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. Meiyu and rainy belt Meiyu is usually the rainy season from mid-June to early July in the middle and lower reaches of the Yangtze River in China.

It is recorded in China's almanac that there is mildew rain all day: it is called "mildew" at the beginning and "mildew" all day long. The first day after the awn is planted, it is moldy, but it is not moldy on the first day after the hot summer.

Plum entering refers to the beginning of the rainy season, and plum leaving refers to the end of the rainy season. Generally, plum blossom begins from the seeds of awn, begins on the first day of C, and ends on the first day of summer. The calculation is based on the date of the main branch. Therefore, if you want to calculate the date of plum blossom and plum blossom, you must first find out the date of mango and small tree, and then you can guess.

Meiyu refers to the weather and climate phenomenon that occurs in a certain area and a certain season. Meiyu is a unique weather and climate phenomenon in East Asia and the middle and lower reaches of the Yangtze River in China.

Meiyu front rainstorm is a special weather in a specific area formed by the interaction of circulation systems of different scales. The variability of atmospheric circulation leads to the late start and short duration of meiyu period every year. In some years, the Meiyu front is particularly active, with frequent rainstorms, leading to flooding.

The standard for entering plum is that the average temperature exceeds 22℃ for five consecutive days, and four days are considered rainy. The standard of plum blossom is that the temperature exceeds 30℃ for five consecutive days, and there is no rain, which means it has officially blossomed.

In the south, May 6-15 is the day of plum blossom, and July 8-19 is the day of plum blossom. There is an obvious rainy season in eastern China, with a long rainy season and relatively concentrated rainfall. Generally speaking, the higher the latitude, the later the meiyu begins.

In the middle and lower reaches of the Yangtze River in China, plum blossoms enter in mid-June and come out in early July on average. But there are some differences in specific places. In Zhejiang, plum blossoms enter the plum blossom in May of the lunar calendar. Specifically, plum blossoms enter the plum blossom in the morning after the awning, and they rise on the solstice of summer.
