Origins of “unusual” surface ozone behavior in April’2019
Abstract
The unusual behavior of surface ozone revealed in April’19 over some Belarusian cities has been analyzed. Here, the first and third decades of the month were featured by a high amplitude of the diurnal ozone course, yet, in the second decade, its sharp decrease was observed. Among possible reasons for this occurrence, one has treated changes in aerosol amount, varying meteorological conditions and levels of anthropogenic air pollution in cities. The results of the analysis indicate that the main cause of the strange behavior of surface ozone was a decrease in the vertical stability of the atmosphere leading to a more intense dispersion of pollutants and, thus, to a decrease in their concentrations in surface air. This contributed to the inhibition of the processes of surface ozone generation and destruction.
