15 weather forecast for February 6th.

From a long time ago, human beings have been fed up with bad weather since they were born, hoping to predict the weather one day. But this effort did not succeed.

The turning point of the incident occurred in the Crimean War of June 5438+0854+065438+ 10/4, and the British-French joint fleet fought a decisive battle with Russia in the Black Sea. When the joint fleet seized the port and prepared to land, a storm with a wind of112 hit, sinking more than 30 ships of the joint fleet, including the French flagship, and its strength was greatly weakened. Afterwards, Le freire, director of the Paris Observatory, was appointed to investigate the cause and effect of the storm. He wrote letters to meteorologists all over the world and collected meteorological reports from June 1854+065438+ 10/2 to June 16. * * * 250 replies were received. He filled these data into the map (hereinafter referred to as the weather map) and found that the storm moved regularly from west to southeast, which had caused disasters in France and Spain a day or two ago. So, on March 1855, he made a report in the French Academy of Sciences, suggesting that a network of weather stations should be organized, and they should be concentrated in one place by telegraph (invented at that time), and the future path of the storm can be predicted by analyzing the trend of the storm on the map. 1856, France realized weather chart forecast for the first time, and set up storm warning service. This is the first country in the world that regards meteorological work as a national cause. By the end of 19, 2 1 countries in the world had established specialized meteorological institutions. China is in 1906.

Social demand is a powerful driving force for scientific development. Although meteorological disasters continue to sow the seeds of conquering oneself (weather forecast), this seed can not germinate casually. For example, our country was founded by agriculture in ancient times, and farming also needed weather forecast. China has become one of the countries with the most meteorological disasters in the world because of the monsoon climate that changes greatly year after year. However, weather map forecasting was not first born in China.

It turns out that philosophically, even if the social demand is very strong, it is only an external cause. External factors need to work through internal factors, so that contradictions can be transformed and weather map forecasting can be born. Of course, for the needs of agriculture and life, China has accumulated a wealth of weather (forecast) proverbs and experiences for thousands of years. However, due to the lack of scientific theory and the observation of modern meteorological instruments, the forecasting factors cannot be quantified and can only stay in the qualitative experience stage. Western countries have barometers, so they have barometric values. With the pressure value, there are isobars, weather maps and weather forecasts.
