The overall science goal of this project is to address the short to long-term US Navy / DOD (Arctic Roadmap, 2009) and national requirements (Roberts et al., 2010) to understand and predict arctic climate change. The proposed research leverages ongoing developments of the state-of-the-art Regional Arctic Climate Model (RACM) through a multi-institutional program supported by the Department of Energy Regional and Global Climate Modeling (DOE/RGCM) program and two ongoing complementary projects. This new project, which started in January 2012, is aimed at improved modeling of the atmosphere-ice-ocean interface in the presence of tides and eddies to advance representation of the past and present state of the Arctic Climate System and prediction of its future states at time scales from daily (operational) through seasonal, interannual, and up to decadal (tactical).
