A Scalable Spectral Element Eulerian Atmospheric Model (SEE-AM) for NWP: Dynamical Core Tests

Abstract

A new dynamical core for numerical weather prediction (NWP) based on the spectral element method is presented. This paper represents a departure from previously published work on solving the atmospheric primitive equations in that the horizontal operators are all written, discretized, and solved in 3D Cartesian space. The advantages of using Cartesian space are: the pole singularity which plagues the equations in spherical coordinates disappears; any grid can be used including lat-lon, icosahedral, hexahedral and adaptive unstructured grids; and the conversion to a semi-lagrangian formulation is easily achieved.
