Twenty -four solar terms · Bai Lu ｜ 冽 二 二 二 二 二 二 二 二

Pomegranate/Xinjiang Daily News (Reporter Yu Mengfan reported) "The autumn wind is He Yan, Bai Lu is a cream." On September 7, we ushered in the Bailu festive in the twenty -four solar terms.

Along with the arrival of Bai Lu's solar terms, the day when the temperature difference between the most temperature was also coming. We often hear "a spring rain and a warmth, one autumn rain and a cold." Whether it is spring rain or autumn rain, rainfall is formed by the convergence of warm and cold air. Why does the temperature rise after the spring rain, and the autumn rain is getting colder?

The reason is related to solar activities. In spring, the direct sunlight movement moves from south to north. The solar radiation of the northern hemisphere in our northern hemisphere gradually enhances, and the warm air advances north. In the autumn, the direct point of the sun moved from the northern hemisphere to the south hemisphere. The calories left to the northern hemisphere are not as sufficient as spring day. After the autumn rain, people's body feel is getting colder and colder.

Bai Lu has three waiting, one waiting for Hongyan, and the black bird returns. In the season of Bailu, Hong Da Yan was small, flying from north to south, and the weather gradually turned cold. The mysterious bird is a swallow. From March to May of each year, he returns from the south to the northern region from the south to find a spouse, build a nest, and reproduce. Every year from September to October, they move to the south to spend the winter. "Shame" is the same as "是", which is a food. Shame refers to the birds who perceive the killing of killing, and they have stored food to prepare for winter, such as Zang Zhen.

After the arrival of Bai Lu's solar terms, the summer wind was gradually replaced by the winter wind. The cold air went south and gradually became frequent. The strength of the sun was weakened. The origin of the statement.
