Comparing Numerical Accuracy of Icosahedral A-Grid and C-Grid Schemes in Solving the Shallow-Water Model

A single software framework is introduced to evaluate numerical accuracy of the A-grid (NICAM) versus C-grid (MPAS) shallow-water model solvers on icosahedral grids. The C-grid staggering scheme excels in numerical noise control and total energy conservation, which results in exceptional stability for long time integration. Its weakness lies in ...

Performance Comparison of the A-grid and C-grid Shallow-Water Models on Icosahedral Grids

Different methods of solving shallow water models on icosahedral grids were compared. Specifically, researchers examined the differences in accuracy from using unstaggered variables (A-grid, with mass and velocity at cell centers) compared to staggered variables (C-grid, with mass and velocity on cell edges). It was found that C-grid performs be...
