AB: The Gulf costal states region is prone to the highest national frequency to severe weather accompanied by huge economic loss. The region lacks adequate study with regard to significant coastal processes - "weather dynamics". Understanding modeling and predicting the coastal processes and dynamics is important in improving weather forecasting. A mesoscale modeling investigation of tropical cyclone\/hurricane forecast over the Gulf of Mexico has been undertaken pertaining to NOAA's interest to assess and predict environmental changes, protect life and property and provide decision makers with reliable scientific information. In the present study the Weather Research and Forecasting \(WRF\) model is run on a high performance computing environment using non-conventional datasets. Data from the PennState\/NCAR MM5 v.3 model is fed into the WRF v.1.3 model as initial and lateral boundary conditions to simulate the surface features of a case oriented 2003 landfalling hurricane. Simulation parameters include seal level pressures, surface fluxes, sea surface temperature, wind direction and magnitude, and precipitation. The results will be compared with aircraft observations taken by the National Hurricane Center. This model output is then incorporated into a decision support matrix. The results of the model simulations will be presented and discussed.
