According to the news released by Yangzhou Meteorological Bureau, in 2023, Yangzhou will enter Meiyu ahead of schedule, and it is expected that Meiyu will enter in June 10, and the precipitation will be significantly enhanced in June 12.

Plum rain, also known as "entering the mold" and "entering the plum blossom", refers to the day when the plum blossom period begins. Meteorological Meiyu refers to a rainy weather that transits from early summer to midsummer. Enter the meiyu period. Different climate seasons and plum blossom periods vary from place to place. We can't rely on the plum blossoms on the calendar to guide production and life, but to listen to the plum rain forecast released by the meteorological observatory.

In Jiangnan area, the mature period of plums in late spring and early summer is called Huangmei season. During this period, it was rainy in the middle and lower reaches of the Yangtze River in China, and the rain in this period was called Huang Meiyu. Because of the continuous rain and humid air, clothes are easy to get moldy, and Huang Meiyu is also known as mildew rain. The start date of Huangmeitian is called "entering Mei".

Calculation basis of plum rain season

According to the principle of combining circulation conditions with regional precipitation, during the period from late May to the first half of July, the ground peak activity is frequent within the range of 29-33 north latitude, with six rainy days for two consecutive weeks. At the same time, referring to the lower reaches of the Yangtze River, the average temperature of each station is basically stable above 22℃, which is the start date of entering Mei. In the time curve of rainy days, rainfall, cloud cover and other climatic factors in early summer, there are also days that suddenly increase (that is, there is a turning point), which is regarded as the average plum blossom period.

Traditionally, in China, the judgment of plum entry and plum exit is based on the combination of solar terms and branches. According to the calendar, the first third day after mango seeds is plum blossom, and the first last day in Xia Hou is plum blossom. If the weather on the awning day is C, it is designated as entering the plum blossom, and if it is not in the shallow summer, it is designated as leaving the plum blossom.

In ancient China, there were several rules for entering Mei. In trivial records, "(Min people) entered Mei on Geng Day in Xia Hou." "Shenshu Jing": "After the awn is planted, it will enter the plum in three days." "Jiangnan Record": "Plant mangoes in May, and meet your wife and enter Mei." "Tian Wu Jia Xing": "The rain after the awn seed is Huang Meiyu", and the awn seed is considered as plum blossom.

There are two reasons for the above differences: first, regional differences; Second, the date of entering Mei for many years often changes. According to Shen, in weather analysis and forecast, it often refers to the day when the weather situation turns rainy.
