pdf:docinfo:title: Evaluation of a Regional Coupled Ocean ? Atmosphere ? Sea-Ice Model System over Greenland and the Arctic
xmp:CreatorTool: Prinect Printready
dc:description:  Rapid changes in key climatic indicators such as sea ice, seasonal snow cover, and glacier and ice sheet surface mass balance show that the Arctic is a region in transition. Understanding the feedbacks and processes requires a wide range of data, observations and model studies. Here we introduce a high-resolution coupled regional model system that describes ocean, atmosphere, ice sheet and sea ice processes in the Arctic Ocean and North Atlantic, with special focus on the area around Greenland. The system has been developed using the regional climate model HIRHAM5 and a fully coupled version of the ocean model HYCOM and the sea ice model CICE. We use the models in offline and coupled mode for a two-year experiment to examine the relative importance of ocean and atmospheric forcing and internal dynamics, as a first step towards investigating the recent rapid decline of Arctic sea ice and low surface mass balance of the Greenland Ice Sheet. The model setup can successfully reproduce the seasonal variability in sea-ice extent and highlights the bounds of internal variability in the system, while Greenland Ice Sheet surface mass processes are well represented.
