There were no meteorologists and satellites in ancient times. How did the ancients predict the weather?

In a word, the ancients judged the weather mainly by experience. It is because of these experiences that our ancients left so many meteorological proverbs, such as? Don't go out at sunrise, but go to Wan Li Road at sunset? 、? Yellow clouds in the evening, heavy rain in the Ming Dynasty? 、? Carp spots in the sky, no need to turn over the valley in the sun! ? Wait, these. Weather proverbs all come from the accumulated experience of ancient people. Many times, these proverbs can play their real role and can play a certain role in forecasting the weather. And those intuitive judgments about the weather actually come from the accumulation of experience. For example, when we see the sky overcast and even thunder and lightning, we know that it is going to rain in a high probability. There are no clouds in the sky. When the sky is clear, it must be sunny. These are all our experiences. Another source of weather forecast comes from ancient times, when there were special fortune tellers and diviners who could predict the weather through divination and divination. Of course, the accuracy of the weather forecast in this case is relatively low. But it also represents that the ancients had a preliminary understanding and understanding of weather phenomena. However, the understanding of meteorology in ancient times was not so systematic, because there was a serious bug in using these unscientific divination methods to predict the weather. The weather changes all the time and will be affected by various air humidity and temperature. Divination itself is unscientific, but when the weather is abnormal, they habitually use various superstitions to explain these phenomena, which makes people's understanding of the weather more difficult to be comprehensive. But the ancients were very familiar with the wind phase and the use of the wind. As early as the Shang dynasty, people could observe the wind direction by using the direction in which the flag fluttered.
