Spectral interpolation in semi-implicit semi-Lagrangian methods for shallow water equations on the sphere
Michael Chiwere, Daniel Fortunato, Grady B. Wright
Semi-implicit semi-Lagrangian (SISL) methods are commonly used for the shallow water equations (SWE) because they allow for larger time steps than those permitted by the Courant-Fr…

Barycentric interpolation formulas for the sphere and the disk
Michael Chiwere, Grady B. Wright
Spherical and polar geometries arise in many important areas of computational science, including weather and climate forecasting, optics, and astrophysics. In these applications, t…
