Engineering Physics Annotation << Back Influence of duration of action of the electric category on probability of occurrence of forest fires N.V. Baranovskiy Duration of action of the electric discharge on forest fuel layer is the important parameter of ignition and occurrence of forest fire from thunder-storms. Influence of electric discharge duration on probability of occurrence of forest fire is investigated in present paper. The typical forest territory with prevalence of a pine is considered. Results of scenario calculations are submitted. Forest fire conditions corresponds Timiryazevo timber enterprise of Tomsk region. Keywords: Forest fire danger, ignition, electric discharge, probability. E-mail: firedanger@narod.ru
