Summary This project will apply the Regional Arctic System Model (RASM) at process resolving configurations to (i) advance understanding of physical processes and feedbacks involved in Arctic amplification of global climate change and (ii) understand and potentially reduce uncertainty in predict ion of arctic climate change at seasonal to decadal scales. The project's main goal is to match arctic surface climate sensitivity to particular processes and space-dependent parameters and identify spatio-temporal changes in these relationships using a hierarchy of models evaluated against observationally based metrics. The project builds upon successful research by the PIs with support from the following program s: DOE Regional and Global Climate Modeling, ONR Arctic and Global Prediction and NSF Office of Polar Programs. Finally, we will run seasonal to decadal predictability studies with RASM ensembles generated using CESM 21st century decadal scenarios. This project will address increasing societal needs for improved arctic seasonal to decadal climate predictions. It will facilitate further progress in arctic climate change prediction by optimizing parameter space in key physical parameterizations for improved climate simulation and prediction at increasing spatial and temporal resolutions. It will capitalize on the synergy between the development of regional and global climate models and their use in the assessment and attribution of arctic climate variability.
