What are five weather elements that affect wildland fire behavior?
Weather conditions such as wind, temperature, and humidity also contribute to fire behavior. Wind is one of the most important factors because it can bring a fresh supply of oxygen to the fire and push the fire toward a new fuel source.
How does temperature and relative humidity affect wildland fire behavior?
Some might say that relative humidity is most important but we will learn that temperature drives relative humidity. Fuel temperatures also affect a fire�s rate of spread. Warm fuels will ignite and burn faster because less heat energy is used to raise the fuels to their ignition temperature.
Which topographical aspect of a wildland fire is typically most active?
Under normal conditions, a north facing aspect will have more fire activity than a south facing aspect.
Does low humidity increase spot fires?
CHICO, Calif. – Low humidity often accompanies strong downslope winds which increase fire danger.
What are two effects of air movement in relation to fire behavior?
Wind increases fire spread by carrying heat and burning embers to new fuels (spotting). Wind bends the flames closer to the unburned fuels, pre-heating the fuels ahead of the fire front. Changes in wind direction and speed can rapidly change fire behavior from inactive to active.
What is the fastest growing part of a wildland fire?
Head of a Fire: The side of the fire having the fastest rate of spread. Heavy Fuels: Fuels of large diameter such as snags, logs, large limb wood, that ignite and are consumed more slowly than flash fuels.
What is the fastest spreading part of a fire?
Head
Head of a Fire: The side of the fire having the fastest rate of spread.
What does the E in Lces stand for?
‘LCES’ stands for Lookouts-Communications-Escape routes-Safety zones. The elements of LCES form a safety system used by wildland firefighters to protect themselves from entrapment from free-burning wildfires and other fireline hazards.
