History of weather forecast

Before 1 and17th century, people made weather proverbs by observing the changes of the sky and objects to predict the local weather in the next few days, especially the common sense of "knowing the weather from clouds" was widely used. /kloc-after the 0/7th century, meteorological observation instruments such as thermometers and barometers appeared one after another, and ground weather stations were established one after another. At this time, the weather is mainly predicted according to the changes of air pressure, temperature, wind and clouds. However, the history of forecasting weather with weather charts is only 100 years.

2, 1820, Professor brandeis of Leipzig University drew the earliest weather map in the world, which created conditions for practical weather forecasting. /kloc-In the mid-9th century, Britain and France competed with Russia for the Black Sea Strait, and Britain and France sent a large number of fleets to participate in the war. 1854165438+1October14th, a strong wind blew on the Black Sea, which rolled up huge waves and threw the warships of the British-French joint fleet moored at sea to the rocks and the coast, causing great losses to the joint fleet. The French emperor Charles Louis Napolé on Bonaparte was shocked and immediately ordered the Paris Observatory to investigate the cause of the storm. Astronomer Le Ye Wei finally figured out the cause and effect of the storm by collecting and analyzing the meteorological data around Europe 165438+ 10/4, and wrote an investigation report. Le Ye Wei believes that as long as meteorological observation networks all over the country transmit meteorological conditions quickly by telegraph, they can immediately draw weather maps and make weather forecasts.

According to Le Ye Wei's suggestion, France and Britain started the weather forecast one after another, and soon spread to all parts of the world. Later, the means of observing the weather increased, especially the launch of meteorological satellites, which greatly improved the accuracy of weather forecasting.
