What is it that there are always red envelopes in the weather forecast?

The weather forecast is a national red envelope, so it's best not to take it, and some are afraid of junk advertisements.

Three thousand years ago, there were records about weather in Oracle Bone Inscriptions, China, including wind, clouds, rainbow, rain, snow, frost, haze, tornado, thunderstorm and so on. Because a large number of weather events were recorded in writing, some intellectuals finally got to know the climate. In ancient China, we observed astronomy and meteorology, worked out calendars, and understood and predicted the climate.

The most clear purpose is to arrange agricultural production, sacrifice and other activities. Oracle Bone Inscriptions also reflected that people already had the requirement of forecasting weather conditions, which were all adapted to the needs of agricultural production at that time. As early as the Spring and Autumn Period, the ancients set four solar terms: midsummer, midsummer, midsummer and winter solstice. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established.

According to the theory of "destiny", sunrise, sunset and ebb and flow of tides are all natural periodic changes. People can make more accurate predictions about these periodic changes. However, people often can't see the regular sunrise, sunset and ebb and flow. At this time, people expect to know those irregular phenomena in advance.

Since ancient times, intellectuals in China have been concerned about the prediction of astronomy, earthquakes and meteorology. Dong Zhongshu, an ancient thinker, put forward the slogan of "bending people and extending the monarch, bending the monarch and extending the sky". The first sentence is to ask the subjects to obey the emperor. The last sentence is to ask the emperor to listen to God's will. God limited the emperor's actions. Most of these phenomena come from ignorance of the sky (such as solar eclipse) and the earth (such as earthquake).
