Precipitation
| Precipitation is the deposition of water on the earth surface, in the form of rain, snow, ice or hail (see Type ). All precipitation amounts (see Measurement ) are expressed in millimeters (mm) of liquid water equivalent for the preceeding time interval. One millimeter of rain corresponds to 1 liter per square meter of water on the surface, or approximately 10 millimeters of snow. We present our best high resolution precipitation forecast in the p☼int meteograms, Picto-cast, rainSP☼T and on the meteoMaps. Other parameters include precipitation probability is always calculated from an ensemble of 20 model ensemble de 20 runs. The proability is the frequency with which precipitation occurs in these 20 different forecast calculations. Further details are provided under Interpretation. Special presentations can be made on request. Other presentations and scales can be supplied on request. |
