How does topography affect fire behavior

WebTopographic factors that affect the start and spread of wildland fire are aspect, slope, shape of the area, elevation, and barriers. Aspect is the exposure of a slope to the sun. It usually determines the amount of heating the land gets from the sun. North of the equator the sun’s rays shine most directly upon the south and southwest slopes.
