Shanghai time enters Mei 2023.
The time of plum blossom in Shanghai in 2023: July 10 or so. The typical plum rain in Shanghai generally "blooms" from early June to mid-June, and blooms from early July to mid-July. Meiyu refers to the rainy days before plum blossom, which generally starts in mid-May and lasts for about half a month. Plum entry: the average temperature exceeds 22℃ for five consecutive days, and it rains for four consecutive days, which is regarded as plum entry and plum exit. On the contrary, if the temperature exceeds 30℃ and it doesn't rain for five consecutive days, it means that the plum leaves.
Meiyu season rainfall is relatively large, generally more than 200mm, and it is often continuous and lasts for a long time. Meiyu season is also the peak of typhoon activity, and typhoons often affect the climate and weather conditions in Shanghai. Although the rainy season makes the soil moist, it will also cause the breeding and spread of crop diseases and insect pests, which will seriously affect agricultural production. At the same time, long-term rainfall will cause soil erosion, rice lodging and other problems, leading to crop yield reduction or death.
Precautions in rainy season:
In the rainy season, the air humidity is high and the temperature is high, so clothes are easy to get moldy, so some people call the rainy season "moldy rain". After the rainy season, the weather began to be dominated by the Pacific subtropical high and officially entered the hot summer.
Therefore, clothes should be washed and changed frequently in rainy days, and it is best to choose cloth clothes that are easy to dry and smooth. In an air-conditioned room, wear a sleeveless coat, shoulder pad and trousers to cover your knees, so that vulnerable parts such as joints can be protected. Even if it is hot, remember to put a small blanket and a thin quilt when you sleep at night to avoid catching cold.
On rainy days, if there is too much moisture in the clothes in the closet and the air is not circulating, mold can easily multiply. Therefore, the clothes and quilts stored should not only be washed in advance, but also thoroughly dried before being put into the cabinet. Besides moth balls, mildewproof cakes and other commonly used mildewproof products, there are moisture-absorbing and dehumidifying products such as bamboo charcoal and charcoal products in supermarkets, which can reduce the humidity in wardrobes and shoes.
