This study introduces a nonlinear mathematical model and a numerical algorithm for simulating the emission and transport of aerosol and dust particles generated by wind erosion of soil in complex orographic terrain. The model accounts for meteorological parameters, physicochemical properties of particles, soil moisture, and surface roughness. The numerical implementation employs a finite-difference method on a structured grid with the integration of the Navier-Stokes equations and the pollutant transport equation. A series of numerical experiments was conducted to investigate the influence of wind, soil moisture, and other environmental factors on the intensity of erosion processes and atmospheric pollution. The results demonstrate the strong sensitivity of particle emission to near-surface meteorological conditions and landscape geometry, underscoring the importance of a comprehensive approach to forecasting environmental risks in arid and semi-arid regions.
