What is plum blossom?

Plum blossom, also called plum blossom break, refers to the end date of rainy weather in the middle and lower reaches of the Yangtze River in early summer. During the Meiyu period, the Meiyu front system and the main rain belt obviously moved out of the middle and lower reaches of the Yangtze River. The rainy days in the whole region are less than 2 days, and the maximum temperature of each station in the whole region has obviously risen above 30℃, and the surface southerly wind speed has obviously accelerated. In other words, plum blossom will occur between July 8th and 19. In some years, the plum blossom period will be postponed. After the plum rain, most areas will enter the hot summer season.

The determination of plum blossom season is based on habits and calculated by the date of dry branches. Plum blossom is the penultimate day of summer, and it is the ground branch of the main branch. Therefore, in order to calculate the date of plum, we must first find out the dates of mango and Xiaoshu, and then we can guess.

The ridge line of subtropical high jumped northward to 26. The northern latitude has been stable for more than 3 days, and the last precipitation process controlled by the periphery of the subtropical high has ended for more than 2 days.

The division of plum blossoms should not only pay attention to the seasonal variation characteristics of atmospheric circulation, but also consider the accompanying large-scale precipitation phenomenon and temperature and humidity characteristics to determine the time and place of plum blossoms.
