An autumn rain and a cold weather

Because for autumn, it is obvious that every rain is a sign of cooling down. After every rain, the weather is obviously lower than before. Therefore, there is a saying in our folk that an autumn rain is a cold. For our usual autumn, it is actually a season that everyone likes very much, because only autumn is the right temperature all year round, and for people in the north, autumn is the harvest season.

So for many of us, many people also like autumn very much. Although we often know that this is a popular saying, it is actually based on science. An autumn rain and a cold, in fact, most of the time refers to the drop of our temperature, but for the north of our earth, it is a natural phenomenon caused by cold air going south. In autumn, cold air goes south from afar until China and most parts of the south become warmer and wetter, and it will rain when the air meets. It is because of the rain that our temperature will drop, and the cold air again and again will cause our temperature to drop again and again, which forms a sentence, an autumn rain and a cold.

In fact, whether we know these related scientific knowledge or not, we can feel it from our daily life. Every time it rains, we feel that we should wear thicker clothes. This is the common feeling of most of us. As long as we go out for outdoor activities, we can feel the weather getting cold every time it rains. We wear long sleeves from half sleeves and then put on coats. So for our autumn, it is a scientific process of autumn rain and cold. Moreover, we must believe that these folk sayings are all summed up by our human wisdom, so we must pay attention to keep warm in autumn, protect our health, and don't let ourselves catch the flu.
