When is the rainy season (when is the rainy season every year)

In rainy season, the ground is wet, the temperature rises, and clothes and furniture are prone to mildew, so it is also called "mildew rain". Many people always want to take preventive measures before entering rainy weather to prevent the furniture and appliances at home from getting wet. So when is the rainy season?

Meiyu time in various regions

Although Meiyu is a unique weather and climate in the middle and lower reaches of the Yangtze River, its appearance is not isolated, but closely related to the north-south displacement of a large-scale rain belt.

From mid-May to early June, in the east of China, the main rain belt swings in Nanling Mountains and the area south of Nanling. After mid-June, the area south of Nanling has been outside the rain belt, and the rainy weather has ended.

In the middle and late June, the main rain belt moved northward within the range of 29° n-33° n, with little movement.

From mid-June, the middle and lower reaches of the Yangtze River in China bid farewell to the sunny early summer and ushered in the rainy season. Heavy rain and torrential rain appeared from time to time until the beginning of July. This is the famous rainy season in the middle and lower reaches of the Yangtze River.

What is plum rain?

In the south of China, the popular proverb "Rain hits Huangmei's head and there is no sun for forty-five days" is the main feature of rainy season. So what is the rainy season?

The stay time of rain belt in early summer is called "Meiyu season", the day when Meiyu season begins is called "entering plum blossom", and the day when it ends is called "emerging plum blossom". In the rainy season, things are easy to get moldy, so it is called "moldy rain". In rainy season, plums are yellow and ripe, so it is also called "Huang Meiyu". In the rainy season, there will often be gloomy and rainy weather that lasts for a long time, and the air is filled with fine and continuous broken rain.

The formation of plum rain

Every year from late May to early June, cold air from the north and warm air from the south meet in South China, forming a quasi-stationary peak in South China. Because there is a lot of water vapor in the warm air from the south, when it meets the cold beriberi mass, it will produce a lot of convection activities. Because the strength of cold and warm air is equal during this period, the front stays in the Jianghuai area, forming continuous rainy weather.

The area where plum rains occur.

Meiyu mainly occurs in the middle and lower reaches of the Yangtze River in China and the southernmost part of Taiwan Province Province, Liaodong Peninsula, Korean Peninsula and south-central Japan in the subtropical monsoon climate zone. There is no plum rain in other parts of the world at the same latitude. There is no obvious plum rain in South China.

Precautions in rainy season

Pay attention to moisture

Meiyu is a high incidence of rheumatic pain. According to relevant data, the number of rheumatic patients in the rainy areas in the south is obviously higher than that in the arid north. Therefore, in order to prevent wet evil from taking advantage of it, a dehumidifier should be prepared at home during the rainy season, and some lime can be sprinkled in the corner. When decorating the floor, you should spread a moisture-proof film and try not to stay in a damp place.

pay attention to the diet

Eat more foods that strengthen the spleen and eliminate dampness. Lentils, coix seed and wax gourd all have the effects of invigorating spleen and eliminating dampness, so you should eat more in rainy season.

Eat less wet and cold food, such as cold drinks, habits, pears, etc.

Pay attention to your daily life.

Arrange exercise reasonably, strengthen physical exercise and enhance immunity. Arrange your schedule reasonably, and don't stay up late.
