Stepanenko S. The dynamics of turbulence-circulation and diffusion processes in low atmospheric layer over Ukraine

Мathematical simulation of internal structure of an atmospheric boundary layer (АBL) and both processes of distribution and dispersion of polluting substances in the LAL on the basis of the standard meteorological information. An atmospheric turbulence-circulating and diffusion model for the diagnosis and forecast of the LAL dynamics and its ecological conditions with regard to the main physical generating mechanisms of time-spatial distribution of meteorological values, features of turbulent exchange and transport of pollutants above Ukraine is developed. The techniques of parametrization of orography effects in the task of restoring of the internal ABL structure and LAL ecological conditions, a classification of conditions of the internal ABL structure generation, regional transport and diffusion of pollutants are suggested. The results put into use with operating prognostic divisions of the Ukrainian and Russia Hydrometeorological Services.
