How is the weather forecast produced?

1854165438+1October14th, a storm suddenly hit the black sea, with a wind speed of 30 meters per second, causing huge waves on the sea surface. The fleet of British and French allied forces assisted Turkey against Russia at sea and was almost wiped out. Later, the French War Department asked Le freire, director of the Paris Observatory, to study the ins and outs of the storm. He wrote to astronomers and meteorologists from all over the world, asking them to provide meteorological information for several days before and after the storm, and received 250 replies. According to the analysis of these reports, the storm originally came from the Atlantic Ocean and blew from west to east to the Black Sea. Two days before the accident, Spain and France were first affected. If there were weather stations and radio stations there and there were telegrams at that time, if the news of the storm was telegraphed to the British and French fleets as soon as possible, the losses could be reduced.

1855, le freire made a report in the French academy of sciences, saying that if a network of weather stations is established, concentrated in a main weather station by telegraph, analyzed and drawn into a weather map, it is possible to infer the whereabouts of the storm. At that time, society needed weather news. 1856, France established the world's first official weather forecast service system, which was a step forward than using proverbs to make forecasts.

From 65438 to 0856, the Paris Meteorological Bureau printed the weather map of the day every day. From 65438 to 0863, weather forecasts were published in newspapers and periodicals. Soon, other European countries also carried out meteorological work. Starting from 19 14, the data of various countries are brought together to draw a unified weather map of Europe.
