Abstract:

Vertical motions observed in synoptic vortex (upward – in cyclone and downward – in anticyclone) have a primary influence on not only the formation and growth of clouds, but also spread of admixtures of both natural and anthropogenic origin, as well as levels of air pollution near the Earth's surface. The influence of such parameters as geostrophic and surface wind, surface roughness, thermodynamic stability of the ground layer of the atmosphere, and the horizontal size of vortex on the vertical velocity was estimated using equations of the similarity theory. The results are presented as tables, which allow calculation of the vertical velocity at any level of the boundary layer using the data of synoptic maps. A good agreement of results (in the boundary layer) on vertical velocity calculation within the framework of the similarity theory and using the equation approximating the vertical velocity within the entire troposphere suggests that the latter equation can be used in modeling of the atmospheric processes and phenomena.
