are strongly related
to atmosphere-ocean-ice (AOI) interactions. Phenomena such as the
dramatic decrease in sea ice extent in the Arctic over the past 30 years
contribute to rapid regional warming through feedbacks between the
atmosphere, ocean, and sea ice. On the other hand, Antarctic sea ice
variability is internally dominated with no strong multi-decadal trend.
Understanding and modelling these variations in the coupled AOI system
remains a challenge at both poles. AOI interactions are also associated
with synoptic weather systems and mesoscale extreme weather phenomena
such as cold air outbreaks, katabatic winds, and polar lows. In the
Arctic, for example, sea ice loss is associated with rapid regional
warming which is often tightly linked to mid-latitude weather and
climate. Arctic sea ice loss may also impact the state of the
stratospheric vortex, which in turn can affect the large-scale
hemispheric circulation in the troposphere. Furthermore, in the
Antarctic, sea ice change may affect ice shelf behaviour and hence could
affect sea level change. The representation of these physical processes
and interactions at different spatial and temporal scales, however,
remains a major challenge for current weather and climate models.
This symposium brings together researchers working in the areas of polar
meteorology and oceanography as well as sea ice to focus on physical
processes as well as on global change related to the Arctic and
Antarctic. Special emphasis is on the coupling between the ocean, ice,
and atmosphere and the interactions between the Polar Regions and the
large-scale hemispheric and global circulation. Further focus is on
processes and parameterizations related to physical exchange, including
the influence of sea ice floe-size distribution and sub-mesoscale
ocean/sea ice dynamics and thermodynamics. Contributions are welcome
dealing with theoretical and observational studies, including remote
sensing, as well as studies using numerical models.
