What are the two most important weather-related elements affecting wildland fire behavior? Wind & Fuel Moisture.
What 3 weather factors are most important to wildland firefighters?
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.
What are two types of weather forecast products or services provided by predictive services?
Predictive Services consists of three primary functions; fire weather, fire danger/fuels, and intelligence/resource status information.
What are the weather elements the most important from the wildland fire standpoint?
What are the weather elements the most important from the wildland fire standpoint? The four critical weather elements that produce extreme fire behavior are low relative humidity, strong surface wind, unstable air, and drought.
What is the most common type of wildland fire?
What is the most common type of wildland fire? Ground cover: fires that burn loose debris on the surface of the ground. This debris includes vegetation such as grass, as well as dead leaves, needles, and branches that have fallen from shrubs and trees.
What are the 4 factors that affect weather?
Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.
What are the different types of general winds?
There are three types of wind that are associated with wildland fire: general winds resulting from atmospheric activity, local winds resulting from unequal heating of land and sea surfaces, and winds resulting from a fire’s buoyancy (also called entrainment).
What weather factor has the greatest impact on fire behavior?
Arguably, temperature, is the single most important weather factor affecting 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.
What two components of the Earth’s atmosphere are most important to wildland firefighting group of answer choices?
The two most important weather, or weather related, elements affecting wildland fire behavior are wind and fuel moisture. Of the two, wind is the most variable and the least predictable. Winds, particularly near the earth’s surface, are strongly affected by the shape of the topography and by local heating and cooling.
Why is forest rehabilitation important after a fire?
Controlling invasive species through both immediate and sustained actions can be a necessary post-fire restoration action. … Both immediate and continued efforts including reseeding and replanting with native species and long-term controls of non-native species will ensure native species once again thrive.
