Forest fires occur for natural and anthropogenic reasons. In the vicinity of settlements, forest fires occur mainly as a result of human activity. The occurrence of a forest fire is characterized by the presence of a person in a forested area (anthropogenic load), the presence of ignition sources and the process of forest fuel ignition. It is important to understand how the anthropogenic load is distributed around the locality and to simulate it using computer technology. The purpose of the work is a numerical stu...

Forest fires damage biogeocenoses. Forest fires affect trees, vegetation and soils. This influence can be both positive and negative. The thermal effect of a forest fire on the soil layer is important. It is necessary to develop mathematical models for understanding the processes of thermal effects of a forest fire on the surface soil layer. Earlier, a simple mathematical model was developed which takes into account the given characteristics of a forest fire and heat transfer in the soil layer by conduction. The p...

Atmospheric-soil measuring complex (ASMC) contains ten-meter mast with five temperature and humidity sensors in the radiation protection at altitudes of 1, 2, 4, 6 and 10 m. In addition, a wind speed, wind direction and total solar radiation sensors are installed on the mast. Also a solar battery and an antenna for a cellular modem are installed on the mast. Near the mast there is a snow cover height sensor and a liquid precipitation sensor on a two-meter tripod. The soil part of the stationary variant for monitor...

In this paper stochastic model is proposed to estimate the probability of forest fire from anthropogenic load. A point source of anthropogenic load is considered. For example, a rural settlement, a camp, an industrial site, which are located in controlled forest-covered areas. Mathematically, the following model can be formulated. Let?s consider circle with radius in the some set. Then the cumulative distribution function (c.d.f.) of ignition near the neighborhood of the point X0 can be defined. Obvious that all p...
