Flash floods in small to meso-scale catchments and intense precipitation over cities from severe local storms pose increasing threats to our society. For the timely prediction of such events, the value of high-resolution and high-quality quantitative precipitation estimation and corresponding forecasts cannot be overrated.

Seamless predictions harmonizing nowcasting and NWP across forecast lead times from minutes to days would greatly help to improve the value and efficiency of warnings. The DFG research group on Near-Realtime Quantitative Precipitation Estimation and Prediction (RealPEP) addresses recent ideas and achievements along the process chain from quantitative precipitation estimation (QPE), observation-based nowcasting (QPN), combination of nowcasting with NWP and flash-flood prediction (FFP). Area-covering and high-resolution polarimetric weather radar observations currently provide core information for QPE/QPN like precipitation intensity, hydrometeor types, and wind gusts augmented with satellite and lightning observations.

With the perspective to enable/improve seamless predictions of surface precipitation and flash floods from the time of observation to days ahead, RealPEP organized a conference on advances in quantitative high-resolution precipitation retrieval including promising sensor synergies, advances in nowcasting including life cycle information from radar and satellite observations, advances in NWP data assimilation for short-term forecasts, concepts for merging observation-based QPN with NWP, and concepts to transfer the uncertain precipitation estimates over the forecast range into river runoff and flash-flood predictions.
