Under the influence of the return to the south of the sky.
Many places in the south have become "water curtain holes".
In the process of returning to the south for nearly a week.
Can residents only close their doors and windows to "avoid the south"?
Some netizens are on the official Weibo of the Guangzhou Meteorological Department.
Leave a message asking if you can open the window to breathe when the sun comes out
In response to this question, the Guangzhou Meteorological Department replied.
Members of the public can enjoy relatively high temperatures at noon.
And when there is sunlight, open the window appropriately to ventilate.
If the above conditions are not met.
It is also possible to reduce the "south" of the room by raising the indoor temperature
According to the forecast of the Shenzhen Meteorological Observatory, in the next few days.
Shenzhen will continue to be affected by warm and humid airflows.
The phenomenon of "returning to the south of the sky" will be more obvious.
Therefore, the public is advised to pay attention to the issue of moisture prevention.
Pay special attention to traffic safety in rainy and foggy weather.
The weather will get cold before the Chinese New Year holiday.
When the sky returns to the south, the air humidity is close to saturation, and the walls and even the ground will be damp. Generally speaking, two weather conditions are required for the phenomenon of returning to the south: one is a period of low temperatures, and the other is a sudden change in weather. After a long period of low temperatures, it suddenly becomes warm and humid. Why is there so much water vapor? In fact, after entering February and March, South China began to feel the warm and moist air from the sea, that is, the southwest monsoon. However, at this time, there will be cold air from the north to replenish it from the south. When the warm and humid air moves northward, it encounters a violent collision of cold air from the south, forming cloudy, rainy, and foggy weather, and the water vapor can easily reach a saturated state, and the phenomenon of "returning to the south sky" will quietly attack.
It is recommended to close doors and windows in time.
Increase the indoor temperature to slow down the humidity.
Many people have some questions about the question of "whether to turn on the air conditioner, air conditioner or heating when I come back to Nantian". The Shenzhen Meteorological Observatory said that the use of air conditioning can indeed play a certain role in dehumidification. One might ask, "Why turn on the air conditioner when the water vapor can be evaporated by the heat?" ”
Experts from the Meteorological Observatory said that in fact, this is explained according to the principle of physics, and that water in the air condenses into droplets when it is cold. When the air in the room comes into contact with the cooler, the water droplets condense and expel outside, acting as a dehumidifier. If there are elderly or children at home who are not very tolerant to cold, it is not recommended to turn on the air conditioner for dehumidification, and you can use dehumidifiers, activated carbon, moisture absorption packs and other methods to eliminate moisture in closed spaces, such as drawers, shoe boxes, wardrobes and other places; Or use newspaper to spread on the floor, which can not only play a non-slip effect, but also absorb moisture.
The Meteorological Observatory reminds that the phenomenon of returning to the south will become more and more obvious in the next few days, please close the doors and windows in time and raise the indoor temperature to slow down the humidity. At present, light fog has appeared in some areas of Guangdong, please pay attention to traffic safety when traveling. In addition, during the Spring Festival travel period, rain, snow and freezing weather in the central and eastern regions before the Spring Festival will affect the Spring Festival transportation such as roads, railways and flights.
