What kind of weather often appears in South China in spring?

Returning to Nantian, mainly in South China, is a phenomenon of warmer weather. Every spring, the warm and humid air flow from the sea increases in February and March. At this time, the cold air in the north is still active and frequently goes south, which often leads to a rapid change between cold and warm. After the cold air leaves, the warm and humid airflow quickly counterattacks, the temperature rises, and the air humidity increases, while the temperature of indoor floors, glass and other objects rises slowly, and the surface of cold objects is easy to condense water after encountering the warm and humid airflow.

Prevention methods of returning to the south sky

1, close the window in the morning and evening

When the damp "returning to the south sky" strikes, everyone must remember to close the windows at home, especially those facing south and southeast, so as not to give any chance for the moisture eyeing outside the window to sneak in. The most important period of moistureproof is in the morning and evening of every day. The air humidity in these two periods is higher than that at noon. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the house. In addition, if you think that the indoor air cannot circulate because the doors and windows are closed, I suggest you open the window for a short time at noon.

2, hang desiccant

There are many desiccants specially used for moisture prevention and dehumidification in the supermarket. The most common types are moisture absorption boxes and bags. Many water-absorbing boxes have various scents, such as lemon, lavender, sweet orange, etc., which can make the house full of scents and are suitable for being placed in living rooms, rooms, bathrooms, kitchens and other large spaces in daily life. After using it for a period of time, you can take out the substances in the moisture absorption box and buy bulk desiccant and put it in the box for reuse.

In addition, the dehumidifying bag made of water-absorbent resin and charcoal is more suitable to be placed in narrow spaces, such as closets such as wardrobes and shoe cabinets, and a bag of dehumidifying bag can be hung to discharge moisture.
