Hui Nan Tian, ​​also known as south wind day, refers to the phenomenon that the temperature begins to warm up and the humidity rises sharply every spring. Humidity is a weather phenomenon that is common in South China in winter and spring. It is characterized by very humid air and water droplets on the walls and floors. The main reason for returning to the south is that after the cold air moves away, the warm and humid air quickly counterattacks, causing the temperature to rise and the air humidity to increase. When the surface of some cold objects encounters the warm and humid air, it is easy to produce water droplets, so the common people call this kind of weather " Go back to the south."
