A Hamiltonian Particle-Mesh Method for the Rotating Shallow Water Equations
A new particle-mesh method is proposed for the rotating shallow-water equations. The spatially truncated equations are Hamiltonian and satisfy a Kelvin circulation theorem. The generation of non-smooth components in the layer-depth is avoided by applying a smoothing operator similar to what has recently been discussed in the context of $\alpha$-Euler models.
