What season is Huangmei season?

Huangmei is actually a fruit. In ancient times, apricot was called Huangmei, and its mature season was from June to August, which was in summer, so this period of summer was also called "Huangmei season". In June and July every year, the warm and humid air flow in the Pacific brought by the southeast monsoon passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea, which is 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.

The middle and lower reaches of the Yangtze River in China are usually rainy from mid-June to early July every year. In the past few days, the sky has been gloomy and the precipitation has been constant, sometimes big and sometimes small. Therefore, there is a popular proverb in southern China: "Rain hits plum blossoms, and there is no sun for forty-five days". Continuous rain, high temperature and high humidity are the main characteristics of plum rain. Very different from the climate in the same latitude area, Meiyu refers to the weather and climate phenomenon that occurs in a certain area and a certain season.

The west coast of the mainland is controlled by the downdraft on the east side of the subtropical south pressure in summer, with sunny weather, partly cloudy and dry climate; In winter, under the influence of westerlies, warm and humid air is brought from the Atlantic Ocean, resulting in more precipitation and a mild and rainy climate. That is, the subtropical Mediterranean climate is dry in summer and humid in winter.

The law of rainy season:

The beginning date of plum rain is "entering plum" and the end date is "leaving plum". Generally speaking, the higher the latitude, the later the meiyu begins. China Taiwan Province Province will bloom in mid-May and in mid-June. In the middle and lower reaches of the Yangtze River in China, on average, the lunar calendar enters Mei in mid-April and leaves Mei in early May every year. But there are some differences in specific places. In Zhejiang, plum blossoms enter the plum blossom in the early May of the lunar calendar, specifically on the first third day after planting awns, and the first plum blossom before sunrise after the intense heat.

The plum rain range, duration and rainfall of Prunus mume vary greatly from year to year. In some places where there should be plum rain, if there is no plum rain in some years, this phenomenon is called empty plum. After the rainy season, it usually clears up and enters the hot summer. If it turns rainy again at this time and lasts for a long time, it seems that it has returned to the plum season, which is called "heavy plum". There is a folk proverb that says, "When it thunders in summer, the plum blossoms pour".
