In June and July every year, there will be continuous rainy weather in the Jianghuai area of the mainland, at this time it is the time when the plum in the south of the Yangtze River is ripe, so it is called "plum rain", during the plum rain due to the high air humidity, the utensils are easy to mold, so people are also called "plum rain". Every year, on the first day of the rainy season, we call it "Izume", and every year on the day after the rainy season ends, we call it "Izume".
When will it be "out of the plum" in 2024?
"Out of the plum" means that the rainy days are over, the rainy days are heavy and rainy, and with the northward movement of the subtropical high after the "out of the plum", various places will enter the high temperature season of midsummer. There are some small ways to judge whether it is "out of the plum", if there is more than or equal to 5 days of rain in the place, and the average daily temperature is stable above 25 °C in the month, then it can basically be determined that the "out of the plum" is basically determined.
From a scientific point of view, the rainy season is caused by the movement of the subtropical high, and the northern ridge line of the subtropical high and the cold air from the north continue to meet in the Yangtze River area in June and July every year, and it is easy to form the rainy season. With the northward movement of the northern ridge line of the subtropical high, the Yangtze-Huaihe region is under the control of the subtropical high and begins to enter a period of "sub-drought", which is what we call "out of the plum", and from late July to early August, the main rainfall belt moves to North China and Northeast China. If the northern ridge line of the subtropical high continues to stabilize above 25 degrees north latitude, then it can be judged that it has "emerged".
In ancient times, there was no weather forecast, and our ancestors determined the time of "out of the plum" according to the time of the solar term and the time of the dry branch calendar, which is not as accurate as meteorology, but it is also eight or nine and ten.
According to the provisions of the ancient calendar of the mainland: "the first day after the summer is the plum", the mainland has been using the Ganzhi calendar to record its and the day order, "Weiri" is the day with the earthly branch "Wei" in the Ganzhi calendar, such as Xinwei Day, Ren Wei Day, Yi Wei Day, Ding Wei Day, Ji Wei Day.
On July 6 this year, this day is "Xinwei Day", that is, the day of Xiaoxia is "Wei Day", so this year's Xiaoxiao Festival is the time of "out of the plum". Every year, the time of the small summer festival is from July 6th to 8th, and this year's July 6th "out of the plum", can be this year is the "earliest out of the plum".
This year's "out of the plum" and Xiaoxia meet, what is the saying? Let's take a look at what the agricultural proverb says.
First, the small summer thunder, pour the yellow plum
"Pour" means "reverse", and the "poured" here refers to the fact that the rainy season has ended, the weather has cleared and the temperature has risen, but after a few days, there has been a continuous rainy weather, that is, the yellow plum day has gone back again, and the rainy day has come again, this phenomenon is called "inverted yellow plum".
The agricultural proverb says "small summer thunder, pour yellow plum", which means that if there is thunder on the day of the small summer festival, then this indicates that there will be "poured yellow plum" weather in the future.
This year, if there is thunder on the same day, it means that even if it is the time of "Mei", it does not mean that the rainy weather is over. "Poured yellow plums" generally do not last long, as short as about a week, as long as ten days and half a month, so there is a saying of "eighteen poured yellow plums" in the mainland.
Second, the rain hit the small heat, and it rained for 45 days
"Little Summer" refers to the first day of the Little Summer Festival, that is, the day of the Little Summer Festival, and this year's Little Summer Festival is on July 6. According to the experience of our ancestors, if it rains on the day of the summer festival, there will be more rain for a long time afterward.
Third, out of Meitian tears, Huangmei went back again
"Tears in the sky" refers to the rain in the sky, and this agricultural proverb means that if it rains on the day of "Izumei", then according to the experience of our ancestors, this indicates that the rainy weather of Huangmei will be reversed, that is, there will be a second "into the plum" situation.
According to the experience of our ancestors, thunder and rain on the day of Xiaoxia indicate that there will be "poured yellow plums", and the rain on the day of "plum blossoms" also indicates that there will be "poured yellow plums". If it rains on this day, then it indicates that the probability of more rain will be greatly increased in the future, and we must pay special attention to flood prevention; On the contrary, if this year's "plum blossom" day is sunny, then it indicates that there will be less rain in the future, and we must pay special attention to preventing "drought".
For farmers, too much or too little rain in the summer is not a good thing. I hope this year will be smooth and rainy, and the grains will be abundant! Do you think these agricultural proverbs are still accurate? Feel free to leave a message.
