GeophysicalFlows.jl

This package leverages the FourierFlows.jl framework to provide modules for solving problems in Geophysical Fluid Dynamics on periodic domains using Fourier-based pseudospectral methods.

Installation

Modules

All modules provide solvers on two-dimensional domains. We currently provide

• TwoDNavierStokes: the two-dimensional vorticity equation.
• BarotropicQG: the barotropic quasi-geostrophic equation, which generalizes TwoDNavierStokes to cases with topography and Coriolis parameters of the form f = f₀ + βy.
• BarotropicQGQL: the quasi-linear barotropic quasi-geostrophic equation.
• MultilayerQG: a multi-layer quasi-geostrophic model over topography and with the ability to impose a zonal flow U_n(y) in each layer.
• SurfaceQG: a surface quasi-geostrophic model.
