A53C:
Polar Climate and Predictability II Posters


Session ID#: 9029

Session Description:
Accurate polar climate prediction on seasonal to multidecadal timescales could benefit a wide range of stakeholders, from local residents to governmental policy makers. However, few modeling studies have predicted recent changes in the Arctic or Antarctic with fidelity. In this session, we seek studies that identify sources of predictability, evaluate causes of variability, and characterize uncertainty in polar climate prediction using a broad range of approaches. Studies that evaluate relevant observational products and assess model error are necessary for better predictions in the future. In addition, we welcome studies that link polar climate predictability to extrapolar phenomena. This session aims to connect scientists across a wide range of disciplines – those studying land ice, sea ice, ocean, atmosphere, and their coupling – whose research has furthered our understanding of Arctic or Antarctic climates.
