China Weather Network News Today (February 4), we ushered in the first solar term of the 24 solar terms - the beginning of spring. When I was a child, the impression of solar terms was left from the proverbs in the mouths of adults, "After eating the beginning of spring rice, the day is warm", "When the rain arrives in the beginning of spring, get up early and go to bed late", "The beginning of spring is clear, and the rain is even", ......Have you heard these proverbs today? Is it really a warm day at the beginning of spring? Why do you have to get up early and go to bed late at the beginning of spring?
Our country regards the beginning of spring as the beginning of spring, the most important thing on this day is to "bite spring", eat spring cakes in the north, eat spring rolls in the south, and have the custom of biting radishes in ancient times, in short, to eat a meal with special significance, in order to show respect for spring. After eating the beginning of the spring meal, people can feel that the day is warmer, and the breath of spring is getting stronger day by day.
Is it really a warm day to enter the beginning of spring? China Weather Network statistics on the change of average temperature in China during the beginning of spring all year round, the national average temperature on the first day of the beginning of spring is only -326, and on the last day of the beginning of spring, it rose to -104, up 2 in 15 days22℃。During this period, although there are still small fluctuations, the overall trend is indeed gradually warming.
It is also warming, but the pace of the north and south is not very consistent. According to the statistics of the average temperature of provincial capital cities during the beginning of spring, China Weather Network found that the cities with large temperature increases are mainly concentrated in the north. Like Harbin in the northeast, the average temperature can rise by 3 during the beginning of spring all year round7, Beijing in North China, the warming range is 21, while the temperature rise in Guangzhou in southern China is only 12℃。
Why is the temperature rise in the north greater than in the south at this time? Zhang Juan, a meteorological analyst at China Weather Network, explained that the basic temperature in the north is low in winter, so there is more room for warming. In the south, the base temperature is relatively high and the humidity is greater, so the temperature rises to a lesser extent. However, even if the northern cities warm up significantly, the temperature is still much lower than in the south, and it will take a long time to enter the meteorological sense of spring.
In ancient times, people often used the weather on the day of the beginning of spring to ** the weather climate of the whole spring, or even the next year. Like "the beginning of spring is clear, the rain is even", which means that if the weather is sunny on the day of the beginning of spring, it means that the rain is balanced throughout the year. "The beginning of spring snow hydration is a zhang, and the wheat that is beaten has nowhere to be put", it is said that if the snow water in the field on the day of the beginning of spring is a zhang deep, then the wheat of the year will be harvested, "snow hydration is a zhang" indicates that the weather is good and the temperature is high, and there is a lot of snow before, this kind of rain and heat weather is indeed conducive to the growth of winter wheat. Of course, if the heat is too hot, it is not a good phenomenon, such as "the beginning of spring is too hot, turning cold and snowy", which means that if the beginning of spring is too warm, it is likely to suddenly turn cold, and then it will start to snow again, this proverb also tells everyone that after the beginning of spring, you should be careful of the cold of spring.
The proverb of the solar term is the experience summed up by the working people in long-term practice, and people are accustomed to arranging various production activities according to the experience of the proverb. At the beginning of spring, when the land thaws, the proverb at this time not only pays attention to the weather, but also reminds people to shift from the slack to the busy season. For example, "the beginning of spring at the end of the year, planting early calculation", "the beginning of spring rain, get up early and go to bed late", and we are most familiar with "the plan of the year lies in spring", all emphasize the important position of spring in the four seasons of the year, and the plan of the year will be implemented at this time.
Reciting the proverb of the beginning of spring, a new round of four o'clock replacement officially began. On the day of the beginning of spring, people eat spring cakes and hunt spring cattle to prepare for spring and accumulate energy for the upcoming farming. Generations of word of mouth have made the Chinese believe that planting a grain of millet in spring will harvest 10,000 seeds in autumn. The new year begins, and I hope that each of us will not miss the agricultural time and live up to the spring. (Curated by Feng Wei, designed by Zhang Li, and supported by Zhang Juan).
