The illustration covers the period from 2001 to 2022 using stacked columns to show the annual number of heavy-rain events in Germany, differentiated by eleven duration levels – 1 hour, 2 hours, 3 hours, 4 hours, 6 hours, 9 hours, 12 hours, 18 hours, 24 hours, 48 hours and 72 hours. In this context, a heavy-rain event is an amount of precipitation which equates to DWD warning level 3 or higher. In the course of the period examined, the height of the columns increased, albeit subject to slight fluctuations; in other words, the number of heavy-rain events shows a rising tendency. The events of 1 hour duration and 2 hours duration respectively account for the greatest proportion of all events. Typically, they account for approximately 50 per cent of all heavy-rain events. Individual years with a particularly high number of heavy-rain events stand out from the time series. In the years of 2002, 2006, 2014 and 2021 more than 1,500 heavy-rain events occurred. In 2018 the value amounted to more than 2,000.
