ECGRID
The ECMWF grid point barotropic shallow-water model according to some documents, such as Burridage,1977.
It is developed on regular latitude-longitude grid, and I also extend it both for u at poles and v at poles with Arakawa-C grid.
The following test cases are provided:
(1) Steady geostrophic flow (Williamson,1992)
(2) Mountain zonal flow (Williamson,1992)
(3) Rossby-Haurwitz wave (Williamson,1992)
(4) Cross pole flow (McDonald and Bates,1989)
(5) Jet_zonal_flow (Galewsky,2004)
