Session ID#: 15671

Session Description:
The Arctic is undergoing some of the most coordinated and rapid climatic changes currently occurring anywhere on Earth. While historical reconstructions from Earth System Models (ESMs) are in broad agreement with these changes, the rate of change in ESMs remains outpaced by observations. This is due to a combination of coarse resolution, inadequate parameterizations, under-represented processes and a limited knowledge of physical interactions. Efforts, including those through IARPC coordination, are underway to advance understanding and improve fidelity of Arctic system models, their projections of future changes and societal use of those projections. We invite presentations that advance understanding of the Arctic system through observations or simulations of critical processes and their interactions that impact Arctic climate variability and trends. We also solicit papers on model-data syntheses and model intercomparisons, which identify and evaluate individual parameterizations, model components, and coupled feedbacks that affect uncertainty in predictions or predictability of Arctic climate.
