[Method] The current situations and business requirements of municipal meteorological networks are analyzed, putting forward the idea of backup routes that using VPDN-based 3G wireless meteorological information transmission system as the ground transmission line. And the network structure, operation mode and the system implementation are described in detail. [Result] VPDN-based 3G wireless meteorological information transmission system realizes the backup of ground line. Compared with the Modem dial-up, it is more stable and with faster transferring speed. With the rapid development of communication technology and computer technology, the information transmission system will be more efficient and stable, and will play a greater role in meteorological information transmission. [Conclusion] With the continuous development of modern meteorology, various types of meteorological data increase, presenting higher demand for the meteorological information transmission system. The established VPND-based 3G wireless meteorological information transmission system of this study provides a solution for backup transmission of real-time meteorological services.展开更多

The result shows that it is of great significance to actively adapt to the characteristics of information dissemination in the all-media era, establish and improve meteorological information service rules and supervision mechanisms, actively explore strong measures to strengthen the monitoring of meteorological services, promptly release authoritative voices, curb the breeding of rumors, regulate the propagation path, and conduct meteorological information dissemination assessment. Finally, this paper proposes the construction of meteorological information dissemination mechanism from five aspects: service quality assessment, introduction of enterprise information filing and credit management system, establishment of authoritative meteorological information sharing channels, formulation of emergency response plans, and vigorous promotion of meteorological popularization. The mechanism provides a theoretical reference for the meteorological department to better adapt to the all-media context and to carry out scientific and effective media-based public opinion information risk management.展开更多

As a higher education ＆ training organization previously, CMATC has been serving as the national base for higher continued education and on-the-job training in the meteorological field. The main tasks of CMATC are to pro- mote the training for the administrative staff at middle or higher levels in Chinese meteorological departments, such as the novel and high-level tech- nicians, operational backbones and instructors, and compile the meteorological training materials. On the other hand, a remote education ＆ training system of the meteorological division has been formed and largely improved. Additionally, we concluded that it should be a long-term development process for Chinese social education in meteorological field to entirely integrate into the current international settings.展开更多

The system consists of warning tips, early warning for different media and early warning query statistics and the network terminal of the system platform includes a business database server, a message platform database server, a sending server and a receiving terminal. The system enjoys some func- tions, such as examination by different users, on-time updating and effectiveness of flood prevention, construction of excessive warning channel, construction of compre-hensive warning information platform and further improvement of information distribution. The system provides references for prevention and reduction of important me- teorological disasters in Hunan.展开更多
