“…Atmosphere 2020, 11 Several studies were devoted to the Krasnoyarsk's air problems [22,23], and some of them pointed out the disadvantages of the applied methodological approaches based on the GLAPM Several studies were devoted to the Krasnoyarsk's air problems [22,23], and some of them pointed out the disadvantages of the applied methodological approaches based on the GLAPM [24]. The problem of the Yenisei River, which is ice-free during the winter seasons and impacts on the wind flows, was also highlighted using the CFD modeling in [25].…”

Computational modeling allows studying the air quality problems in depth and provides the best solution reducing the population risks. This research demonstrates the Graz Lagrangian model effectiveness for assessing emission sources contributions to the air pollution: particles tracking and accumulation estimate. The article describes model setting up parameters and datasets preparation for the analysis. The experiment simulated the dispersion from the main groups of emission sources for real weather conditions during 96 h of December 2018, when significant excess of NO2, CO, SO2, PM10, and benzo(a)pyrene concentrations were observed in the Krasnoyarsk surface atmospheric layer. The computational domain was a parallelepiped of 40 × 30 × 2.5 km, which was located deep inside the Eurasian continent on a heterogeneous landscape exaggerated by high-rise buildings, with various pollutions sources and the ice-free Yenisei River. The results demonstrated an excellent applicability of the Lagrange model for hourly tracking of particle trajectories, taking into account the urban landscape. For values <1 MPC (maximum permissible concentration) of peak pollutants concentrations, the coincidences were 93 cases, and for values < 0.1 shares of MPC, there were 36 cases out of the total number of 97. The same was found for the average daily concentration for values <1 MPC—31, and for values <0.1 MPC—5 matches out of 44. Wind speeds COR—65.3%, wind directions COR—68.6%. The Graz Lagrangian model showed the ability to simulate air quality problems in the Krasnoyarsk greater area conditions.

The paper presents the results of a numerical forecast of the pedestrian comfort level in the territory of urban development. The research uses the microscale numerical model of the atmosphere in the urban environment, into which the equations of temperature and seasonal indices are integrated. These equations are used to simulate and analyse pedestrian comfort conditions. The paper presents the results of the proposed model approbation in the real environment of the residential neighbourhoods of Krasnoyarsk city. External conditions, typical for summer and winter seasons, were simulated. The results produced are presented as distribution fields of the considered indices. During the analysis, comfortable/discomfort areas for humans staying in the environment of studied urban development were revealed.

The article considers the influence of the relief, river, and urban development on the formation of vortex structures in the atmosphere and the spread of pollutants in the city of Krasnoyarsk in winter. The weak influence of urban development on the appearance of large vortex structures over the river is shown. However, in the ground layer, it significantly changes the flow pattern and determines the character of the distribution of pollutants.
