Abstract
In their everyday operational work, forecasting offices issue weather warnings at a high update frequency and with very precise geographical specifications. In order to meet these requirements, the analysis system cannot be restricted to stations but needs to be spatially quasi-continuous. In regional nowcasting, an integrated semi-quantitative precipitation field is constructed as a combination of conventional surface observations and radar data, while in areas with no rain gauge data and low radar reliability satellite data are exploited. For this purpose, satellite/NWCSAF precipitation products are validated. An applicable algorithm which
would provide semi-quantitative information about rainfall is proposed. The work is being done within the framework of the Central European Nowcasting Project CONEX II.
