M-Components Mathematical Modeling for Coniferous Tree Ignition

Abstract

Based on the one-dimensional three-layer physical and mathematical model of ignition of a coniferous tree (pine), the influence of the m-components of the cloud-to-ground lightning discharge and the appropriateness of their consideration in technical systems for monitoring the forest fire danger are evaluated. The problem is solved in a cylindrical coordinate system. Typical cloud-to-ground lightning discharges are considered. An assessment of the influence of m-components was carried out for a typical range of changes in their characteristics.
