How does people's understanding of the atmosphere promote the making of weather forecast?

19th century, with people's basic understanding of the atmosphere, measurement technology has been improved. During the American colonial period, Benjamin Franklin first observed the storm in Philadelphia and learned that it subsequently swept through Boston, thus inferring that the meteorological system moved from west to east. Later, due to the widespread use of 19 telegrams in the 1950s, people summarized the observation results in a few minutes, and the real weather forecast was born. In this field, accurate records held by the military and merchant fleet are very important. At the same time, physicists and chemists discovered the laws governing the atmosphere, and meteorologists explained its dynamics. By 1900, several national meteorological services issued official weather forecasts.

Due to the appearance of weather balloons, radars and satellites, human beings sent "human eyes" into the sky in the 20th century. This idea was originally put forward by Norwegian meteorologist Wilhelm Picknice. Write atmospheric laws with equations to make the solution more accurate. Since the 1950s, computers have further developed this method. Using a lot of data processing, we can make a forecast map and also make a forecast for the unformed meteorological system. The overall characteristics of the global weather map can be predicted 10 days in advance. Although there are limitations, the prediction is very accurate. The weather forecast can predict the temperature and precipitation trend in a certain area 3 ~ 6 months in advance, thanks to the work of some scientists, such as Jakuber Pieckness, son of Welheim, who let people know more clearly about El Ni? o Southern Oscillation and other phenomena with global influence.
