Which factor contributes to increased fire intensity?

High winds significantly contribute to increased fire intensity by enhancing the fire's ability to spread rapidly. Wind serves as a vital component that can feed a fire by supplying additional oxygen, which is essential for combustion. Strong winds can also lift and carry embers and flames, allowing the fire to jump to new areas and ignite spot fires far beyond the original blaze. This results in a quicker progression of the fire and often leads to more intense flames and higher temperatures.

In contrast, factors such as increased humidity, cooler temperatures, and stable atmospheric pressure tend to create conditions that can either suppress or slow down fire activity. Increased humidity can dampen fuel moisture content, making it harder for fires to ignite and spread. Cooler temperatures decrease the rate of combustion and can lead to reduced fire activity. Stable atmospheric pressure does not contribute to wind patterns that would fuel a fire, making it less impactful on fire intensity compared to wind.
