A new algorithm is presented for the solution
of the shallow water equations on quasi-uniform spherical
grids. It combines a mimetic finite volume spatial discretization with a Crank–Nicolson ...

This paper applies the Hamiltonian Approach (HA) to two-dimensional motions of incompressible fluid in curvi-linear coordinates, in particular on a sphere. The HA has been used to formulate governing ...

We use a quasi-geostrophic numerical model to study the turbulence of rotating flows in a sphere, with realistic Ekman friction and bulk viscous dissipation. The forcing is caused by the destabilizati...
