Abstract : Charts were prepared of the mean number of days with near or distant thunderstorms per year and for the four months of the warm period - May to August during which thunderstorm activity is most pronounced. In addition, for the characteristics of the annual course and duration of the thunderstorm period, diagrams of the mean and maximum monthly number of thunderstorms were prepared for a number of stations. The charts were compiled chiefly according to the number of thunderstorm days in the data of the Climatic Handbooks of the USSR (Klimaticheskie Spravochniki SSSR). In the preparation of the maps of the number of days with thunderstorms, use was made of data from about 21000 meteorological stations with varying lengths of observational records within the period 1891-1948. As a rule, data from stations having at least 10 to 15 years of observation were used. In regions of inadequate thunderstorm data coverage, especially in mountainous regions, station records with observational periods of less than 10 years were employed, in order to approximate the order of magnitude of the number of thunderstorm days.
