A 30 arcsec (approximately 900 m) resolution physical model of the northeastern Gulf of Mexico (BBR) has been developed using the Regional Ocean Modeling System (ROMS) (Fig. 14). The model topography and coastline geometry has been hand-edited to provide for representation of major estuaries and fifteen river sources have been implemented. Scripting tools have been developed to acquire and process real-time atmospheric model data for the ocean simulation. Data processing tools have been developed for automation of river gauge raw data acquisition, quality control, and detiding for use as real-time forcing for the ocean model. Under a state-funded project, the HYbrid Coordinate Ocean Model (HYCOM) has been configured at 1/25° resolution for the Gulf of Mexico and adjacent western Atlantic waters and is run in near real-time with data delivered via a server at COAPS. This model is providing boundary conditions to the Northeastern Gulf of Mexico ROMS simulation.

The Advanced Research WRF (Weather Research and Forecasting) atmospheric model has been configured for a comparable domain at 1.33km resolution, and, similar to the ocean modeling strategy, is embedded within a 4km model domain covering the Gulf of Mexico and western Atlantic developed under a state-funded project. The model is intended to be coupled to the ROMS ocean model for the region and is currently being used to study the coastal sea breeze circulation and cold air outbreaks over the ocean.
