Here is a list of the various numerical models we are using:
Idealized dry GCM
Based on GFDL FMS, it has been developped in Tapio Schneider's group at Caltech. It is available here, together with more complex models (moist, moist with a simple surface hydrology, etc...)
One and two layer GCM and cumulant expansion
The GCM has been developed by Brad Marston at Brown Univeristy and is described and available here.
Available upon request: fortran code calculating finite-time Lyapunov exponent and vectors and their statistics in two-dimensional flows. Example of output for a flow solution of the two dimensional barotropic vorticity equation:
