WebViegas (2006) showed that only if R' ≈ 1 the behavior of a fire can be considered as static as its properties remain constant. If the value of R' is large, the acceleration of the fire front can be quite large and lead to what we designate as Extreme Fire Behavior that is normally associated to rapid changes of the ROS and to large values of fire line intensity. WebWhen fire moves upslope, the fuel ahead of the flame front is closer to the flame than if the slope were flatter. This set-up "preheats" the fuels. The effects of slope on fire spread …
