According to the agricultural proverb of solar terms, "a thunder in the summer heat makes a yellow plum."
is the solar term of light summer heat. The temperature rises further, and the plum rain season in Jianghuai area is generally coming to an end. However, there is a folk meteorological proverb at this time called "a thunder in light summer heat turns into a yellow plum". What does this mean? Will Mei make a comeback? Come and have a look.

"Xiaoshu thunders and turns upside down into Huangmei". This is a weather proverb widely spread in the middle and lower reaches of the Yangtze River. It means that after Mei Yu has passed, if there is thunder in the summer solar term, Mei Yu will turn back, which is the so-called "inverted yellow plum".and
inverted yellow plum refer to some years. In the middle and lower reaches of the Yangtze River, it has been several days since plum blossom came out into midsummer. The yellow plum day seems to have passed. The weather has cleared up and the temperature has increased. The meteorology in the middle and lower reaches of the Yangtze River has the characteristics of midsummer. However, a few days later, the muggy and humid thunderstorm and shower weather with the characteristics of plum rain reappeared, and the weather phenomenon remained for a considerable period of time. This situation is like Huangmei day turning back and returning to the middle and lower reaches of the Yangtze River, so it is called "pouring Huangmei". In normal years ofand
, the plum rain should have ended before the slight summer heat. In the middle and lower reaches of the Yangtze River, the plum blossom usually rises from July 8 to 12, and then enters the midsummer dry season. At this time, the rain belt should move to the north. However, in some years, the cold air force was strong and kept going south, which made the cold and warm air confront again in the middle and lower reaches of the Yangtze River, and even made the rain belt move again to the Jianghuai area before and after the slight summer heat to form precipitation. There continued to be a period of cloudy and rainy plum rain, just like the plum rain season came back again.and
but "pouring yellow plum" will not last too long. Generally, the shorter one is about a week, and the older one is ten days and a half months. And it should be noted that "a thunder in the heat" is not the reason for "pouring yellow plum", but only a possible weather phenomenon. It must be pointed out that the occurrence of Meiyu anomaly is not an isolated weather and climate phenomenon in the middle and lower reaches of the Yangtze River. Some serious years are also associated with the anomaly of atmospheric activities in the whole northern hemisphere and even around the world. The anomaly of global atmospheric movement is closely related to the abnormal change of seawater temperature (such as El Nino phenomenon and La Nina phenomenon), global volcanic activity, sunspot activity and so on.and
