Principle of meteorological information network
In addition to the above-mentioned wireless broadcasting network, an international wired telex network has been established. Washington, Moscow and Melbourne are the three world centers; Bracknell, Paris, offenbach, Prague, Nairobi, Cairo, New Delhi, Brasilia, Tokyo and Beijing are regional communication hubs. The center and hub are connected with meteorological centers, meteorological stations and meteorological business units in many countries and places, forming a telex meteorological information network. Through the data channel and fax channel of this network, a large number of formal and informal meteorological data, weather live maps and forecast maps are transmitted. This telex network has the advantages of heavy load, convenient receiving and sending, rapid and timely transmission, and also transmits a large number of contents that wireless broadcasting can not transmit.
