What does rainy weather mean in 2020?

Meiyu refers to a period of continuous rainy weather from mid-May to mid-June and early summer. The middle and lower reaches of the Yangtze River in China refer to the range of 28°-34° N east of Yichang, or the narrow area from Jianghuai Valley to southern Japan.

Initially, it originated from a meteorological term in China. In ancient times, Meiyu was usually called Huang Meiyu. As early as the Han Dynasty, there were many proverbs about Huang Meiyu. In the Jin Dynasty, there was already a record of "summer rain to the sun, named Huang Meiyu"; Since the Tang and Song Dynasties, there have been many interesting descriptions about Meiyu. Liu Zongyuan, a writer in the Tang Dynasty, once wrote a poem about Meiyu: "Shi Mei welcomes Meiyu, and it is already late spring. I am deeply worried about the night of the ape, and my dream has run out in the morning. The sea fog connects the South Pole, Jiang Yun dark Beijin, plain clothes today, not for the dust of the imperial city ". Among them, "Shi Mei welcomes the rain" means that when plums are ripe, they welcome the rain from summer to three o'clock in the future. At present, the meteorological plum rain refers to a rainy weather that transits from early summer to midsummer.

In addition, due to the high humidity in the air during this period, everything is easy to be damp and moldy, so people gave Meiyu an individual name, called "Moldy Rain". Ming metabolic slaughter line "Five Miscellaneous Torches One Day Department" describes: "Every year in March and April, there is bitter rain in the south of the Yangtze River, and everything is moldy and rotten, commonly known as plum rain, and plums are covered when they are green and yellow. From Xu Huai to the north, it is often dry in spring and summer. At the turn of June and July, it rained heavily and everything was moldy. " Li Shizhen, an outstanding medical scientist in Ming Dynasty, pointed out more clearly in Compendium of Materia Medica: "Plum rain or mildew rain, when it comes to clothes and things, will produce black mold." .

It can be seen that the appellation of "plum rain" or "mildew rain" has a long history, and it began to spread in China, at least dating back to 1000 years ago.
