What is the rainy season?

Meiyu season is a warm and humid air flow in the Pacific Ocean brought by the southeast monsoon in June and July every year, which passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea. Because it is the mature period of plums in Jiangnan, it is called "Meiyu", and this period is called Meiyu season.

Meiyu mainly occurs in the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, Liaodong Peninsula, the southernmost tip of the Korean Peninsula and the subtropical monsoon climate zone in south-central Japan. There is no plum rain in other parts of the world at the same latitude. There is no obvious plum rain in South China. Typical plum rains generally "enter plum blossoms" in the middle and late June, and bloom in early to mid-July. Meiyu refers to the rainy days before plum blossom, which generally starts in mid-April and lasts for about half a month.

In the rainy season, the air is humid and full of water vapor. One trick is to close the window at the right time, and the time of closing the window is very important. Special attention should be paid to closing the windows in the morning and evening, because these two periods are generally the time when the air humidity is the highest all day, which is much higher than noon. At this time, if the doors and windows are not closed in time, water vapor will easily penetrate into every corner of the house and accelerate the "moldy" speed. If you need to open the window for ventilation, you can choose to open the window for ventilation before noon and at 3 pm.
