This is an experimental high resolution WRF model running at approximately 4 km horizontal resolution. For a description please see: http://wrf-model.org/index.php

We run the model non-hydrostatically using a cluster of 2 -Dual 2.4 GHZ Xeon Processor Linux machines with 1GB RAM with:

- A 251x239 grid centered at 74.8W 40.5 N
- A 1 degree GFS dataset for the initial and lateral boundary conditions to initialize the model.
- A 0.5 degree High Resolution Sea Surface Temperature(SST) dataset.
- A 30-second land-sea mask for high resolution depiction of coast shorelines.
- No (convective) cumulus paramaterization.
- The New Ferrier Microphysics Scheme            
- The Mellor-Yamada-Janjic Boundary Layer scheme            
- The NMM Land surface scheme .                         
- The GFDL long wave radiation scheme      
- The GFDL short wave radiation scheme

- The output is available at 1-h forecast increments to 30-hr and is run 4 times a day.
- We use GEMPAK 5.9 to create the graphics to post to the web page.

We expect to use the model qualitatively to help refine phenomena related to terrain and marine influence. Things like orographically forced precipitation and sea breeze fronts seem to be handled well in a general sense, but the exact placement and magnitude of weather features is not expected to be perfect, as is the case with any model. It should, however, give some clues about how complex terrain can affect the atmosphere.

This is an experimental and research model that is not supported operationally. It may not always be available, may have errors, or be changed without notice to support local research and model experimentation.
