Abstract: The inventive device comprises telecommunications transceiver interacting with a network for data exchange and a user interface interacting with the telecommunications transceiver for displaying information extracted from received data, wherein telecommunications transceiver is arranged for receiving meteorological data from which a display for the user interface is extracted. Telecommunications transceiver is connected for spontaneously interacting with a station for defining a geographic area and for accessing, in a substantially uniform manner, to a data set containing forecast pluvial/duration pairs which are valid for the geographic area for consecutive periods, the data set being dated by a time marker. The user interface is provided with a range of ordinate display segments, each of which is provided with several display states.

Abstract: The inventive device comprises telecommunications means (18, 19) interacting with a network for data exchange and a user interface (2, 3) interacting with said telecommunications means for displaying information extracted from received data, wherein telecommunications means is arranged for receiving meteorological data from which a display for the user interface is extracted. Telecommunications means (18, 19) is connected for spontaneously interacting with a station (20) for defining a geographic area and for accessing, in a substentially uniform manner (21), to a data set containing forecast pluvial/duration pairs which are valid for said geographic area for consecutive periods, said data set being dated by a time marker. The user interface (2) is provided with a range of ordinate display segments (5A, 5E) each of which is provided with several display states.

Abstract: Automatic rain gauges (P00-P0n) are employed within the area of terrain (ZT). A meteorological radar (R1) provides, with a given radar periodicity, a radar image representing rain-bearing cells of concern to the area of terrain. By analyzing the succession of radar images, the main rain-bearing cells are tracked dynamically by their shape and motion. Then a radar rainfall measurement chart is compiled by accumulating, in each pixel of the area of terrain, the precipitations due, during a second chosen time interval, to these main rain-bearing cells, with interpolation of their shapes and positions. At least one sub-array (PA, PB) of four rain gauges separated from one another by about 2 to 4 kilometers and affected by at least one main rain-bearing cell is selected. Finally, the rainfall measurement chart is corrected at least partially as a function of the relation between the accumulated true rainfall data and those from the said chart at the locations of the rain gauges of the sub-array.
