Background and Goals
Extreme weather events such as heavy precipitation represent an enormous challenge for those responsible in disaster control as well as in urban and spatial planning. The Germany-wide evaluations of the radar climatology project form a new meteorological basis for the spatial and temporal resolution of extreme precipitation events in a much more precise resolution (1x1 km²) as previously possible. For the period from 2001 onwards, it is not only possible to identify where and when a heavy rain event took place, but also, in perspective, with a sufficiently long series of data, whether and, if so, in which regions of Germany there is a trend towards more extreme precipitation events.
The statistical evaluation of heavy rain events and the analysis of individual events using indices as well as the integration of further meteorological and non-meteorological data are intended to answer the following questions:
- How can the connection between extreme precipitation events and operational events be described both qualitatively and quantitatively?
- Which city districts and settlement types have been particularly affected by heavy rain in the years since 2001?
- Which meteorological and non-meteorological active components determine the spatially different effects of a heavy rain event?
- Which measures can support risk prevention against heavy rain in civil protection and urban development?
Steps in the process of adaptation to climate change
Step 2b: Identify and assess risks - Vulnerability, risks and chances
The statistical evaluation of heavy rain events and the analysis of further data are used to determine which quarters and settlement types are particularly affected by heavy rain and why.
Step 3: Develop and compare measures
With better knowledge of the spatially different effects of heavy rain, targeted measures for heavy rain precautions in civil protection and urban development can be developed.
