What is a little summer heat?

As the weather gets hotter and hotter, the solar terms of summer heat are gradually approaching us. Let's follow the small series of the perpetual calendar to see what the summer heat is like.

On July 7th or 8th every year, when the sun reaches the longitude 105, it is called Guangxia, which is the 1 1 solar term among the 24 solar terms. Twenty-four solar terms: June Festival? Summer, summer, size, small at the beginning of the month, big in the month, and still small today. "Summer heat means heat, it is a little hot, not very hot. It means that the weather is getting hotter, but it is not the hottest, and most parts of the country are basically in line with it. At this time, the Meiyu in the Jianghuai Basin is coming to an end, and the temperature in long summer has risen and entered the summer drought period; However, when North China and Northeast China entered the rainy season, tropical cyclones were active frequently, and the number of tropical cyclones landing in China began to increase. After the summer, the south should pay attention to drought resistance and the north should pay attention to flood control. Crops all over the country have entered a vigorous growth period, and it is necessary to strengthen field management.

In ancient China, the summer heat was divided into three periods: "First, it was warm and windy; Second, wait for crickets to live in space; The third waiting eagle began to crow. " In summer, there is no cool wind on the earth, and all the winds carry heat waves; The Book of Songs? In July, the words to describe crickets are "July is in the wild, August is in the house, September is in the house, and October crickets enter my bed." The August mentioned in this article is June in the summer calendar, which is a short time in summer. Because of the heat, crickets leave the field and go to the corner of the yard to escape the heat. In this solar term, the eagle is in the cool high air movement, because the ground temperature is too high.

Slight summer heat is relative to great summer heat. The ancients thought that this was not the hottest time of the year, so it was called a slight summer heat. As the saying goes, "the heat is at three volts." In our country, the dog days generally appear on the 28th day from summer to the future, which is called "Three Geng from summer to the sun, and the number of people is falling".
