Autumn rain turns cold.
In fact, this is an autumn rain, a common cold. 10 After the autumn rain, the temperature will drop. According to the experts' explanation, although the hot air in beginning of autumn is hard to disperse, it is believed that the autumn tiger is still at work, but generally speaking, the weather tends to be cool, and the temperature difference between morning and evening begins to become obvious. It is often hot during the day and cool at night.
After entering autumn, cold air will enter most parts of China from Siberia and Mongolia every year. At this time, they will meet with the falling warm and humid air in the south, thus forming rain. When the cold air goes south again and again, it will cause rain again and again, which is why the local temperature is lower every time.
In addition, during this period, the direct sunlight gradually moved southward, and the light and heat received by the northern hemisphere decreased day by day, which was also conducive to the enhancement and southward movement of cold air. After several cold air moves south, the local temperature will drop obviously, which is why there will be an autumn rain and a cold.
After a heavy rain, it is probably late autumn and early winter. At this time, people have to wear cotton-padded clothes to keep out the cold, so that's why the above proverb came into being.
In fact, in detail, there are many proverbs about the weather in our life, which are summed up by the older generation according to their own perennial experience, comparable to the weather forecast. The ancients also used this method to predict the wind and rain, such as frogs calling for heavy rain and swallows flying low to rain.
