Fire Behavior is the way that fire acts in response to its environment. There are three primary drivers influencing fire behavior and together are referred to as the fire behavior triangle.
Weather – ignition conditions are stronger in higher temperatures, lower humidity, etc..
Fuels (vegetation) – ignition conditions are stronger in drier finer fuels
Topography – ignition conditions are stronger on steeper slopes which face more sun
This information is necessary for firefighters and people who manage land so that they can know the conditions for how fires start, limit fire spread, and stay out of harm’s way. Fires can respond rapidly to changes in these drivers so it’s important for scientists to better understand the relationship between fire behavior and the environment to provide firefighters and emergency responders with the most accurate information as fast as they can.
