What is the significance of meteorological information network?

Meteorological stations and various detection facilities all over the world form an observation network to monitor weather changes around the clock and capture various meteorological information in the earth's atmosphere. The information obtained by these outlets is quickly concentrated to meteorological centers or communication centers in various countries through wired and wireless telegrams and telexes, and sometimes it has to be transferred several times. From each center, it is sent by wired or wireless telegram, telex and broadcast for use by meteorological stations and commercial units all over the country. Meteorological stations, meteorological centers and various business units make these information into various finished products, and send them to the global or domestic and local countries through various means of communication, as well as to users in specific regions, specific departments and specific regions for use or meteorological services. In this way, a cascade of meteorological information networks with different scales and functions has been formed around the world, with large coverage of the whole world and small coverage in local areas. On these networks, hundreds of millions of meteorological information are exchanged day and night.

The transmission of international meteorological information is mainly undertaken by the world weather broadcasting network and the meteorological special line network.

Some meteorological information obtained by various detection means in the world is for the international public, concentrated in 86 meteorological communication centers around the world, and then broadcast by region. The global * * * is divided into 8 broadcast areas, and each area has 8~ 1 1 centers. These central parts are the capitals of various countries, and Peking in China is one of them. Local meteorological stations can choose to receive broadcasts from any center as needed, and draw the received meteorological telegrams on the weather map, so that the five continents can have a panoramic view.

In addition to the above-mentioned wireless broadcasting network, an international wired telegraph network has been established. Washington, Moscow and Melbourne are 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.
