What does it mean to go back to the south?

Huinantian, also referred to as Huinantian, is a weather phenomenon in southern China. Returning to the south usually occurs in February and March in spring, which is the phenomenon of the weather returning to the tide. When "Return to the South" appeared, the air humidity was close to saturation, and the walls and even the ground would be "watery". There were wet scenes everywhere, and the air seemed to be able to wring out water. Because it is close to the sea, the air in the south is humid, so it is more serious. Thick fog is the most distinctive feature of "returning to the south sky" According to statistics, when the phenomenon of returning to the south is serious, the visibility can be reduced to 50 meters.

When winter goes and spring comes, it's warm and cold at first. People wake up and find the world outside the window is a vast sea of fog. This kind of weather is called "returning to the south sky" by people in Guangdong and Guangxi. Returning to Nantian is a phenomenon of warmer weather, which generally appears in February and March in spring. The main reason is that the warm and humid airflow quickly counterattacks after the cold air leaves, which leads to the increase of temperature and air humidity. Some cold objects are easy to produce water droplets when they meet warm and humid airflow. The phenomenon of returning to the south in the south is more serious, which is related to the sea and humid air in the south. When returning to Nantian appeared, the humidity of the air was close to saturation, and the walls and even the ground would be "water". Everything is wet, and the air seems to be wringing out. Thick fog is the most distinctive feature of "returning to the south sky" According to statistics, when the phenomenon of returning to Nantian is serious, the visibility can be reduced to 50 meters. In the weather of returning to South China, some items or foods are easy to get wet, which leads to mildew and rot. Therefore, appropriate moisture-proof measures should be taken.

Treatment method of surface moisture in Huinan sky

unfold a newspaper

Back to the south, you can spread the abandoned newspapers on the ground, which can absorb the wet water vapor on the ground and keep the room dry. At the same time, it can also play an anti-slip role, but it will affect the appearance.

Hot water with salt mopping the floor

You can also mop the floor with hot water and salt when you return to the south. Hot water evaporates very quickly, and at the same time it can take away excess water from the ground. In addition, salt can absorb water and keep the ground dry.

Lime dampproof

Quicklime has good water absorption. Sprinkle a proper amount of quicklime on the corner of the ground to absorb excess water vapor in the air and keep it dry.

The principle of returning to the south

From the meteorological point of view, after a long period of low temperature, the inside and outside of the object is completely cold. When the temperature of the object is less than or equal to the dew point temperature, the water vapor in the air reaches saturation and begins to condense on the surface of the object, forming water droplets and returning to the southern sky.

Back to Nantian is the name of a weather phenomenon in southern China. Usually refers to the phenomenon that the temperature begins to warm and the humidity begins to rise every spring. South China belongs to a typical maritime subtropical monsoon climate. Therefore, from March to April every year, the warm and humid air from the South China Sea meets the cold air from the north to the south of China, forming a quasi-static front in Lingnan, which makes the weather in South China changeable and very humid, with light rain or fog during the period, resulting in the phenomenon of returning to the south. When some cold surfaces encounter warm and humid airflow, they begin to condense and form water droplets on the surfaces.
