Popis: Statement of the problem. Due to a sharp lack of free areas particularly in large cities, there is a growth in the number of high rises. There is an overall principle of construction employing compaction of existing residential areas, particularly in central densely populated urban areas. As a result, there are what is called street canyons of giant cities. They accumulate thermal and contaminant pollutions (toxic vapors, aerosols, etc.), which eventually lead to a significant environmental degradation. Mathematical modeling allows the dynamics of changes in the air quality in a layer adjacent to the ground to be predicted in street canyons and to be instantly controlled. Results. The corrected image of the mathematical model of flowing of air flows in urban street canyons was proposed to enable a simpler numerical solution while predicting the dynamics of change in the air quality in a ground layer. Conclusions. Calculations using the suggested equations of the mathematical model would allow quicker prediction with no use of complex super-power software.
