How did the weather forecast come from?
The Origin of Weather Forecast Every day we can hear the weather forecast for the next day from china national radio. How did it come into being? This is also related to the war! 1854165438+1October 14, the night is dark and dark clouds are gathering. The Black Sea in southeastern Europe set off huge waves, followed by a terrible storm. The British-French joint fleet, which was fighting against the enemy at that time, had just arrived here and was immediately attacked by this storm. The main flagship "Arnli -4". Almost all the troops were wiped out. The storm caused great losses to the allied forces. The weather in Zhaoqing shocked the then French ruler Charles Louis Napolé on Bonaparte. He ordered Le Verrier, a famous astronomer at that time, the discoverer of Neptune and the director of the Paris Observatory, to make a comprehensive investigation into the motion law of the storm. Le Verrier immediately collected observation data from all over the country. The weather in Huadu is inquired in detail, and the weather conditions in various places from 165438+ 10/2 to 65438+February 16 are marked on a blank map. After careful study, Le Verrier was surprised to find that the Black Sea storm that attacked the British and French allied forces moved from the northwest of Europe to the southeast at a certain speed. Le Verrier believes that if there is a "weather map" in advance, then this storm can be completely avoided. Since then, "weather map" came into being. The earth where human beings live is surrounded by a thick "ocean of air"-the atmosphere. At the bottom of the "air ocean" is the air troposphere of about tens of kilometers, which is the main cause of climate change on the earth. The change of temperature causes air convection and forms air vortex. The movement of this air vortex formed a storm. Storms usually move in a certain direction at a certain speed from the formation site (usually on the ocean surface), and the moving direction and speed of storms are related to the temperature changes in various places. Therefore, if we summarize and analyze the climatic conditions in various places at this time, we can predict the movement of the storm. The weather in Shanghai became a weather forecast as soon as it was broadcast. In China, the observation results of local meteorological stations are summarized by the Central Meteorological Observatory, and then released to the whole country after analysis and research, which has become the' weather forecast' of the Central Meteorological Observatory. Now people have begun to use artificial satellites (meteorological satellites) to observe the climate in various places. After computer processing, the meteorological station can directly grasp the climate changes in various places and make timely and accurate weather forecasts. Now the weather forecast is not only used in military affairs, but also in industry.
