Proceedings of SPIE Vol. 12341 : 28th International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics, 2022, Tomsk, Russia. P. 123416A-1-123416A-9Abstract: Numerical simulation of the lift and spread of contaminants formation is carried out. Calculations show that the interaction of the impurity cloud with the surrounding air is insignificant for static atmospheric conditions, and dilution occurs at higher altitudes. An increase in the atmospheric turbulence intensity followed by stronger mixing, while an increase in the cloud size and a greater dilution of the contaminant is observed. The performed calculations made it possible to determine the level of pollution for various meteorological conditions and sources of pollution.
