What does the summer solar term mean?

Summer is hot. The ancients thought that the summer heat period was not the hottest time of the year, so it was called summer heat. The solar term ballad says, "Little summer is not hot, but big summer lasts for three days." It is pointed out that the hottest period of the year has arrived, but it has not reached the extreme hot level.

Slight summer heat is "slight heat", which means that although we can already feel the heat of the weather at this time, it has not reached the hottest time of the year, just the beginning of a hot summer day. As the saying goes, "the heat is at three volts." The dog days, which appear between the light summer heat and the hot summer heat, are the time when the temperature is the highest and it is humid and sultry in a year.

Monsoon climate is the main feature of China climate. Monsoon climate is a mixture of continental climate and maritime climate. Summer is affected by the warm and humid air flow from the ocean, which is hot, humid and rainy. The high temperature in monsoon climate is basically the same as that in rainy season, and the rain and heat are in the same period, which is beneficial to crop growth. In summer, the weather is hot and thunderstorms are frequent, which is the season when everything is crazy.

Phenological phenomenon of slight summer heat

Wu Cheng, a scholar in Yuan Dynasty, edited Twenty-four Solar Terms. According to the scenery around the Yellow River Basin and the characteristics of the twenty-four solar terms, he divided the twenty-four solar terms into "seventy-two periods", and each solar term was divided into three periods.

The third phase of the summer heat is: "When the wind is warm; 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."

August mentioned in this paper 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.
