Modeling wildfire behavior requires extensive vegetative analysis, dymanic moisture and wind inputs and slope, aspect and elevation inputs

This overall wildfire hazard and risk analysis for a southern California city, mapped above, relies heavily on wildfire behavior analysis. The dark reds and browns show the most extreme risk and hazard areas, which don't necessarily correspond with the hazard from fuels analysis alone. Factoring in fuels, historic fires and weather and wind vectors, gives more insight into fire behaviors such as flame length, rate of spread and fire crowning to depict the severity of probable fires. The overall hazard and risk analysis, however, accounts for factors such as available firefighting resources and structures at risk.

Wildfire behavior modeling

FUEL CATEGORIZATION is often the most important element of modeling wildfire behavior, but the Anchor Point Group also uses historic wildfire and weather information with information on slope, aspect and elevation to help determine fire behavior. APG models also integrate information on WIND VECTORS, which depict how direction and strength can compound or diminish hazard under specific scenarios. All these add up to a state-of-the-art model giving firefighters precise information on fire specifics, such as FLAME LENGTH and RATE OF SPREAD in dynamic models that can including variables such as fuel moisture andwind speed and direction. These attributes, together with information on structures and probability of ignition, can DRAMATICALLY CHANGE THE OVERALL WILDFIRE RISK RATING. To restore the original image, click here.
