Abstract:

Results of complex experiments on thermal structure of the boundary layer over Moscow performed by direct and remote methods are presented. Temperature profiles have been measured by sensors located on Ostankino TV tower and by low–level radar sondes located in the Central Aerological Observatory (Dolgoprudnyi town). Remote sensing has been carried out in Moscow and in Zvenigorod using three acoustic locators (sodars). Stratification type has been determined from facsimile recordings of sodar echos. Comparison of the data obtained simultaneously by different methods has been made; inhomogeneity of the temperature stratification of the lower atmosphere layer over Moscow has been estimated; periodical repetition of its main types during summer has been investigated. Comparison of the data obtained by simultaneous acoustic sounding at three points demonstrates influence of the big city on thermal structure of the atmospheric boundary layer.
