Hui Nantian refers to every spring, when the cold air transits, the warm and humid airflow is rapid, resulting in the temperature rising, the air humidity increases, and some cold objects encounter warm and humid air flow, which is easy to produce water droplets, this phenomenon is called Hui Nantian.
Genesis. Hui Nantian is common in southern China, because of the monsoon, the wind direction in the region is the south wind blowing from the Pacific Ocean to the land in spring, and the dry and cold north wind in winter, which is affected by the warm and humid sea breeze and the cold and dry north wind. In February and March, the power of the cold air mass in the north weakens and the power of the warm air mass in the south increases, so that the water droplets condensed on the surface of the object condense again after evaporation, so there will be many times to return to the south.
The characteristics of Hui Nantian are:
The temperature is rising, and the air humidity is increasing.
The surface of the object is prone to water droplets.
The floor is damp, the walls are seeping water, and the clothes are damp.
Effect. Returning to Nantian will bring some inconvenience to people's lives, such as:
The ground is wet and easy to slip, so attention should be paid to non-slip.
A humid environment is prone to the growth of bacteria, so attention should be paid to indoor hygiene.
Electrical appliances are prone to failure when exposed to moisture, so attention should be paid to the safety of electrical appliances.
Some measures to deal with the return to Nantian:
Close doors and windows: Prevent humid air from entering the room.
Use a dehumidifier: Reduce the humidity of the indoor air.
Wipe down furniture: Protect furniture from moisture.
Pay attention to non-slip: The ground is wet and easy to slip, so you should pay attention to anti-slip.
During the return to Nantian, the following should be noted:
Pay attention to non-slip to avoid falling.
Pay attention to indoor hygiene to prevent the growth of bacteria.
Pay attention to the safety of electrical appliances to prevent electrical appliances from malfunctioning when they are damp.
The return to the south usually occurs in February and March in spring, but the exact time varies depending on the region.
The phenomenon usually lasts for a few days, but it can last longer.
The phenomenon of returning to Nantian has no direct impact on human health, but it is necessary to pay attention to moisture-proof and anti-slip.
