This paper investigates the spread of pollutants in a residential area of Almaty city. To implement the problem, special attention is paid to taking into account real weather conditions with different directions and wind speeds, which depend on time. The obtained results show that the direction of the wind over time affects the distribution of temperature and relative humidity of the air on the dissipation of concentration. Two types of NO and NO2 pollutants were considered from both sides of the road. Also,air humidity and wind direction over time presence significantly change the distribution of concentrations and temperatures in a residential area, based on a real case for the city of Almaty. As a result, the simulations were given estimates of the distribution of pollutants in a residential area, taking into account real weather conditions, and an effective way to reduce pollution levels is not the dense building of city streets.
