Seasons of Drought in Slovakia During the Period from 1957 to 2016

The aim of the paper was to describe the occurrence of dry seasons in Slovakia. Dry seasons in the period from 1957 to 2016 were determined according to the monthly Palmer Drought Severity Index (PDSI). For this purpose, ten sites based on limit climatic parameters were chosen – Bratislava, Piešťany, Hurbanovo, Čadca, Sliač, Boľkovce, Poprad, Košice, Milhostov, and Kamenica nad Cirochou. The results showed the alternation of dry and wet episodes and the variability of weather not only over time, but also over space. The analysis of linear trends showed that the arid trend was identified on most sites (9 localities).
