The China Meteorological Administration has always had the tradition of weather discussion through video conferences, but due to the technical conditions, the meteorological video conference system can only be used via the meteorological intranet for many years. In order to meet the needs of users to access the video conference system based on internet, the National Meteorological Information Center has completed the cloud video conference system in 2019. Relying on domestic Internet video conference products, the system is deployed in the way of private cloud, and realizes the integration with the existing meteorological video conference system based on H.323 protocol. Setting up a friendly enterprise mode among multiple cloud consultation systems meets the requirements of system classification and localized management of meteorological departments. It also dramatically improves the simplicity of interdepartmental consultation and linkage. In this paper, the system’s design scheme and key technologies are described, and the application effect of the system in meteorological services for significant events and the process of meteorological departments fighting the COVID19 epidemic is introduced. The development direction of the cloud consultation service is also proposed.
