Meiyu Proverbs in Meiyu Season

There are many folk proverbs related to Meiyu in the middle and lower reaches of the Yangtze River in China, and we have collected some of them for readers.

There is no heavy rain in Huangmei. Sanjiu refers to the solar calendar 65438+10.9-17, and Huangmei refers to the solar term (June 6 -20). This proverb means that if there is no east wind during the third nine-year plan period, or there is little east wind, the solar term rainfall of mango will be less. The first day of March 9 is about 150 days from the first day of the solar term of mango. According to the rhythm of 150 days, there will be a similar repeating process every 150 days. Therefore, there is a corresponding relationship between the easterly wind and the precipitation of mango solar terms.

There are many proverbs that use winter weather characteristics to predict plum rains. For example, there is a lot of snow in the twelfth lunar month, and the water is yellow and plum red, which shows that there is a positive correlation between the snow in the twelfth lunar month and the plum rain.

Cold water is dry, summer water is dry, and dry means less rain. As the saying goes, if there is less rain in winter, there will be less plum rain. This is because the weather often has stages. Persistent drought is often caused by the relative stability of a weather situation conducive to drought. However, due to the constant movement of the atmosphere, the above-mentioned relatively stable state will always be destroyed and will turn to the opposite side under certain conditions.

When the peach blossoms run out, they must be dried plums. Peach blossom water refers to the Tomb-Sweeping Day air or precipitation when the peach blossoms open in April. Dry Huangmei means that mango has less rainy season or the rainy season starts later. In the lower reaches of the Yangtze River, if there is more rain in Tomb-Sweeping Day or peach blossom period in April, which is commonly known as "peach blossoms are exhausted", the rainy season of mango will be less, or the rainy season will start later. Peach blossoms fall in the mud and wheat beats in the dust; Peach blossoms fall in the dust and wheat hits in the mud, which is similar to this meaning. Too much peach blossom water often indicates that the Pacific subtropical high is stronger than normal in spring, and the warm and humid airflow is active. In the atmosphere of Tomb-Sweeping Day where peach blossoms are open, cold air from north to south often meets and confronts in Jiangnan and Shanghai, resulting in too much peach blossoms. In June, during the solar term, the subtropical high forces tend to update relatively weakly, or jump slowly to the north, resulting in less plum rains or a late start, which leads to an inverse correlation between the rainfall in these two periods.

More water in spring and dry water in summer mean more rain than usual. As the saying goes, if there is more rain in spring, there will be less plum rain in summer, which is easy to dry. It uses spring rain to predict plum rain, just like peach blossom water, it must be dried plum blossoms.

If you walk in the spring breeze, there will be rain in summer. Spring breeze refers to the east wind (mostly southeast wind), and summer rain refers to plum rain. The proverb means that when there is a lot of easterly wind in spring, there is usually a lot of plum rain in summer.

Xiaoman is dissatisfied, regardless of Huangmei, indicating that Xiaoman has a positive correlation with mango solar terms, that is, Xiaoman solar terms are less rainy, indicating that mango solar terms are less rainy, or Huangmei is late. This is because the Xiaoman solar term is the turn of spring and summer. If there is less rain during this period, it reflects that the subtropical high is weak and located in the south. In the solar terms of the canopy, the subtropical high generally does not increase rapidly. Even if there is a certain intensity, the southwest airflow at its northern edge will not extend to the lower reaches of the Yangtze River, so there will be less rainfall in the lower reaches of the Yangtze River. In the lower reaches of the Yangtze River, the precipitation of Xiaoman solar term is also called dried Huangmei, the precipitation of Mang solar term is called positive Huangmei, and the precipitation of summer solstice solar term is called sweet Huangmei. Therefore, it is called Huangmei, regardless of the lack of rain or the late start of plum rain (the solar term does not start until the summer solstice).

These people's experience of seeing the sky is verified by local meteorological data, and the accuracy rate is 70% to 80%. In other words, if it is predicted ten times, it will be correct seven or eight times. This shows that the proverb about plum rain is credible.
