In winter in the south, sometimes the house is wet, the household appliances have no water, the walls are wet and the floor is wet. How's the weather?

It's going back to the south. . . . Some precautions. . . Pay attention

Reason: It is the phenomenon of weather resurgence, which generally appears in February and March in spring. After the cold air left, the warm and humid air quickly counterattacked, resulting in an increase in temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow. Leading to the phenomenon of "water accumulation" in furniture, floor and glass. Generally speaking, the formation of returning to Nantian requires two conditions:

1. Long-term low temperature occurs, and the daily average weather is lower than 12℃ for at least 3 days. For example, before returning to Nantian in February of 20 10, the daily average temperature was lower than 12℃ for 9 consecutive days.

2. The weather changes suddenly, and it will suddenly become warm and wet after a long period of low temperature. Back in the southern sky, the humidity is sometimes as high as 100%.

Note: Don't open the south window on a sunny day at noon. Close the doors and windows in advance to prevent the warm and humid air from entering the outdoor. Some people think that it's sunny at noon, so you can open the window for ventilation, but it can't alleviate the humidity. The outdoor temperature is the highest at noon, and the temperature difference between indoor and outdoor is also the largest. At this time, ventilation sometimes leads to more serious condensation of water vapor on indoor floors and walls.

Keep bathroom door at hand to prevent water vapor from spreading to other parts of the room. After cooking or taking a bath, remember to bring the kitchen door and bathroom door, turn on the exhaust fan, and reduce the water entering the living room.
