RISA Mass-Conservative, Positive-Definite, and Efficient Eulerian Advection Scheme in Spherical Geometry and on a Nonuniform Grid System
Publisher: American Meteorological Society
Abstract: The flux-form advection scheme of Bott is modified for the spherical coordinates, combined with the expanded-polar-zone (EPZ) technique to improve the overall performance of the advection calculations. With the EPZ technique, ...
