Changes repetition of thunderstorms in summer months above a city Kiev can be described with high exactness by the method of linear multiple regression. The identified models possess robastnost to the temporal changes in the future on 22 years and that is why can be used for prognostication of further dynamics of this process to 1930 year.

The features of the distribution of temporal variability of the trends of thunderstorm activity in May - Au-gust on various regions of Ukraine, which appeared during the period of the modern global warming. As a quan-titative measure of trends, we used the slope of the linear trend of the time series. Found that during this period over most regions of Ukraine thunderstorm activity has increased. This corresponds to the notions of the possible consequences of global warming, which leads to an increase in the total content of water vapor in the Earth's atmosphere and changes in cyclone activity over the regions of Ukraine.
