Brief Communication: On the extremeness of the July 2021 precipitation event in western Germany

Katharina Lengfeld, Paul Voit, Frank Kaspar, and Maik Heistermann

Abstract. The weather extremity index (WEI) and the cross-scale WEI (xWEI) are useful parameters for determining the extremeness of precipitation events. Both rely on the estimation of return periods and, therefore, the estimation of GEV parameters. When including the year 2021 in this estimation, the devastating event in July 2021 drops from first to fourth place regarding the WEI compared to all events between 2001 and 2020, but remains the most extreme regarding the xWEI. This emphasizes that it was extreme across multiple spatial and temporal scales, and the importance of considering different scales to determine the extremeness of rainfall events.
