What is the cause of the weather phenomenon?

The changes of weather and climate, wind, frost, rain and snow are very important to people's life and production practice. Dressing, walking and even life are inevitable.

In the long-term production practice, people have struggled with heaven and earth, gradually mastered some meteorological knowledge, and predicted the weather according to objects and sky phenomena.

As early as 3000 years ago in Shang Dynasty, China used Oracle Bone Inscriptions to record weather conditions such as wind, rain, drought and waterlogging. This is the meteorological record of Oracle Bone Inscriptions in Shang Dynasty in BC 12 17. The words on it are: Gui Hai Bu, Ding (true) 10th. March. Ugly, evening (night), rain. Ding Mao, Ming, Yu. E (Chen), small mining day, rain, wind. Self (fourth), Ming, Qi (Ji). Ren Shen, the wind comes from the north.

For the reasons of weather phenomena, some phenomena were explained by ancient people in China. The book "Zhuangzi" said: "A large breath is called the wind." This shows that the wind is formed by air flow. Zhu explained the cause of rain in the Southern Song Dynasty: "Steaming is rain, like rice retort, steaming is sweating." He also said that Lou didn't land. Li Shizhen's Compendium of Materia Medica said: "Those who expose themselves will wet the roadside at night."

There are detailed meteorological records in China ancient history books and local chronicles. Since the Han Dynasty, special weather such as drought, severe cold, frost, snow and hail has been recorded, especially in the capital areas of various dynasties.
