In winter, after a cold air warms up, many small drops of water will condense on the floor of the house, which should be wiped several times a day. My family lives on the third floor, and no one lives on the second floor downstairs. This is caused by the resurgence weather, in fact, it is caused by too many warm and humid air currents in the weather system. Just before the cold air left, the surface temperature was still low. At this time, hot and cold collision is easy to produce water vapor, and the amount of water vapor condensation in the air is large, which can also form "fog".

The duration of moist weather is related to the ground temperature and the intensity of warm and humid air flow. If cold air strikes frequently, the warm and humid airflow continues to be strong, and the resurgence weather will not fade immediately. Due to the counterattack of warm and humid air, the ground "sweated". With the weakening of cold air, the temperature gradually rises, and the warm and humid airflow continuously transports water vapor into the air, and the relative humidity will increase, resulting in "long hair" on the door panel and "sweating" on the ground.

Because of the strong cold air, the temperature dropped sharply; In addition, the air over the city is warmer, and the intersection of cold and warm air leads to cold and humid weather. After the cold air weakened, the warm and humid air quickly counterattacked and the temperature rose sharply. The water vapor in the air keeps pouring in, and a lot of warm and humid air condenses into fog, which is closely related to the lack of sunshine. There is more sunshine, water evaporates faster, and fog spreads easily. In that case, the water droplets in the house will disappear quickly.

In this case, you can put some hygroscopic substances indoors, use a dehumidifier or turn on the air conditioner. Water with a small amount of white vinegar or lemon juice is a natural mildew remover. It is effective to scrub cookware and wardrobe with a sponge. Potted soil and basin bottom are often places where molds are easy to hide, so it is best not to move indoors this season.

The moisture on the first floor is the heaviest, so the ground moisture regain is the most serious. You are better on the third floor. When cold air strikes, it is best to close the doors and windows facing south or southeast (that is, against the wind) and only open the doors and windows in the downwind direction to reduce water vapor from entering the room. When the weather clears up, doors and windows should be opened in time, and furniture placed in sheltered places should be moved appropriately to facilitate air circulation and accelerate water vapor evaporation. Secondly, some quicklime can be wrapped in cloth or sacks and placed under the bed, cabinet, desk and chair or corner to reduce indoor humidity by using the water absorption performance of lime. You can also use a number of red bricks and barbecue them next to the stove, and evenly put them on the ground to absorb some water. For common furniture such as tables and chairs, coffee tables, and daily necessities such as oil drums, salt bowls, and sugar cans, please wipe them with lukewarm soapy water once to remove oil stains, mildew spots, and dust attached to the surface, keep them clean and dry, and reduce moisture regain.

It is best not to bring wet clothes, umbrellas, shoes and socks indoors in rainy or foggy days. Wipe and clean the room frequently, pile up less sundries and keep the room clean and tidy. This can greatly reduce the moisture regain and keep the room dry.
