Extended data

Climatic characteristics of long summer;

(1), solar term temperature

Astronomically, long summer bid farewell to spring, which is the beginning of summer. According to the standard of climatology, summer begins when the average temperature of that day rises above 22℃. Before and after the "Long Summer", only the area south of Fuzhou-Nanling Line really entered the summer in China, while some areas in the northeast and northwest just entered the spring at this time, and the average temperature in most parts of the country was around 18-20℃.

In the long summer, the temperature in the north and south of China is very different, and fluctuates frequently in the same area. The temperature in other parts of South China is around 20℃, while the low-altitude valleys feel the heat in summer as early as mid-April, and the temperature in long summer reaches above 24℃.

(2) Characteristics of rainwater

After the long summer, Jiangnan officially entered the rainy season, and the rainfall and rainy days increased significantly. Continuous rainy days not only caused wet damage to crops, but also caused the prevalence of many diseases.

Before and after the long summer, the temperature in North China and Northwest China rose rapidly, but the precipitation was still not much. In addition, the wind is strong and evaporation is strong in spring. Atmospheric dryness and soil drought often seriously affect the normal growth of crops.

After the long summer, it is the key period for planting early rice in a large area, and the arrival and amount of rain during this period are closely related to the future harvest. The farmer's proverb says well: "If it doesn't last long in summer, the plow will hang high." "There is no rain in the long summer, and there is no rice in the head." There is also a folk custom of weighing and fearing the heat in summer. Jiangxi also has the custom of drinking tea in long summer, saying that if you don't drink long summer tea, you will feel uncomfortable all summer.
