What is the TV weather forecast?

In a large-scale storm, the public knows to rely on TV to provide them with the information they need. But the weather during the storm was not as bad as reported on TV. Producers only arrange the weather forecast after the news because they find that the weather is the main reason why people watch TV news.

Many TV meteorologists are not meteorologists. In the early days of TV development, this situation has hardly changed. The TV station hired local beauties, puppet artists and clowns to explain the weather. Some weather forecasts are expressed or sung in rhymes or cartoons. The best drawing is only described with a chalk board. The clown's practice has not disappeared. A famous Australian host uses an indicator every time he goes on TV, and even puts an icicle and an ice cream cone under the glare of the studio.

However, according to their scientific knowledge, academic qualifications and accuracy in front of the camera, some of them have been recognized by the national meteorological department. In the United States, many radio stations broadcast the weather themselves, but they are also guided by the National Weather Service. In some big cities and areas with bad weather conditions, meteorologists have Doppler radar earlier than their counterparts working in the government.

Many radio stations have a large number of voluntary organization networks, and voluntarily call to report local weather conditions. Meteorologists and image experts work in TV stations and make full use of computers to make local three-dimensional simulated maps, charts and "cyclones". They check these imperfect data, talk to observers, make format predictions, choose pictures, quickly write down their geographical location, and often play them on radio or TV several times.

However, as a TV meteorologist, it is not easy to work with a smile under great pressure. The weatherman pointed out that every chart is not easy, let alone on TV. Because the weatherman is in the studio, standing in front of the dark green or blue wall, imagining all kinds of plots. They must remember these scenes. A montage technique called color map produces a composite image that viewers can see at home. In this process, the computer will eliminate every special color on the TV image. For TV, use the computer editor in the broadcast control room to choose green (or blue), so as to eliminate the blank wall behind the weatherman. A weather map or satellite photo with a green (blue) background will be automatically inserted on it, and the picture will be transmitted in a synthetic way. Understandably, the TV weatherman is very careful not to wear clothes with inappropriate colors.
