Abstract

Currently, the ongoing climate changes require the specification of meteorological parameters that cause the dispersion (accumulation) of impurities that come in the form of emissions from industrial enterprises and motor transport. Due to the reduction of the points and the frequency of the aerological sounding of the atmosphere it is not possible to use the information on the vertical distribution of temperature with the necessary discreteness. Experts began to develop criteria for assessing the potential accumulation of pollutants in atmospheric air on the basis of surface meteorological observations.

Using surface meteorological observations of the daily dimension of the Belgorod center for Hydrometeorology and environmental monitoring, meteorological conditions for dispersion of impurities in the Belgorod region were studied, intra-regional differences of these characteristics were established, and calculations of meteorological potential of self-purification of the atmosphere in the region were made. The proposed method for determining the meteorological potential of self-purification of the atmosphere is sufficiently informative and can replace the use of the calculated climatic characteristics of the potential for air pollution in the conditions of reduction of aerological sounding. The territorial distribution of the mentioned characteristics are the same. The self-purification factor makes it possible to evaluate the contribution of meteorological phenomena and their characteristics in the formation of air pollution.

Calculations have shown that the most unfavorable parameters are observed throughout the year in the North-East of the region, where there is a significant concentration of population and industrial facilities in the area of development of KMA, which requires additional measures to control the environmental situation from controlling environmental organizations. At the same time, considering seasonal frequency of work of the processing enterprises of agro industrial complex, it is necessary to give preference to placement of such organizations in the Central regions of area. The study of the meteorological potential of self-purification of the atmosphere makes it possible to give recommendations on the optimal variant of the placement of technogenic loads in the region.

Keywords
