The Model for Prediction Across Scales (MPAS) is jointly developed by the Los Alamos Laboratory and the National Center for Atmospheric Research (NCAR). It consists of three parts, called MPAS-A (Atmospheric Model ), MPAS-O (ocean model) and MPAS-LI (land ice model). The initial purpose of MPAS was to build a new earth system model that can be used for global or regional weather and climate research. This training focuses on the atmospheric model MPAS-A. The atmospheric dynamic kernel of the MPAS-A model solves the fully compressible non-static equations of motion, and its most notable feature is the unstructured centroid Voronoi grid. The SCVT grid provides an opportunity for regional downscaling within a global framework (below), as it allows a smooth transition of the grid from coarser to higher resolutions, rather than the traditional method of translating grids using nesting Regional climate models RCM (eg WRF).
The MPAS-A model is being continuously optimized. Due to its advanced model structure and variable resolution grid characteristics, it will be one of the main trends in high-resolution simulation in the future.
