Precipitation is a key element of the hydrological cycle. Its amount, intensity and duration as well as changes in totals, variability and extremes have a direct impact on the community regarding e.g. water availability, droughts, and flooding. Measuring, characterizing and modeling precipitation at small spatial and short temporal scales is still a big challenge. Especially in heterogeneous terrain such as urban areas with high vulnerabilities high-resolution measurements and modeling of precipitation are crucial in order to describe the hydrological response and improve water risk management.
This session provides a platform for contributions on high-resolution precipitation measurements and their applications in real-time as well as climate studies. Special focus is laid on documenting the benefit of high spatial and temporal resolutions dealing with high-resolution measurement platforms like satellite and radar networks or novel techniques like retrieving rainfall from microwave links. In addition, contributions on the development and improvement of gridded reference data sets based on in-situ precipitation measurements are welcome. Furthermore the enhancements resulting from the proper combination of different observational regimes shall be demonstrated and synthesized towards robust high-resolution regional and global data products.
A further focus is put on the seamless combination of high-resolution precipitation data, nowcasting products, and numerical quantitative precipitation forecasts (QPF) including hydrological applications.
This session also welcomes contributions on high-resolution hydrological modeling (1x1 km2 spacing or higher), especially regarding flash floods and urban flooding and aims to address contributions on the application of high-resolution precipitation data in hydrological impact studies.
In addressing these needs, one or more of the following topics shall be addressed:
• High-resolution precipitation observations from different platforms (gauges, radar, satellite, microwave link) and their combination
• Application of high-resolution remote sensing precipitation measurements in a climatological context
• Statistical analysis of extreme precipitation (events)
• New concepts of adaptation to climate change with respect to extreme precipitation in urban areas
• Vulnerability and resilience in urban areas
• Statistical description of sub-kilometer scale precipitation / downscaling methods
• Accuracy assessments and verification approaches for high-resolution precipitation products
• Contribution to the WCRP GC on ‘Understanding and Predicting Weather and Climate Extremes’ and on ‘Water Availability’.
• Seamless transition from gridded QPE to QPF from NWP models
• High-resolution hydrological modeling
• Urban hydrology
• Application of high-resolution precipitation data in hydrological models
• Experience from real-time applications
