Statistical analysis of the number of days with hail during the warm season in Tbilisi in 1891-2021.
2023
The results of a statistical analysis of the number of days with hail during the warm season in Tbilisi from 1891 to 2021 are presented. The temporal variability of the measured values of the number of days with hail, as well as the moving averages of the number of hail days for 3, 5, 7, 9, and 11 years, has been studied. It is found that the time course of all the indicated series of observations is negative and is described by the linear regression equation. At the same time, the level of linear correlation between years and the measured number of days with hail, as well as moving averages of the number of hail days, increases as the averaging range increases up to 11 years (from -0.22 to -0.63, respectively).
