The past few decades have seen dramatic progress in our understanding of solar interior
dynamics, prompted by the relatively new science of helioseismology and increasingly …

A latitude–longitude grid is used by almost all operational atmospheric forecast models, and
many research models. However, it is expected that the advantages of a latitude–longitude …

This report presents the details of the governing equations, physical parameterizations, and
numerical algorithms defining the version of the NCAR Community Atmosphere Model …

The Community Atmosphere Model (CAM) version 5 includes a spectral element dynamical
core option from NCAR's High-Order Method Modeling Environment. It is a continuous …

We present spectral element (SE) and discontinuous Galerkin (DG) solutions of the Euler
and compressible Navier–Stokes (NS) equations for stratified fluid flow which are of …

It is the purpose of this paper to provide a comprehensive documentation of the new NCAR
(National Center for Atmospheric Research) version of the spectral element (SE) dynamical …

We derive an implicit-explicit (IMEX) formalism for the three-dimensional (3D) Euler
equations that allow a unified representation of various nonhydrostatic flow regimes …

A deterministic initial‐value test case for dry dynamical cores of atmospheric general‐
circulation models is presented that assesses the evolution of an idealized baroclinic wave …

A new configuration of the Community Earth System Model (CESM)/Community Atmosphere
Model with full chemistry (CAM‐chem) supporting the capability of horizontal mesh …

We derive a formulation of the spectral element method which is compatible on very general
unstructured three-dimensional grids. Here compatible means that the method retains …
