MatLab code for Resonant Triads.

This is the MATLAB program for solving the barotropic potential vorticity equation to study the dynamics of resonant Rossby triads.

BPVE.m: This is a self-contained MATLAB program for solving the BPV equation. Please note that it takes a considerable time to run. For a quick test run, re-define the parameter DAYLEN=1.

You need to save the program in a file called, say, triads.m (shift-click on the links) and then run "triads" in MATLAB.
Different initial conditions are selected by re-defining ICtype. The default in the code is ICtype==7, to generate a star-shaped pattern.
