How did the weather forecast come from?

On November 4th, 1854, a storm suddenly appeared in the Black Sea in southern Europe. At that time, the British and French allied forces were fighting against tsarist Russia, and the British and French joint fleet was just moored on the Black Sea. The stormy waves rolled up the warships high and slammed them to the coast and rocks. In an instant, this huge fleet was wiped out by strong winds and waves.

The great storm caused unprecedented losses to the British and French allied forces. They named the big storm "Breckoff". It means "violent shock wave" So the French emperor Charles Louis Napolé on Bonaparte ordered the Paris Observatory to investigate how the storm was caused.

An astronomer named Le Weiye accepted this task. He collected meteorological data in many places around November 14th, and found that this big storm was caused by a low pressure. This depression first appeared in the western ocean of Europe, running from northwest to southeast, and reached the Black Sea, which caused this catastrophe. Le Weiye found out the origin of the "Breckoff" storm and wrote an investigation report, suggesting the establishment of a meteorological observation network, using telegrams to quickly transmit meteorological information and draw weather maps, so that the weather can be predicted. Since then, the weather forecast has gradually developed.
