The climatic features of the atmospheric boundary layer above the south of western Siberia

Abstract

Troposphere and, in particular, the atmospheric boundary layer play a considerable role in propagation and transformation of optical radiation. Therefore, data on vertical statistical structure of meteorological fields in the boundary layer are necessary for solution of various applied problems of atmospheric optics. In the work, climatic features of the atmospheric boundary layer above the south of Western Siberia are considered. The research was conducted for winter and summer using the date of four-years (2002.2005 years) observations of 4 aerologic stations (Ekaterinburg, Omsk, Novosibirsk and Krasnoyarsk). The vertical structures of average values and mean square deviations of temperature, humidity and wind for 10 high-altitude levels (up to 1600 M), as well as the corresponding correlation matrixes and results of their expansion on empirical orthogonal functions were used for detailed studying of climatic features of atmospheric boundary layer. The obtained results are presented.`
