The weather is from 1 to 6.

"1 ~ 6, the rain and heavy rain lasted for 6 days, and I cried after it was cold to Qingming." The agricultural proverb is: It snows continuously in Qingming Festival, and it frosts in Grain Rain.

Qingming is one of the twenty-four solar terms and the fifth solar term in spring. It will clear up when the sun reaches 15. Tomb-Sweeping Day was named after "The Riverside Scene at Qingming Festival shows everything".

Qingming is a solar term that reflects the phenological changes in nature. At this time, the sun is shining, plants are sprouting, flowers are in full bloom, and nature presents a vibrant scene. In the south of China, it has become a clear and beautiful image at this time; It began to snow in the north, the temperature rose, and spring blossomed.

Qingming usually changes from April 4 to 6 in the Gregorian calendar, and it is not fixed on a certain day, but April 5 is the most common. Tomb-Sweeping Day is both a solar term and a festival, and Tomb-Sweeping Day atmosphere provides important conditions for the formation of Tomb-Sweeping Day customs in terms of time and weather phenology.

In the northern region, the snow began to fall and gradually entered the sunny spring; At this time, the temperature in the northern region rises rapidly, precipitation is scarce, and it is dry and windy, which is the time of dusty weather in a year. The weather here seems to be two different days in the north and south. The north is dry and rainy, and the south is wet and rainy.

During the Qingming period, the rainfall in the middle and lower reaches of the Yangtze River in China increased significantly. Except for the eastern coast, the average rainfall in most areas of the south of the Yangtze River was above 100 mm in April. Due to its geographical location to the south and close to the ocean, South China began to experience heavy rainfall when it was affected by the front formed by the intersection of cold and warm air. The north is dry with little rain, and the average daily temperature in most parts of the north has risen above 12℃ except the northeast and northwest areas.
