It's already the spring season, but the southern partners are about to usher in a wet day back to the south, and are constantly hurt. It is expected that this week the coastal areas of Guangdong and Guangxi will experience the phenomenon of "returning to the South". "Back to the South" is coming. Are you ready to prevent moisture?
Quick conversion of cold and warm air to make 'back to the South'
How powerful is it to go back to the south? Look, there is a picture with the truth.
Back to the south, the walls are sweating and the glass is writing
The clothes that can't be dried forever in "back to the South sky"
The corridor is covered with newspapers to dehumidify and prevent slipping
'the dehumidifier shows that the humidity is 97%, the wall is seeping, the floor is full of water, the glass is wet, and the quilt is wet. 'damn back buddy, five days ago, the laundry was not dry today, and it could still squeeze water out...' the horror of returning to the South could not help letting the small partners of the south make complaints about it.
Once back in the south, the children in the south are miserable: the glass windows are in the dark, the outdoor road is wet, the clothes are not dry, and the food is moldy. Returning to the south, mainly in South China, is a phenomenon of weather return tide. In February and March of each year, the warm and humid air from the sea increases, while the cold air in the north is still relatively active and frequently goes south, and the phenomenon of rapid conversion of cold and warm often occurs. After the cold air is gone, the warm and humid air flow quickly counterattacks, the temperature rises, and the air humidity increases. However, the temperature of indoor floor, glass and other objects rises slowly. When the cold surface meets the warm and wet air flow, it is easy to condense water.
Hu Xiao, chief analyst of China Weather Network, said: "generally, there are two conditions for" returning to the South "phenomenon. First, the daily average temperature lasting for more than three days is lower than 14 ℃; the other is that the temperature suddenly warms and the humidity increases. It's like walking into a cold and dry bathroom in the north and suddenly turning the hot water to the maximum. Soon, there will be water droplets on the ceiling and walls of the bathroom. '
In the spring of 2012, Guangdong experienced the most serious phenomenon of returning to the south in recent years. According to the statistics of Guangdong Provincial Meteorological Station, at that time, strong cold air from the North frequently went southward, coupled with the influence of warm and humid air flow, a large-scale and long-lasting rain and fog weather and "returning to the South" phenomenon appeared in Guangdong from February to March. According to the statistics of Zhang Dong, chief forecaster of Guangdong Meteorological Station, there were five "back to the South" process in Guangzhou from February to March 2012, which were February 6, 13-15, 21-24, March 4-6 and 15-18. The serious "huinantian" made the quality of greenhouse vegetables in Guangzhou decline, and the prices rose accordingly.
How to prevent dampness is the key point this week
It is expected that starting from Tuesday (February 26), with the temperature rising slowly and the air humidity increasing in South China, a slight "returning to the South" phenomenon will appear in the coastal areas of Guangdong and Guangxi. It will be relieved later in the week.
The harm of huinantian to the people in the south is not only wet everywhere, but also mildew and damage to quilts, clothes, furniture and household appliances for a long time; it is easy to induce respiratory tract, cardiovascular and skin diseases. So how to prevent dampness? You need to go back to the south to prevent dampness
1. Close the doors and windows: the simplest way to prevent moisture is to close the windows in your home, especially those facing south and Southeast. Otherwise, water vapor will invade the house. In addition, the most important period of moisture prevention is morning and evening. From 6:00 a.m. to 9:00 a.m. and from 8:00 p.m. to 2:00 a.m. of the next day, the air humidity in these two periods is higher than that in other periods, so it is necessary to close the doors and windows. If you want air circulation, you can open the window at noon for ventilation.
2. Salt water mopping: warm salt water mopping, just add a few spoonfuls of salt into warm water. After the salt is fully dissolved, soak the mop in the salt water, and then start to mop the floor after wring it dry. In addition, you can turn on the air conditioner and turn on the dehumidification function, or use a dehumidifier to keep the room dry.
3. Clothes moistureproof: dry tea can be packed into gauze bags and placed in different places, which can not only remove the musty smell, but also make clothes emit fragrance. In addition, you can also put activated carbon into the wardrobe, and remember to close the closet door.
4. Common household appliances: increase the frequency of use, household appliances will generate heat during operation, which can effectively disperse moisture. If you don't use it for a long time, you'd better electrify it once or twice a day. In the use of electrical appliances, to keep the power plug, socket and switch dry, less or no drag line plug, to prevent electric shock and other accidents.
