Geophysical fluid dynamics pseudospectral solvers with Julia and FourierFlows.jl.

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

To install, do

] add GeophysicalFlows

Examples

See examples/ for example scripts. These examples are best viewed by browsing them within the package's documentation.

Some animations created with GeophysicalFlows.jl are online @ youtube.

Modules

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

• TwoDNavierStokes: the two-dimensional vorticity equation.
• SingleLayerQG: the barotropic or equivalent-barotropic quasi-geostrophic equation, which generalizes TwoDNavierStokes to cases with topography, Coriolis parameters of the form f = f₀ + βy, and finite Rossby radius of deformation.
• 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.
