Web6. General Winds. 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. WebFeb 15, 2024 · In this study, we use landscape fire simulations to examine the influence of topography and fuel load on potential fire behavior. Analysis of severity patterns following actual wildfires would be confounded by correlations between terrain, vegetation, and fuels, and the stochastic effects of weather.
