Will it rain during Grain Full in 2021?

The probability of rain during Grain Full in 2021 is relatively high, because Grain Full itself is a solar term reflecting precipitation, and it is in the plum rain period.
After Grain Full, the weather will gradually change from warm to hot, and the precipitation will gradually increase. There is a folk saying that "Grain Full and Big Full mean that the rivers are full." After Grain Full, the average temperature in most parts of China will be above 22℃, and the amount of rainfall will gradually increase.
During the Grain Full solar term, southern China generally experiences heavy rainfall. Due to the active warm and humid air flow in the south, it meets the cold air moving south from the north in South China at the intersection of the Yellow Sea and the obliquity. At this time, South China often experiences continuous and large-scale heavy rainfall, causing heavy rain or torrential rain, just as the folk saying goes, "During the Grain Full Season, rivers are prone to overflow." The rivers and lakes in the Jiangnan region are often full. If there is less rain during this period, it may be that the subtropical high pressure in the Pacific is weaker and located further south, which means it is the plum rain season. In the north, there is little or no rainfall during the Grain Full solar term, during which time the temperature rises rapidly, further narrowing the temperature difference with the south.

What is the meaning of the Grain Full solar term?

The Grain Full solar term has two meanings: one is related to rainfall, and the other is related to agriculture.
1. The "man" in Xiaoman refers to the ripeness of the grains. "Xiaoman, in the middle of April, means that the wheat has reached Xiaoman at this time, because it is not yet ripe."
2. The "man" in Xiaoman refers to the abundance of rainwater. "The rivers are full during the Grain Full and the Big Full." The heavy rains in the south are beginning to increase and precipitation is frequent.
"Collected Explanations of the 72 Seasonal Changes in the Lunar Calendar" describes that "In the middle of April, there is the Grain Fullness, when things are small but full." At this time, the grains of summer crops such as wheat in northern China have begun to become full but are not yet mature, which is roughly equivalent to the late milky stage, so it is called Grain Fullness. It is a solar term that indicates the changes in phenology.
