(author), van Heeringen, Klaas Jan (author), Velasco-Forero, Carlos (author), Nerini, Daniele (author), Van Ginderachter, Michiel (author), Weerts, Albrecht H. (author)Flash flood early warning requires accurate rainfall forecasts with a high spatial and temporal resolution. As the first few hours ahead are already not sufficiently well captured by the rainfall forecasts of numerical weather prediction (NWP) models, radar rainfall nowcasting can provide an alternative. Because this observation-based method...journal article 2023

Imhoff, R. O. (author), Brauer, C. C. (author), van Heeringen, K. J. (author), Uijlenhoet, R. (author), Weerts, A. H. (author)To assess the potential of radar rainfall nowcasting for early warning, nowcasts for 659 events were used to construct discharge forecasts for 12 Dutch catchments. Four open-source nowcasting algorithms were tested: Rainymotion Sparse (RM-S), Rainymotion DenseRotation (RM-DR), Pysteps deterministic (PS-D), and probabilistic (PS-P) with 20...journal article 2022
