10.4 MPAS: The model for prediction across scales

Skamarock, Bill, Michael Duda, Laura Fowler, Joe Klemp, and Sang-Hun Park, National Center for Atmospheric Research

We will present an update on MPAS, a global nonhydrostatic atmospheric model using global variable-resolution centroidal Voronoi meshes and much of the numerics and physics from the Advanced Research WRF model. MPAS provides a global-model complement to WRF and provides limited-area refinement without the issues associated with 1-way and 2-way nesting in WRF. We anticipate MPAS will be released shortly before this workshop.
