Researchers in China developed a series of high-resolution coupled Earth system models (SW-HRESMs) with up to 5 km of atmosphere and 3 km of ocean which can meet the needs of multiscale interaction studies with different computational costs. They described the progress of SW-HRESMs development, with an overview of the major advancements made by the international Earth science community in HR-ESMs. They showed the preliminary results of SW-HRESMs regarding capturing major weather-climate extremes in the atmosphere and ocean, stressing the importance of permitted clouds and ocean submesoscale eddies in modeling tropical cyclones and eddy-mean flow interactions, and paving the way for further model development to resolve finer scales with even higher resolution and more realistic physics. In addition to increasing model resolution, the development procedure for a non-hydrostatic cloud and ocean submesoscale resolved ESM was discussed, laying out the major scientific directions of such a huge modeling advancement… read more.
