How was weather forecast invented?

Weather forecast is based on meteorological observation data, using the principles and methods of meteorology, dynamics and statistics to make a qualitative or quantitative forecast of the weather conditions in a certain area or a certain place in the future. Accurate weather forecast has always been an important goal of atmospheric science research. Weather forecast is based on meteorological observation data, using the principles and methods of meteorology, dynamics and statistics to make a qualitative or quantitative forecast of the weather conditions in a certain area or a certain place in the future. Accurate weather forecast has always been an important goal of atmospheric science research. Knowing the weather from clouds → inferring the weather from objects → single station forecast → weather map forecast → application of meteorological satellites and weather radar → computer forecast. With the continuous progress of science and technology, weather forecasting has developed rapidly. According to the prediction time limit, it can be roughly divided into: imminent earthquake prediction (1 ~ 2 hours), extremely short-term prediction (2 ~ 12 hours), short-term prediction (12 ~ 48 hours), medium-term prediction (3 ~ 10 days) and long-term prediction (. Weather forecast method (or weather map method): a method of making weather forecast with weather map, satellite cloud map and radar map as the main tools. Analyze and study the changing law of weather with the principle of meteorology. This method is mainly used for short-term forecasting. Numerical forecast method (also known as dynamic forecast method): a method of weather forecast by solving the dynamic equation describing atmospheric motion with a large-scale fast computer. This method can be used for both short-term and medium-and long-term forecasting. In recent years, it has also been used for climate prediction. Statistical forecasting method: based on a large number of long-term meteorological observation data, according to the principle of probability statistics, find out the statistical law of weather change, establish the statistical model of weather change, and make the weather forecast method. This method is mainly used for medium and long-term forecasting and meteorological element forecasting. Nowadays, when people go out, they can decide whether to bring rain gear by listening to or watching the weather forecast. In the past, they had to worry about unexpected things. So, how is the most important weather forecast of meteorological stations born every day? 1853- 1856, the Crimean war broke out between tsarist Russia and Britain and France for the Balkans, and Russia was defeated as a result. It was this war that led to the appearance of weather forecast. This is a huge naval battle.1854165438+10/4. When the two sides launched a fierce battle in the Black Sea of Europe, the storm suddenly came, the maximum wind speed exceeded 30 meters per second, and huge waves were set off on the sea, which almost wiped out the British and French fleets. Afterwards, the British and French allied forces were still concerned. The French War Department asked Le freire, director of the Paris Observatory, to study the cause and effect of the storm carefully. At that time, there was no telephone. Le Freire only wrote letters to astronomers and meteorologists all over the world to collect local weather information during the five days of1854112 ~16 in October. He received 250 letters at once. According to these data, after careful analysis, reasoning and judgment, Lefler Ray found that the Black Sea storm came from the vast Atlantic Ocean and swept across Europe from west to east. Two days before the accident, namely 1 12 and 13 in October, Spain and France in western Europe have been affected by it successively. Le freire looked at the drifting clouds in the sky, lost in thought: "This storm looks sudden on the surface, but in fact it has a process of development and movement. The telegraph has been invented. If there were weather stations along the Atlantic coast of Europe at that time, wouldn't it be possible to avoid heavy losses by telegraphing the storm to the British and French fleets in time? " So, on March 1855 and 16, Lefler Lei made a report at the French Academy of Sciences, saying that if a network of weather stations was organized, the observation data were quickly concentrated in one place by telegraph, analyzed and drawn into a weather map, it would be possible to infer the running path of future storms. Le freire's unique idea has aroused strong repercussions in France and even the whole world. People deeply realize that accurate weather forecast is not only beneficial to marching operations, but also beneficial to industrial and agricultural production and daily life. Due to the needs of all sectors of society, with the active promotion of Le freire, France established the world's first official weather forecast service system in 1856. Weather forecast is a basic forecasting service program. In the numerous weather and climate-oriented programs on the weather channel, the weather is interpreted with popular language and rich pictures and texts, and the most authoritative weather forecast and early warning information is released at the fastest speed. At the same time, it introduces meteorological knowledge, provides traffic information, and provides life reference for health, travel and diet from the perspective of weather. Weather forecast has become an indispensable part of people's lives since it was broadcast. Knowing the weather early is conducive to making all kinds of preparations for going out. China TV weather forecast is broadcast from1981101. At that time, the method of video and dubbing was adopted, and the host did not appear on the screen. 1993, the weather forecast hosts Song Yingjie and Zhao Hongyan became the first weather forecasters to appear on TV, which changed the situation that the weather forecast only had voice but no one was there. Later, Pei Xinhua and Yang Dan joined the host team of weather forecast. 200 1 the host gave up the pointing stick used to point out the weather on the map and pointed to the map with his finger. The quality of CCTV weather forecast has also reached a higher level. In 2007, using the new graphics system, the host began to use the background graphics remote controller.
