Description
In this work, I present a semi-Lagrangian solver for the spherical Shallow Water Equations, written in vorticity-divergence form. The solver makes use of a Biot-Savart law to compute the velocity, and is discretized on a tensor product Chebyshev grid on the cubed sphere. I also discuss some advantages and difficulties associated with using a semi-Lagrangian discretization, as well as the vorticity-divergence formulation of the SWE.
