How to prevent moisture in the south wind?

The formation of southerly sky is a warm and humid airflow blowing from the South China Sea, which meets with the cold air coming south from Siberia, forming a quasi-static front in the south, making the weather in the south uncertain and very humid, with light rain or fog in between, resulting in the phenomenon of returning to the south sky.

when "returning to the south sky" appeared, the air humidity was close to saturation, and the walls and even the ground would be "bubbling", and there were wet scenes everywhere, and the air seemed to be able to wring out water. The dense fog is the most distinctive appearance of "returning to the south sky".

according to statistics, the visibility can be reduced to 5 meters when the phenomenon of returning to the south sky is serious. In the weather of returning to the south, some items or foods are easy to get wet, and then mildew and rot. Therefore, appropriate moisture-proof measures should be taken.

moistureproof methods in southerly days

1. Try to reduce the temperature difference between indoor and outdoor. Before the "cold tail and warm head" will regain moisture, use heat source equipment such as heater and electric oven to heat the room so that the indoor temperature is equal to or slightly higher than the outdoor temperature. ?

second, try to isolate the invasion of warm and humid air. We should pay close attention to the weather changes. Once the wind turns from north to south, we should close the doors and windows in time, and the doors of indoor wardrobes and kitchen cabinets should also be closed to reduce the entry of warm and humid outdoor air.

Third, put some moisture-absorbing substances indoors. It is more economical and ideal to use quicklime (massive lime). When lime melts, it should absorb water vapor in the air and release heat, which has a warming effect on the room.
