This paper is devoted to the research of speciotemporal variable conditions for self-cleaning of surface atmosphere in the territory of the Urals. For this purpose the method put forward by T.S.Selegej and co-authors has been applied. The researchers have used the data taken from handbooks on the USSR climate issued in 1966 and 1968 to calculate the climatic potential of atmosphere dispersion. The scientists have calculated the climatic potential values of atmosphere dispersion in the Urals on a monthly and annual basis. The calculations have been made at eleven meteorological stations located in Perm, Sverdlovsk, Chelyabinsk and Kurgan regions. Unfortunately, the handbooks on the USSR climate contain no data required for calculations of climatic potential of atmosphere dispersion on territory of Bashkiria. The annual values of climatic potential of atmosphere dispersion vary from 0.47 in Kudymkar to 0.97 in Krasnoufisk. Thus, the annual values of climatic potential of atmosphere dispersion allow the researchers to determine quite favorable conditions for the dispersion of impurities in the atmosphere at ten meteorological stations in the region under study, and extremely favorable conditions for such dispersion at one meteorological station. The monthly values of climatic atmosphere dispersion potential in Sverdlovsk region change from 0.37 (meteorological station in Nizhnij Tagil) to 1.43 (meteorological station in Krasnoufisk), in Perm region - from 0.28 (meteorological station in Kudymkar) to 1.15 (meteorological station in Biser), in Chelyabinsk region - from 0.37 (meteorological station in Zlatoust) to 1.18 (meteorological station in Bredy), in Kurgan region - from 0.37 (meteorological station in Kurgan-Voronovka) to 1.03 (meteorological station in Shatrovo). Therefore, in annual self-cleaning conditions of surface atmosphere in the Urals vary from the extremely favorable to adverse. The executed researches present certain practical importance, as the obtained data on the spaciotemporal variability of climatic atmosphere dispersion potential in the territory of the Urals should been taken into account when planning and realizing particular air quality management measures in the region. Under adverse and extremely adverse conditions for atmosphere self-cleaning it is necessary to reduce the emissions of polluting substances from stationary sources, and also to limit the amount of transport in city streets. Under favorable and extremely favorable conditions for atmosphere dispersion it is possible to increase the emissions from stationary sources to certain limits and to increase the amount of city transport.
