Title: Forecasting of Fire Weather and Smoke Using Vegetation-Atmosphere Interactions

Project Proposal Abstract: Reliable forecasting of regional weather and wind flow patterns is critical for effective fighting of wildiand fires and the operational management of prescribed bums. Accurate prediction of future wind fields is essential for predicting fire behavior; smoke dispersion, and mitigation of public health risks. Regional weather forecasts are currently produced by 3D mesoscale simulation models, which are quite sensitive to lower boundary conditions defined by the surface exchange of heat and water vapor between terrestrial ecosystems and the atmosphere. These exchange processes are poorly described in current meso-models. This causes great uncertainties in the weather predictions beyond 10 hours. Hence, improving the biophysical representation of land- surface processes in meso-models might be a key step towards a more accurate forecast of fire weather and airflow. Based on this notion, we propose to: 1) Significantly improve the weather forecasting capabilities of the MM5 mesoscale model by coupling it with a detailed biophysical model of soil-vegetation-atmosphere interactions called FORFLUX; 2) Use the coupled MM5- FORFLUX model to provide real-time operational weather forecast over a large portion of the Western US at 12-km and 4-kin spatial resolution; 3) Provide improved real-time predictions of wind fields to fire-spread and smoke-dispersion simulators currently being developed at the FS Fire Science Laboratory in Missoula MT; 4) Deliver the forecast products on the Web in a user-friendly and operationally usable form to fire behavior specialists and land managers. The proposed research will use tools, hardware, and information infrastructure developed and supported by other FS Programs such as the Fire Consortia for Advanced Modeling of Meteorology and Smoke (FCAMMS).
