Historical Development of Meteorological Information Network

China Meteorological Communication Network Since the late 1950s, China Meteorological Communication Network has gradually developed into a domestic and international wired telex line. With Beijing as the center, offenbach, Moscow, Ulaanbaatar, Boli, Pyongyang and Tokyo are in line with international standards. Shenyang, Shanghai, Chengdu, Wuhan, Changsha, Guangzhou, Lanzhou, Urumqi, Taiyuan and Xi 'an all have regional meteorological communication centers. These centers are connected with provincial and municipal meteorological stations in charge of the region, and the meteorological stations are connected with subordinate meteorological stations. The regional center is responsible for the concentration and transmission of basic meteorological information in the region, the exchange of various meteorological information at home and abroad, the reception, processing and forwarding of foreign meteorological broadcasts in the region, and the organization of radio transmission, meteorological broadcasts and wired telex networks in the region. The communication network formed in this way, like the whole blood vessel of human body, is connected with international lines and stations all over the country, and thousands of meteorological data are exchanged day and night.

Since the mid-1970s, China has successively set up meteorological facsimile broadcasts in Beijing and regional centers, from which meteorological stations at all levels can obtain the tools and charts needed for making weather forecasts, thus reducing the repetitive work of receiving newspapers, drawing and analyzing. In particular, data such as satellite cloud pictures and numerical forecast products can be directly used to improve the timeliness and accuracy of weather forecast, carry out severe weather forecast and early warning, and better serve the national economy and national defense construction. There are nearly 2000 receiving stations in China.

In addition to radio transmission and fax, there are Morse meteorological broadcasts in China, which are located in Xi 'an and Taiyuan respectively, and are temporarily reserved mainly to solve the difficulty that some meteorological stations cannot improve communication conditions.

Since 1980s, China has introduced special electronic computers for communication, and built Beijing Communication Hub Center, which has realized the automation of communication processing and editing, and improved the communication speed. It has reached the level of "meteorological information * * *", that is, any station or unit connected to this system by full-duplex circuit in China can retrieve the required real-time data from the center and automatically agree to the remote inquiry.
