TO THE QUESTION OF EMERGENCE OF FOREST FIRES THROUGH SELF-IGNITION OF FOREST UNDERLAY
It is noted that forest fires cause huge economic damage to the state, pollute the environment and adversely affect the health of the population. The paper analyzes the causes and circumstances of fires in the forests. The main attention is paid to the conditions of the emergence of self-ignition of the forest underlay in coniferous forests, which can occur under certain weather conditions. The appropriate thermophysical calculations have been done. There also have been examined the specific examples of self-ignition of the forest underlay in coniferous forests near Voronezh in the beginning of winter and the possible causes of self-ignition of coniferous underlay in the forests of Siberia in the summer period.
