I am working on methods for locally increasing model
resolution in the atmospheric dynamical core. The two primary
methods for doing this are grid nesting and grid stretching. These
techniques will allow the GFDL atmospheric model to be run at a
very high resolution over a limited area for use in hurricane
forecasting, long-range chemical transport, seasonal prediction,
and regional climate modeling.
 More information is available here.

I also have a few nice GrADS scripts, along with examples, that I use for some of my work that others may find helpful.

Ray Pierrehumbert’s classic essay on mountain gravity-wave drag parameterization is difficult to find online. A copy is available at ECMWF. Many other old ECMWF conference proceedings are available as well [broken as of 25 Feb 16]. A conference proceeding describing its use in the Miyakoda GFDL model, also hard to find, is available here.
