Abstract

This is a finite-difference, two-layer, quasi-geosotrophic model. The governing equations are the conservation of potential vorticity in each layer with added viscous terms and forcing (Pedlosky, 1987). This model simulates the dynamics of mesoscale currents. The nonlinear term is discretized with Arakawa energy, enstrophy and symmetry conserving scheme. Doubly-periodic boundary conditions are applied. To compile, please, type "make all".
