Meteorological changes in Qingming:

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, the air is fresh, everything is alive, and nature presents a vibrant scene.

In the south of China, the climate is fresh and warm, and the land is beautiful in spring. 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 April in most areas of the south of the Yangtze River is above 100 mm.

Due to its geographical location to the south and close to the ocean, heavy rainfall began to appear in South China 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.
