Abstract
The performances of two rainfall-estimation methods based upon the infrared channels of geostationary satellites are examined for very-short-range weather forecasting. A flood-hazard monitoring application in the Arno River Basin in Central Italy in November 1987 is presented. Results demonstrate that the rain-estimation techniques applied in the nowcasting environment are a powerful aid to the forecaster. Evidence is also provided that rain estimates must be correctly interpreted in terms of the structure of precipitation systems to avoid the considerable errors that can stem from routine, purely numerical applications. -AuthorsFile in questo prodotto:
