Description

Fire behavior model accuracy has suffered from a lack of specific information about how winds shift in direction and speed in mountainous terrain at fine scales. Before this project, fire managers lacked a tool that could provide real-time status of changing wind conditions at the scale of a specific ridge or drainage. This project resulted in two wind simulation tools that focus on this critical need: WindWizard and WindNinja, based on commercial computationsl fluid dynamics softward, comes with a price tag and is computationally slower due to the complexity of the calculations it performs. WindNinja was developed as WindWizard's lighter, faster, free, and more field-friendly cousin. Fire managers have found that these tools provide the reliable, timely, detailed information needed for informed fire management decisions, as well as valuable information about conditions leading to firefighter entrapments.
