DTDM (Dynamics and Thermodynamics Demonstration Model)

DTDM is a very simple, two-dimensional code that can be used to demonstrate concepts relating to gravity waves and buoyancy oscillations, circulations resulting from differential heating, heat and cold sources and cold pools, etc., with potential utility for classroom demonstrations and homeworks.  The model is Fortran-based and produces GrADS output.  Please read the disclaimer.
