GC31A:
Advancing Science of the Arctic System: Exploring the Past and Present to Predict the Future I Posters


Session ID#: 8314

Session Description:
While some of the largest impacts arising from climate change are expected to occur in the Arctic, there remain many gaps in our understanding and representation of critical processes in models of the Arctic system. The IARPC Science Plan identifies some necessary steps for model improvements that may lead to improved projections of variability in sea ice, snow cover, ocean, atmosphere and land states. An integrated and coordinated effort is required to improve the fidelity of Arctic system models, their capability to project future changes, and to enable informed use of those projections.

We solicit papers that advance understanding of the Arctic system through simulation and comparison of global and regional climate models with observations of the past and present behavior of the Arctic system. We also solicit presentations that identify and evaluate individual parameterizations, model components, and coupled feedbacks that control variability and affect uncertainty in Arctic climate predictions.
