The IASC Atmosphere Working Group has organized a session at the Fall Meeting of the American Geophysical Union that deals with Coupled Processes in the Arctic System: Feedbacks, Amplification, and Impacts on Mid-latitudes. Through multiple feedbacks and amplification processes, Arctic Changes are occurring earlier than anticipated from anthropogenic contributions alone. These interactions are occurring between atmosphere,permafrost, vegetation, hydrology, geomorphology, biogeochemistry, snow, clouds, sea and glacial ice, and the oceans over a range of space and time scales. These changes are also beginning to impact sub-Arctic oceans, land, and atmospheric circulation. The session organizers welcome observational, theoretical, and numerical studies focused on emergent, nonlinear, and threshold dominated amplification processes and teleconnections.
