Why do descriptions of extreme weather and meteorology often appear in the ancient book Zi Tong Zhi Jian, but there are few reports and occurrences of extreme weather in modern times?

1. This is the embodiment of the ancient theory of heaven-man induction in historical narrative. Whenever the emperor's rule goes against God's will, there will be some omens to warn him, and even disasters will be punished.

The appearance of extreme weather will definitely affect the development of history. For example, the climate is cold, and nomadic people in the north usually have a hard life and have to invade the Central Plains. For example, the serious drought in Shaanxi in the late Ming Dynasty triggered the Li Zicheng Uprising.
