Abstract: A global nonhydrostatic semi-implicit semi-Lagrangian (SISL) atmospheric model with orography has been developed. The height-based terrain-following σz coordinate of Gal-Chen and Somerville is used to incorporate the ...

Abstract: A computationally efficient mass-conservative transport scheme over the sphere is proposed and tested. The scheme combines a conservative finite-volume method with an efficient semi-Lagrangian scheme based on the dimension ...

Abstract: A semi-Lagrangian semi-implicit finite-difference nonhydrostatic global atmospheric model on a flat terrain has been developed. Starting from the initialized ECMWF analysis of 0000 UTC 15 January 1979, a series of 5-day ...
