Abstract

The paper presents a three-dimensional numerical model developed by the authors, which describes the change over time of thermodynamic and microphysical characteristics of the atmosphere in the computational domain, the distribution of impurities on a local scale (up to 50 km) from various sources, taking into account the actual or forecast fields of meteorological parameters. The model differs in that it takes into account the microphysical processes of interaction of impurities with the cloud environment. To obtain three-dimensional prognostic fields of meteorological parameters at the initial time (when initializing the model), a combination of data from the global forecasting system GFS and data from remote observations using Doppler meteorological radars is used. Validation of the model on various test data is carried out. Numerical experiments were performed using orography and the actual distribution of wind in the atmosphere. The use of data of instrumental measurements and forecast system allows obtaining a detailed analysis of the environmental situation in the study area.
