Repeatability and dynamics of probability of various type of droughts, and also estimation of their intensity on hydrothermal factor for the 120-year-old period (1891–2010гг is shown.). The agrometeorological characteristic of the most severe droughts is given. Decrease in productivity of grain crops and total gathering of grain in the Saratov area in years with various types of droughts is resulted

In the article the comparative analysis of repeatability of droughts of different intensity is presented in the separate interval of vegetation period on the natural zones of the Saratov area in 1951–1980 years and after 1981–2015 years. Centers of origin of droughts and their repetition on the area of coverage of the territory are shown.
