Abstract: ： Comprehensive analysis and summary of the current city-level forecasting business and meteorological service work characteristics and existing problems. In the process of forecasting product production, the problems of different sources of reference materials, various distribution channels, changeable business platform, and delay of early warning information transmission are discussed. A solution based on C/B/S meteorological disaster warning decision support system is proposed. First, it analyzes and classifies the auxiliary decision data source and the concrete forecast business production, and formulate mixed mode that use the multi thread C/S data processing and the B/S data display. In the overall framework of the system, the Oracle database storage service, the WebGIS technology, leaflet plugin, the Mybatis framework of the background service are used. The article elaborates on the technical design schemes of the system and gives the specific design method under the mixed mode. The actual operation results show that the model greatly improves the real-time and flexibility of the system, and the efficiency of forecasting business services has also been improved.
