Typhoon also ravaged France, so how did the French create a storm warning system?

1854 after the establishment of the research institute, several meteorological maps were drawn soon.

Even more farsighted is Auburn Levi, the new director of the Paris Observatory. Li Wei became famous when he discovered Neptune in 1846. Charles Louis Napolé on Bonaparte appointed him to succeed arago. Arago died a month after the Brussels meeting.

Levi, who is arbitrary, grumpy and ambitious, sees it as a good opportunity to make the Paris Observatory look brand-new and the French country "show its scientific spirit" to reappear.

Meteorology is one of Li Wei's main areas of concern. He realized that Britain and America were ahead of France, and joseph henry was still innovating at the Smithsonian Institution. 1854, Levi released his Great Initiative.

He formulated a framework: the observatory will be equipped with better instruments and publish weather records every day; At the same time, he will also set up a telegraph network and submit provincial data to the Observatory every day. "By adding a cable connection,"

He said, "different weather stations will be able to grasp the direction and wind speed of the expanding storm in real time; Therefore, it is possible to issue an early warning a few hours in advance before the strong winds along the coast, especially those extremely harmful hurricanes. "

This at least hints at France's new policy. Less than 65,438+00 years ago, arago wrote mercilessly: "Those who are honest and love feathers will never dare to predict the weather, no matter how advanced the science is."

Levi, who has just been in charge of the Paris Observatory for a few months, is vigorously promoting this cause. France's storm warning system ranks first in the world, and Levi's great achievements add a lot of color.

The technology involved in Li Wei's proposal far exceeds arago's idea in 1846. When Levi took office, the telegraph lines in Europe were as dense as cobwebs. Among them, Britain is the most developed country, and more than 90% of the population has a launch pad within Fiona Fang 10 mile.
