What do you mean by "out of plum blossom" and "into plum blossom"? (lunar calendar)

Plum blossom, also known as "broken plum blossom", refers to the end date of plum rain. Meiyu in Jianghuai area of China usually ends on July 8-12. In some years, the plum blossom period will be delayed, such as 1954 to August 2, and the plum rain period will last for 63 days. After the meiyu, most areas entered the high temperature season in midsummer.

Entering plum is also called "entering mildew" and "entering plum". Refers to the day when the rainy season 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.

Extended information: The meteorological plum blossoms are different from those in the almanac. Meteorologically, the division of plum blossom into plum blossom, out of plum blossom and rainy season is based on the weather circulation situation of Dafanwang. Geographical distribution characteristics of weather system, geographical distribution position of precipitation and changes of meteorological elements.

Because the evolution of circulation situation is not consistent or the same every year, there are complex differences in meteorology, plum blossom date and plum blossom period. When the Meiyu front area and its rain belt reach or form in the middle and lower reaches of the Yangtze River or the Jianghuai area, it is called Meiyu. The period when the rain belt is stagnant or wandering is called Meiyu period; When the rain belt rises northward and reaches the Yellow River basin steadily, and the Jianghuai area is controlled by the western Pacific subtropical high, the plum rain in the Jianghuai area ends, that is, plum blossoms appear.
