[2026 无锡市惠山区期末]Have you ever experienced hui nan tian, or lasting humid weather?
Hui nan tian is a special weather condition in southern China. It normally appears in spring when the temperature begins to rise and the humidity quickly increases. Before it arrives, there are usually a few cold days, with a temperature below 12 °C. As the cold air goes away, warmer air quickly comes and the temperature rises, creating a lot of water vapour(水蒸气). Small water drops can be seen on windows and walls. For example, if the temperature is below 12 °C from March 7th to 9th but suddenly rises on March 10th, hui nan tian will appear on March 10th.
During hui nan tian, the humid weather makes it easy for bacteria(细菌) to grow. Food goes bad easily, clothes stay wet and sofas can get mouldy. Things like televisions may break down when they get wet inside, which can be dangerous for people to turn them on. It can also make people feel tired and sick. Catching a cold is very common during this time, as the temperature changes quickly. Although the weather troubles people a lot, for nature, it can be helpful. Thanks to the humid weather, plants can grow better with enough water and warmer air.
To cut down on the trouble caused by the lasting humid weather, scientists suggest that people in the south should close their windows in the morning and evening. At the same time, they should use an air conditioner to take away water from the air. It's also useful to put newspapers on the floor, on the tables and at the door to take in water and wet air.
