The primary objective of the study is to follow-up the quantitative changes in precipitation between 1901 and 2011 in the city of Debrecen. This dataset of 111-year interval allows us to reveal the quantity and distribution of precipitation changes and modification as part of today's global climate change. The amount of annual precipitation in Debrecen showed a decreasing trend during the examined period but not significantly (∼30 mm decrease in 100 years). It can be seen from each seasons that in winter and spring there are approximately no changes in the trend, while in summer an increase and in autumn about a same level decrease can be identified. Thereafter we determined the 80% design storm, which is widely used in practice, based on the data measured in the last 30 years.
