Influence of military actions on the process of the formation of precipitation

Abstract

This work concerns the study of the influence of military actions on the development of global ecological processes, in particular, the fall of acid rain from individual single explosions. A mathematical model is proposed, which takes into account the emission of pollutants into the subcloud washout zone and the kinetics of the condensation process. The concentration of combustion products in the atmosphere at the level of three to five diameters of the explosion area (the area of the formed explosion funnel) is found using the theory of a convective jet from a warm source to the environment. At the same time, we determined the speed of warm air that rises above the area of the explosion, the average temperature in the transition section of the convective jet, and the flow rate of polluted air in the upper part of the jet. The paper presents a system of dimensionless non-stationary differential equations for a high unshaded source, which can be used to determine the dispersion of the main acid-forming substances in the Boussinesq approximation with the variables "eddy velocity – current function – temperature – concentration" with appropriate initial and boundary conditions. Sulfuric anhydride was considered as an example of the main acid-forming substances and the most dangerous and toxic compounds of explosion products. The proposed mathematical model can be used to forecast the possible fall of acid rain on the territories adjacent to single explosions, thereby making a forecast of changes in environmental risk as a result of military operations for the environment and the population. and will make it possible to determine the zones of influence and dispersion from the place of the explosion.
