About meteorological information

HHFS receives observed meteorological data from Hungarian and other European stations as well as reports describing the actual meteorological situation. Based on this information maps are produced of the most important meteorological parameters concerning hydrology. Irregularly situated observations are made appropriate for map representation through HHFS' own developed downscaling and parameter estimation methods which are necessary to produce high level maps. Legends were defined using threshold values relevant in hydrology, therefore they may significantly differ from the conventional meteorological scaling and colour usage.
