| Abstract: | The present situation of geological hazard forecasting and warning research and system development is introduced, and the design ideas, system components, main functions and features of the meteorological forecasting and warning system of geological hazards for the mountainous areas of Hebei Province is expounded. The design of the system is reasonable, considering the such information as the geological hazard regionalization, GIS data, meteorological observation (including intensive regional precipitation observation, Doppler radar products, cloud satellite images, lightning position, etc), numerical forecasting products of precipitation, etc. Adopting the mathematical statistical, synoptic dynamic method, and advanced computer technology, it is able to create forecasting and warning products conveniently. The operational application in the flood season of 2007 proved that this forecasting and warning system of geological hazards performed well with considerable accuracy and less no hitting and false hitting rates. |
