Abstract: A new generation domestic meteorological telecommunication system was important promotion after “9210 project”. The unified management platform of the national and provincial meteorological departments was established, including data transmission, processing and system monitoring function. According to the national meteorological wide band development schedule, the current meteorological telecommunication system will be replaced by a new generation of domestic meteorological telecommunication system. At present, the new generation domestic meteorological telecommunication system and the current operational system were running simultaneously, which was the needs of not only the new system test but also the localization configuration and flow management. The operational flow of the new generation meteorological telecommunication system was set up and run in the operation work in Liaoning province based on the classification flow, which operates synchronously with the current system. Radar products and its basic data were transferred to the new generation domestic meteorological telecommunication system by PUP software, so were automatic weather station (AWS) data and wind energy data by the software of center station, while others were transferred by 9210 transmission server and radar transmission server. The results show that all meteorological information can be transmitted to the National Meteorological Information Center by the new generation communication system and it does not affect the current business. This meets the needs of testing the new generation communication system and localizing application. Flow design of this system is reasonable, and it can meet the demand of the meteorological information transmission quality check. At last, the current telecommunication system transportation flow, the aim and rule as well as scheme of design of the new system flow, and its operational effect are introduced.
