A detailed analysis is made of a prefecturelevel monitoring system of meteorological emergency service, taking the Liaocheng (Shandong Province) mobile weather station as an example, in three aspects: equipment selecting and matching, communication networking and video conferences, and construction of forecasting service platform. Meanwhile the application of the system to the fast acquisition of emergent meteorological disaster information and the effectiveness evaluation of airborne water resources utilization is discussed, so to provide useful references for improving prefecturelevel meteorological emergency service.
