How does wind influence fire behavior?

• A. Wind provides oxygen, increases rate of spread, tilts flames, drives spotting, and raises fire intensity.
• B. Wind cools the flames and reduces spread.
• C. Wind has no effect on spotting.
• D. Wind only changes direction but not intensity.

Answer: (C)

Wind strongly influences fire behavior by delivering oxygen to the flame, pushing heat and flames toward unburned fuels, and increasing how quickly the fire spreads and how intense it is. It tilts the flames, which concentrates radiant heat on nearby fuels and speeds ignition. Wind also carries burning embers and debris, causing spotting ahead of the main fire and creating new ignition points. In addition, wind determines the direction of spread and can cause sudden changes in fire movement with gusts. In short, wind doesn’t just blow; it actively fuels, directs, and magnifies a fire’s growth.
