Abstract

The results of a statistical analysis of the number of days with hail during the warm half-year 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).
1891-2021年第比利斯暖季冰雹日数统计分析
本文介绍了1891年至2021年第比利斯暖半年冰雹日数的统计分析结果。研究了冰雹日数的测量值以及3年、5年、7年、9年和11年冰雹日数的移动平均值的时间变率。发现所有指示的观测序列的时间过程都是负的,并且用线性回归方程来描述。与此同时,年与实测冰雹日数的线性相关程度以及冰雹日数的移动平均随着平均范围的增加而增加(分别从-0.22到-0.63)。
