Sensitivity Study, Analysis and Improvement of the Eddy-resolving Regional Arctic System Model (RASM-er)
Abstract
The Arctic Ocean and its sea ice cover have recently experienced dramatic changes. In the summer of 2007 (Comiso et al., 2008) and 2012 (Parkinson and Comiso, 2013, Zhang et al., 2013) sea ice extent recorded minima and the scientific community agrees that we are facing ice-free summers in the coming decades (Wang and Overland, 2009). One of the most important tools to understand, diagnose and predict future Arctic climate changes are numerical models, such as the Regional Arctic Climate System Model (RASM). Unfortunately, up-to-date such models are rather limited in their ability to resolve small-scale yet critical physical processes and interactions, which may influence or even determine the large scale and long-term behavior of the Arctic System. In this project, Dr. Robert Osinski from the Institute of Oceanology of Polish Academy of Sciences (IOPAS) will contribute to the ongoing RASM development and modeling studies at the Naval Postgraduate School led by Professor Wieslaw Maslowski and funded by the Office of Naval Research, Department of Energy and National Science Foundation. The IOPAS contributions will focus on (i) model sensitivity to scale-dependent parameterizations using the eddy-resolving RASM (RASM-er) configuration, (ii) analysis of model results on sea ice, ocean and the surface atmosphere-ice-ocean interface and their synthesis with observations, and (iii) model optimization and improvement based on findings from those investigations. This research will contribute to societal understanding of the Arctic system and will improve and allow advanced capabilities for Arctic environmental prediction, hence it is of high relevance to the U.S. Navy and DOD as well as to the general public.
