The weather forecast of CCTV is about a few minutes.

Generally 2-3 minutes, special weather will increase by about 2 minutes.

CCTV weather forecast was born on July 7th, 1980, and it is also called "News Network Weather Forecast" because it is broadcast immediately after CCTV news network broadcast.

At the beginning of the broadcast, the daily manuscript was written by the Meteorological Observatory and then faxed to the TV station. The map used is a 24-hour forecast map, and the announcer speaks around it. At that time, there was no technical gold content, and it was done by hand every day (drawing with a duckbill pen after pencil drawing). After painting, CCTV sent a car to pick it up.

1985, the audience saw the cartoon cloud picture of typhoon taken by satellite. Later, the weather forecast of China's responsible sea area was added to provide meteorological services for maritime shipping, fishing and exploration (noon news broadcast on February 6,1989); In addition, the typhoon forecast map has been added in summer.

With the establishment of a new generation of radio and television weather forecast production system, 1993 TV weather forecast has ushered in another major breakthrough. As far as the background image is concerned, there are three-dimensional weather symbols in form; In terms of content, the limit of national weather trends has been extended from 24 hours to 48 hours.

In the 2 1 century, new background pictures are constantly added or updated. On March 3, 2003, the forecast time limit was extended to 72 hours again. In addition, according to the different needs of the audience for meteorological information, a series of popular science columns such as 24 solar terms, spring sowing weather, wheat harvest weather, various disastrous weather causes, disaster prevention and mitigation, one-week weather review, weather and climate review, holiday weather, weather and climate in Hong Kong and Macao, weather and climate in the Three Gorges of the Yangtze River, weather knowledge and terminology have been successively launched.

At the beginning of 2004, the maximum temperature forecast was added, aiming at the five-day weather forecast which has great influence on the weather;

On June 5438+1October 18, 2005, the "Space Weather Warning" was first released to the public by using the monitoring data of FY-2C.

In short, there are traditional short-term forecast and early warning, medium-term forecast and prospect, regional monitoring and early warning, case analysis of typical cities or regions, weather interpretation of current hot events and so on. These, science and technology have made indelible contributions, and also proved that the content of gas forecast is getting richer and richer, and the basis of weather forecast is getting more and more accurate.
