Parameterization of Gravity Wave Mean-Flow Forcing

We have a parameterization that can be downloaded here. Versions written in both Fortran ("gwdrive.F" and sample input file "skyhi_in.dat") or IDL (gwdrive.pro) are available. This parameterization is suitable for application to GCMs or other coarse-resolution global models, or for mechanistic wave drag studies. For reference see Alexander and Dunkerton, 1999.

Fortran Version: gwdrive.F
with accompanying example data file: skyhi_in.dat

IDL Version: gwdrive.pro

Some studies using the parameterization include:
