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 8th-12. In some years, the plum blossom period will be postponed, for example, 1954 will be postponed 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 the rainy weather from early summer to midsummer. Enter the meiyu period. The flowering period of plum blossoms is different with different climatic seasons in different places. We can't guide our production and life by the arrival and departure of plum blossoms on the calendar, but we should listen to the plum rain forecast released by the Meteorological Observatory.

Extended data: the discrepancy of plum in meteorology is different from that in almanac. In meteorology, the division of plum blossom into plum blossom, plum blossom out and plum rain period is based on the weather circulation situation of Dafan. Geographical distribution characteristics of weather system, geographical distribution position of precipitation and changes of meteorological elements.

Because the evolution of circulation situation is inconsistent 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 of stagnant or wandering rain belt is called Meiyu period; When the rain belt rises northward and reaches the Yellow River basin stably, and the Jianghuai area is controlled by the western Pacific subtropical high, the plum rains in the Jianghuai area end, that is, plum blossoms bloom.
