Abstract: The properties of C-grid staggered spatial discretizations of the shallow-water equations on regular Delaunay triangulations on the sphere are analyzed. Mass-conserving schemes that also conserve either energy or potential ...

Abstract: The idealized test case proposed by Held and Suarez is carried out with the atmospheric general circulation model ECHAM5 of the Max Planck Institute for Meteorology. The aim is to investigate the sensitivity of the solutions ...

Abstract: A representation of the orography based on approximate finite-volume techniques is applied to a nonhydrostatic atmospheric model. Techniques previously developed by the authors in the context of a semi-implicit, semi-Lagrangian ...
