WindWizard is no longer supported by the Missoula Fire Sciences Lab as the underlying software is not readily available. Much of the computational fluid dynamics (CFD) modeling within the WindWizard framework was added to the WindNinja software.

Microscale wind simulator using computational fluid dynamics (CFD) software.

WindWizard is a computer model designed to calculate the effect of topography on local wind flow. Outputs from the model are wind speed and direction every 100-300ft over the terrain. Simulations can be completed on a laptop computer in about 1 hour. Wind information at this detail is not available from the weather service. The wind simulations are not forecasts but rather simulations of what the wind flow would be under different general (synoptic) wind speed and direction scenarios.

The User can essentially pick the scenario they want to simulate; it might be based on forecasts, local observations or historical weather patterns. This high resolution wind information has been used to identify areas and/or conditions that may produce high fire intensity and spread rates and for identifying locations where fire spotting might occur. It also increases the accuracy of FARSITE predictions.
