Slopes that face east and west receive more insolation than north-facing slopes, but less than south-facing slopes. When burning conditions are favorable, the heavier fuel loads can lead to increased However, in some cases, the ridge can provide From these few examples, we can see that atmospheric stability is closely related to fire behavior, and that a general understanding of stability and its effects is necessary to the successful interpretation of fire-behavior phenomena. (measured at 2-m above ground level) is above freezing, the snow These slopes tend to be located on the borders between individual waste disposal cells or phases in the landfill and extend to the height of the eventual final development slopes. Extinguishing or removing burning material near control lines, felling snags, and trenching logs to prevent rolling after an area has burned, to make a fire safe, or to reduce residual smoke. List the five general categories of sensory receptors.\ What does direct sunlight and hot temperatures in the wild land fire environment do to fuels? more sunshine, leading to drier and oftentimes sparser fuels. a slope is facing. North aspects are the most shaded, resulting in heavier fuels and higher fuel moistures. you are skiing, ask yourself, "which aspect might have sun-softened A clinometer measures the angle of the slope, elevation, or inclination of an object through sighting Good Visibility Because: 1.
