Аннотация:Acoustic remote sensing, measurements of solar radiation and monitoring of air pollution are carried out continuously at the Department of Meteorology and Climatology of the Moscow State University. On base of these data a dynamic of ozone in morning and its connections with an inversion existence and the ultraviolet radiation have been studied both for separate days, and in average for 27 days of anticyclone conditions. Usually in these conditions the ultraviolet radiation grows in morning gradually. However, a rate of increasing of the surface ozone sharply changes. Firstly it grows only a bit, but after lift and vanishing of an elevated inversion (accordingly to the sodar data) this growth sharply accelerates. Thus, temperature inversions significantly influence the ozone dynamic because they prevent intense vertical mixing in low atmosphere.
One more observed effect is sharp increase of dispersion of the surface ozone concentration from one minute to another just after destruction of an inversion and development of the thermal convection.
