Course Outline

Winds affect fire intensity, direction and rate of spread in several important ways:

  • By increasing the supply of oxygen, thus aiding combustion
  • By driving convective heat into adjacent fuels, hastening the drying process
  • By influencing the direction of spread and spotting
  • By bending flames closer to unburned fuels, preheating, drying and igniting them
  • By carrying away moist air, replacing it with drier air
  • By carrying embers to new fuels and increasing fire spread
  • By moving moist air that may reduce fire intensity
