When will Huangmeitian end?

From the middle and late June to the first half of July every year.

Meiyu is in the middle and lower reaches of the Yangtze River in China, Taiwan Province Province, south-central Japan and south Korea. Every June and July, there will be a climate phenomenon of continuous rainy days. Because it is the mature period of plums in Jiangnan, it is called "Meiyu", and this period is called Meiyu season.

In early summer, there are often long rainy days in the Jianghuai basin. At this time, the utensils are easy to be moldy, so it is also called "moldy rain" or "mildew" for short; It is also called "Plum Rain" or "Huang Meiyu" because plums in the south of the Yangtze River are yellow and ripe. After mid-June, the rain belt remained in the Jianghuai basin, which is Meiyu.

There are many proverbs that use winter weather characteristics to predict plum rains. For example, "there is more snow in the twelfth lunar month, and the water is yellow and the plum blossoms are fragrant", which means that the snow in the twelfth lunar month is positively related to the plum rains.

"Cold water is dry, so is summer water", and "dry" means less rain. When there is less rain in winter, there is less plum rain. This is because the weather often has stages. Persistent drought is often caused by the relative stability of a weather situation conducive to drought. However, due to the constant movement of the atmosphere, the above-mentioned relatively stable state will always be destroyed and will turn to the opposite side under certain conditions.

"Spring water overflows and summer water dries up", and "flooding" means that there is more rain than normal. As the saying goes, if there is more rain in spring, there will be less plum rain in summer, which is easy to dry. Like "peach blossoms must be dried plum blossoms", spring rains are used to predict plum rains.

"Where there is spring breeze, there must be summer rain". Spring breeze refers to the east wind (mostly southeast wind), and summer rain refers to plum rain. The proverb means that when there is a lot of easterly wind in spring, there is usually a lot of plum rain in summer.
