the difference between spring and rain and rain in other seasons is that it will be accompanied by spring thunder at the same time. This phenomenon especially occurs in the period of hibernating. During this period, thunder accompanied by rain awakens hibernating animals and plants, and everything begins to sprout and grow. What are the characteristics of temperature and climate in the period of hibernating? What should we pay attention to?

reflects the awakening of natural phenological phenomena, which means that the sudden movement of spring thunder awakens the animals dormant in the soil. At this time, the temperature rose rapidly, and spring thunder has gradually appeared in most areas of the Yangtze River Basin. In the eastern part of Sichuan Basin and the southern part of Liangshan Prefecture, the spring thunder can also be heard through perennial rain and waking insects; In the northwest of the basin, except for individual years, there is generally no thunder until Qingming, which is the area where thunderstorms begin the latest in our province. When it comes to waking insects, most parts of China have entered the busy spring farming season. It's true: Seasons don't wait, a moment is worth a thousand gold. The average temperature of hibernating solar term in the basin of our province is generally 12 ℃ to 14 ℃, which is more than 3 ℃ higher than the rain solar term, which is the solar term with the fastest temperature rise in the whole year. Sunshine hours also increased significantly. However, due to the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. In the Yangtze River Valley in the southeast of the basin, the temperature is stable above 12 ℃ in most years, which is conducive to rice and corn sowing. In other areas, there are often low-temperature weather with a daily average temperature below 12 ℃ for more than three consecutive days, so it is not allowed to sow blindly early. Although the temperature rises rapidly, the increase of rainfall is limited. The total rainfall during hibernation in the central and northwest of the basin is only about 10mm. After the perennial dry winter, the spring drought often begins to emerge. At this time, wheat booting and rape flowering are in the period of more water demand, and are sensitive to water requirements. Spring drought often becomes an important factor affecting spring yield. This climatic feature should also be considered in afforestation. After planting, we should be diligent in watering and strive to improve the survival rate of seedlings. In the season of waking insects, the spring is bright and everything is renewed. Through careful observation and accumulation of phenological knowledge, it will be helpful to arrange agricultural activities according to local conditions.

the eagle turned into a dove: the eagle began to hide quietly to breed offspring, and the originally dormant dove began to sing for mate. The ancients didn't see the eagle, and the surrounding doves seemed to increase all at once, so they mistakenly thought that the eagle turned into a dove.
