Play the weather world

The birth of the world's first weather map was related to a war.

1854165438+10, the famous Crimean war in history is going on fiercely. The British and French allied forces surrounded Sevastopol, and the Marines were preparing to land in the Black Sea port of Balaclava. At this time, a strong wind suddenly blew in the Black Sea, causing huge waves. The British and French allied forces collapsed without fighting, and almost all the troops were wiped out.

At the request of the military, Le freire, director of the Paris Observatory, studied the storm. He wrote letters to meteorologists all over the world and collected weather reports before and after the storm. After collecting the meteorological report, he filled in the meteorological conditions of different places at the same time on a map in turn. By analyzing the maps at different times, he found that the storm moved from west to east, and it had already affected Spain and France 1~2 days before reaching the Black Sea.

After analysis, Lefler thought that if there were weather stations in Europe at that time, the storm situation could be telegraphed to the British and French fleets in time, so that the British and French fleets could avoid the attack of the storm. In March 2008+0855, he suggested to the French Academy of Sciences that an observation network should be organized to quickly collect observation data, analyze and draw weather maps in one place.
