| Abstract: |
This report documents the development and testing of the LES (Large Eddy Simulator) version of the WRF (Weather Research and Forecasting) model coupled with SFIRE, the wildland surface fire module, to simulate wildland fires. The relevance of this work to NIST's WFDS (WUI [Wildland Urban Interface] Fire Dynamics Simulator) is to evaluate the impact of specified atmospheric conditions, topography, domain configurations, and boundary conditions on coupled atmosphere/wild fire model results. Once ignited, the most important environmental property to wild fire behavior is the evolution of the interaction of the fire plume with the ambient wind. As an operational field model, the WFDS must have access to a real-time forecast of atmospheric boundary layer flow. As an operational field model, the WFDS must be able to simulate atmospheric boundary layer flow in the fire domain. |
