Abstract

The study analyzed 8295 daily rainfalls recorded in Wrocław from 1960 to 2017. The frequency of daily precipitation in a year was determined in nine categories: from very weak (less than 1.0 mm) to disastrous (over 100 mm). In addition, the precipitation trends were determined by linear regression and the Mann-Kendall test. Analysis of the variability of the number of days with precipitation of particular categories showed a statistically significant downward trend for moderately strong precipitation (10.1-20.0 mm). In case of other categories of precipitation, the tests did not show statistically significant changes.
