According to the current situation of county level meteorological service development, the production principles of television weather forecast program are discussed, and the equipment layout and signal flow diagram of the weather video production system are designed. Also the principles and configuration of the related core equipment, the production processes and working procedures of the county level video weather forecast programs are described. Combined with the actual situation of county level meteorological television production, a prefectural level meteorological video production system is designed, which includes such parts as moderator’s commentary collection, site recording and dubbing, program data compression, and transmission. The system achieves the centralized production and rapid transmission of county level television weather forecast programs, and improves working efficiency effectively.
