An Analysis of Intense Rainfalls in Cracow Area

The study involves an analysis of intense rainfall events determined based on data from 21 precipitation stations located in the area of Cracow. The data was extracted from rainfall sequences from years 2013–2017 at the Municipal Water and Sewage Company (MPWiK [Miejskie Przedsiebiorstwo Wodociągow i Kanalizacji]) in Cracow. The analysis was carried out using the sequences of highest intensity from the summer months, i.e. VI–IX. Applying the Chomicz scale, identified were the types of rainfalls which occurred in Cracow in the observed time. It has been shown that the two types of intense rainfall, rainstorms and heavy rainfalls, were prevalent in the selected years of observation whereas regular types were infrequent. Analysed were rainfalls which occurred on the same day of the given observation year at all of the precipitation stations of the MPWiK in Cracow.
