THE EFFECT OF SEVERE SMOG POLLUTION ON TURBULENCE

Abstract This study examines the complex interaction between anthropogenic air pollution and atmospheric turbulence. Particular attention is given to the critical role of turbulence in dispersing harmful substances within the atmospheric boundary layer. It is shown that pollutants such as soot not only deteriorate air quality but also suppress turbulent transport, thereby creating a positive feedback loop. This process leads to atmospheric stabilization and the accumulation of hazardous concentrations of fine particulate matter with diameters smaller than 2.5 µm, ultimately forming persistent smog. Conversely, reducing soot emissions can enhance turbulence and improve ventilation. The study summarizes field observations and modeling results that demonstrate the influence of the turbulent barrier effect and meteorological factors on pollutant transport. The findings provide a foundation for developing effective strategies to improve air quality and protect public health.
