The maximum average number of days with hail is observed in Manglisi (4.6), the minimum - in Sadakhlo (0.2). The maximum total area of agricultural crops damaged by hail was noted in Asureti (8.15 km²), the minimum in Tbisi (0.2 km²). The maximum area of agricultural crops damaged by hail by 100% was noted in Sadakhlo (6.18 km²), the minimum - in Tbisi (0.07 km²). In the whole region, for one incident with hail, the total area of damage to agricultural crops was 1.64 km², and for 100% - 0.95 km². The results of this work will be used to construct a visual map of the distribution of hail cases and hail damage of agricultural on the territory of Kvemo Kartli.
