Old people often say: beginning of spring is sunny, and Mo Wen is immortal. What is the scientific basis for this statement?

Beginning of spring is one of the 24 solar terms, and beginning of spring is also the first solar term. The weather is sunny in early spring, so when the weather forecast has not been developed, it is actually an expectation of good weather. When beginning of spring comes, it means that spring has come. The arrival of beginning of spring is the beginning of spring, and the weather will gradually get warmer. Spring returns to the earth, and everything revives. In the former countryside, without the warning of the weather forecast, people would pay attention to beginning of spring, knowing that the weather would get better and better after beginning of spring. It's sunny in early spring. People don't have to ask God, it is a beautiful expectation for the weather. As soon as beginning of spring arrived, people began to prepare for sowing in spring. All kinds of crops are planted in various places, and no matter where they are, they all have the same expectation for good weather. Because good weather is of great significance to agricultural planting. If the weather is bad, the growth of crops will naturally be unfavorable, and agricultural planting will become more difficult, so people expect good weather and sunny days. There is another saying? On that day in beginning of spring, it was raining and wet until Qingming? In other words, if it rains all the time in the spring, it will last for a long time and will not stop until Qingming. Rainfall lasts for a long time, which has a great impact on agricultural planting and production! After all, it is inconvenient for people to go out to farm in rainy days, and it is troublesome and unfavorable to step on the mud. Therefore, people don't want it to rain in the spring, which is very unfavorable to agricultural production.

In the minds of farmers in the past, good weather was God's best arrangement and the blessing of the gods. They hope that good weather will bring good output and then a good harvest. Is there such a proverb among the people? It's sunny in early spring, so it's easy to plow? . So it was a sunny day in early spring, which also means that there will be a good harvest this year, and this year will be a bumper harvest year. Since beginning of spring, the temperature has risen rapidly, so if the weather is clear in early spring and the temperature rises faster, farmers can farm early. If it rains, it will be delayed, which will affect the time of planting crops and thus the harvest.

Therefore, people say that it is sunny in beginning of spring, which is actually a kind of expectation for fine weather in farmers' hearts, because they hope it will be sunny in beginning of spring, which is a beautiful expectation.
