Topics:
Vorticity field
<p><em>Vorticity field of the horizontal flow field at 6 days of simulation of a barotropic instability test case for 3 different grid layouts, all with a nominal resolution of a quarter degree but with increased spectral order in an element of 4, 8, and 16 (top to bottom). Note the fine scale structure and noisiness of the fluid flow seen in both the explicit and implicit integration methods.</em></p>

MULTISCALE is a SciDAC Earth System Modeling project with the primary goal of producing better climate models to serve as the scientific tools and predictive tools that will address the needs of both the climate sciences and policy-oriented communities. Here are notable features of MULTISCALE: (1) Grand challenges in projecting the future of the Earth's climate result from the interactions among small-scale features and large-scale structures of the ocean and atmosphere in climate models. (2) A generation of models that capture the structure and evolution of the climate system across a broad range of spatial and temporal scales is required. MULTISCALE is an integrated team of climate and computational scientists working to accelerate the development and integration of multiscale atmospheric and oceanic parameterizations into the Community Earth System Model (CESM).

MULTISCALE is jointly funded by the Biological and Environmental Research (BER) and Advanced Scientific Computing Research (ASCR) programs in the U.S. Department of Energy Office of Science.
