Definition of the Characteristics of an Urban Hydrological Radar: Interest of the Vertically Integrated Liquid Water Content

Résumé

The objective of this communication is to evaluate the usefulness of volumetric radar data (VIL) for short-term rainfall forecasting purposes. A conceptual rainfall prediction model with real-time assimilation of surface rainfall and VIL only is presented. During the developing stage, the model is initialised and tested with simulated data from a mesoscale meteorological model which are used as quasi-ideal reference data. Results from the conceptual model predictions are compared with the reference data and with results from a simple advection model. Results show that the conceptual model produces qualitatively and quantitatively better results than the advection model for forecast lead-times that are within the range of the response times of the catchments.
