Real-Time Modeling

John Nielsen-Gammon and Gerry Creager are running the MM5 and WRF models in real-time for high-resolution forecasts of Texas and the US coastal regions along the Atlantic and Gulf of Mexico. The model is being used for air quality and coastal circulation forecasts.


Parameter Estimation

John Nielsen-Gammon and colleagues are using Ensemble Kalman Filtering as a tool to improve the parameterizations of mesoscale meteorological models. By allowing data assimilation to affect the parameters that control the behavior of a parameterization, the model can dynamically adjust its parameterization so that its forecast is more accurate.


Storm Structure and Baroclinicity

Courtney Schumacher is using disdrometer and radar measurements in Southeast Texas and mesoscale model output to determine the role environmental baroclinicity plays in storm microphysics and divergence profiles.
