Why is the weather forecast unreliable?

Because the weather has been changing.

After the predicted moment, it will not remain unchanged.

The weather system is not only an atmospheric problem, but also a comprehensive system, which is the result of the interaction of five circles. Human understanding of the laws of atmospheric motion is still very limited.

Little is known about the interaction of five spheres. In addition, under the background of global warming, the probability and frequency of extreme weather and climate events increase. The influence of the Qinghai-Tibet Plateau and local topography can make the weather change more mysterious, and the influence of the Qinghai-Tibet Plateau can even change the global weather and climate.

Weather forecast, first of all, is to collect meteorological data, from the ground to the sky, from the land to the ocean, to observe the atmospheric changes in an all-round and multi-level way, and then the computer will process and calculate the collected data to get weather maps, numerical forecast maps and other products.
