Evaluation of the QPF of convective flash flood rainfalls over the Czech territory in 2009
Result description
In this paper, quantitative precipitation forecasts are evaluated using several verification techniques and analysis of the results from these techniques. The forecasts were produced by two limited-area NWP models: the ALADIN-CZ model operated by the Czech Hydro-Meteorological Institute and the COSMO model operated by the German Weather Service. Each model was run using two horizontal resolutions over the domain covering the Czech Republic. The ALADIN-CZ model outputs were obtained using resolutions ofapproximately 9 km and 4.7 km, and the COSMO model outputs were obtained using resolutions of approximately 7 km and 2.8 km. A series of 3-h rainfalls was verified using traditional and spatial verification techniques, and the results from these analyseswere compared. The verification was performed using traditional verification scores based on a contingency table, spatial verification by the fractions skill score and the SAL technique. The FSS represents a fuzzy verification technique
