Effect of Small-Scale Wildfires on the Air Parameters near the Burning Centers

The results of seminatural experiments on the study steppe and field wildfires characteristic forest-steppe zones Western Siberia are presented. Using infrared (IR) thermography methods, main thermal characteristics fire front derived, flame turbulence scale is estimated, changes in structure function air refractive index analyzed vicinity a fire. effect model change meteorological parameters (wind velocity components, relative humidity, temperature) ascertained. Large-scale observed fire, which absent laboratory conditions. predominance large-scale turbulization atmosphere combustion center. Strong heat release zone increase vertical component wind produce fluctuations index, an indicator atmospheric turbulization. This creates prerequisites for formation proper during large fires. Variations gas aerosol compositions measured experimental site.
