What are the phenomena of the southern return to the south? What exactly is Hui Nantian?

As a southerner, I am very familiar with the return to the south, when the return to the south is coming, it is usually very hot and humid, and water droplets will appear on the floor and wall one after another. Generally speaking, it is more uncomfortable to go back to Nantian, because returning to Nantian usually lasts for more than 3 days, and the whole house is wet when you go back to Nantian, and if the clothes or quilts are not stored properly, these things are likely to become moldy.

What should we generally pay attention to when returning to Nantian?

When returning to Nantian comes, as long as the windows and rooms at home are closed, this can effectively avoid the floor getting wet. It can't be said that it won't get wet 100%, but at least it can have a certain effect, and you can try this method when you return to the south of the sky. Also, if you go back to the south of the day, you must not let the clothes and quilts close to the wall, because if the quilt and clothes are close to the wall, when the wall becomes wet, the clothes and quilts will also be damp, and if you don't take them out to dry for a long time, they will become moldy and smelly.

When you go back to Nantian, you should also be careful not to mop the floor, some people look at the floor is a little damp and use a mop to mop the floor, but when you go back to Nantian, you can't mop the floor, the more wet it is.

When you go out, you must close the doors and windows of the house, it is not difficult that there is no one at home and the windows are not closed, then when you come home, it is estimated that it will be enough to choke. Of course, these are some basic knowledge will not be said here, southerners basically know what to do when returning to the south, if you are a friend who has just come to the south, you can refer to the above several methods, by the way, when you go back to the south, you can make some dampness soup to drink, so that it will be more comfortable.

There are a few times in the south from February to March every year, as a southerner, this is nothing, as long as it is handled properly, the floor at home will not be very wet. As long as you close the doors and windows when you go back to Nantian, the floor will not be very wet.

There will be weather tides, or when the temperature starts to rise, and it will also lead to an increase in air humidity, or a rapid return of warm and humid air. Enthusiasm will appear on the walls. I think it was in the spring in February and March.

The temperature will rise rapidly, which will lead to a phenomenon of reverse tide in the weather, which is called returning to the south.

There will be a lot of water on the wall, there will be a lot of water on the ground, the air in the house is very humid, the home is very cold, and a lot of wall skin will be dropped. Returning to Nantian is a special weather phenomenon. And only in the south.

The physics of the original eggplant in the south is that when the indoor temperature is low, the warm and humid air flow from the south comes into contact with the low temperature wall and other problems, forming water droplets, which is the most familiar feeling of wetness.

According to this principle, there are two situations for the elimination of returning to the south sky: one is the arrival of new cold air, which blows away the warm and humid air flow; Another situation is that the warm and humid air flow stays long enough to "warm up" the room, so that the internal and external tremors and liquid temperature difference between the indoor canopy potatoes are not large, and there will be no more return to the south of the sky.

The shape of the southerly wind is the warm and humid air that blows from the South China Sea, and meets the cold air from Siberia to the south, forming a quasi-stationary front in the south, making the weather in the south unpredictable and very humidDuring the period, there is light rain or fog, and the phenomenon of returning to the south is generated.

When the "back to the south sky" appeared, the air humidity was close to saturation, and the walls and even the ground would be "water", and there was a wet scene everywhere, and the air seemed to be able to wring out water. And the dense fog is the most characteristic appearance of "returning to the southern sky".

According to statistics, when the phenomenon of returning to the south is severe, the visibility can be reduced to 50 meters. In the weather of Huinan, some items or food are easy to get damp, and then mildew and rot, so it is necessary to take appropriate moisture-proof measures.

Moisture-proof method on southerly days

1. Try to minimize the temperature difference between indoor and outdoor. Before the "cold tail warmer" will "resurge", use heaters, electric ovens and other heat source equipment to heat the room, so that the indoor temperature is equal to or slightly higher than the outdoor temperature.

2. Try to isolate the intrusion of warm and humid airflow. Pay close attention to weather changes, once you find that the wind direction changes from north to south, you should close the doors and windows in time, and the indoor wardrobe and kitchen cabinet doors should also be closed tightly to reduce the entry of warm and humid outdoor air.

3. Put some moisture-absorbing and moisture-absorbing substances indoors. It is more economical and ideal to use quicklime (block lime), when lime melts, it absorbs water vapor in the air and releases heat, which has a warming effect on the room.
