"The Origin of Weather Forecast" 1 question~~Guaranteed to add 50 points

Get the points, haha.

To put it simply, it is based on the surrounding weather (wind force, wind direction, movement trajectory, movement speed and the surrounding geographical environment (mountains/oceans/plains) etc.) and the influence of air pressure, to predict)

There were no telephones at that time, so Lefrier could only write letters to astronomical and meteorological workers in various countries and collect from them the data from November 12 to 16, 1854. Local weather information for the next 5 days. He received 250 replies in one ***. Based on this information, through careful analysis, reasoning and judgment, Lefrier found out that the Black Sea storm came from the vast Atlantic Ocean and swept across Europe from west to east. Two days before the accident, that is, November 12 and 13, Spain and Spain in western Europe France has been successively affected by it. Lefrière looked at the erratic clouds in the sky and fell into deep thought: "This storm seems sudden on the surface, but in fact it has a development and movement process. The telegraph has been invented. If there were any equipment along the Atlantic coast of Europe at that time, If the meteorological station telegraphs the situation of the storm to the British and French fleets in time, disastrous losses can be avoided."

So, on March 19, 1855, Lefrière gave a report at the French Academy of Sciences, if By organizing a network of meteorological stations, using telegraphs to quickly gather observation data into one place, and analyzing and drawing it into weather maps, it is possible to deduce the path of future storms. Lefrière's unique hypothesis aroused strong repercussions in France and around the world. People have deeply realized that correctly predicting weather is not only beneficial to marching operations, but also has great benefits to industrial and agricultural production and daily life. Due to the needs of various aspects of society, under the active promotion of Leverier, France established the world's first formal weather forecast service system in 1856.

The birth history of weather forecasting shows that meteorological conditions can affect the victory or defeat of local wars or wars, and the needs of war have promoted and developed meteorological undertakings.
