Zusammenfassung |
In the framework of the RAPHAEL EU project, a series of past heavy precipitation
events has been simulated with different meteorological models. Rainfall hindcasts and
forecasts have been produced by four models in use at various meteorological services or
research centres of Italy, Canada, France and Switzerland. The paper is focused on the
comparison of the computed precipitation fields with the available surface observations.
The comparison is carried out for three meteorological situations which lead to severe
flashflood over the Toce-Ticino catchment in Italy (6599 km2) or the Ammer
catchment (709 km2) in Germany. The results show that all four models reproduced
the occurrence of these heavy precipitation events. The accuracy of the computed
precipitation appears to be more case-dependent than model-dependent. The sensitivity of
the computed rainfall to the boundary conditions (hindcast v. forecast) was found to be
rather weak, indicating that a flood forecasting system based upon a numerical
meteo-hydrological simulation could be feasible in an operational context.
