High-Resolution Climate Modeling
Session ID#: 85056
Session Description:
High-resolution (HR) climate simulations that either permit or explicitly resolve eddies in the oceans and tropical cyclones in the atmosphere have gained significant momentum over the last few years. Such HR simulations are necessary to assess and quantify the role of fine-scale ocean features, including fronts, eddies, and filaments, and their interactions with the atmosphere and sea-ice in climate variability and prediction. Specifically, improving our understanding of how multi-scale interactions arising from coupling the better resolved atmosphere and ocean models influence the low-frequency, large-scale behavior of the Earth system has important implications for advancing our predictions of the natural climate variability with important societal benefits. Despite progress, there are many challenges associated with HR climate modeling that include model evaluation, data volume and processing, computational performance, and model initialization. This session invites presentations on all aspects of HR climate modeling, including studies from field programs and coordinated HR modeling projects. Studies on observational data and metrics that can be used for evaluation of HR simulations and on efficient diagnostics tools for analysis of large data are particularly encouraged.
