What is the meaning of light summer heat?
The light summer season is the eleventh solar term of the twenty-four solar terms in the lunar calendar and the fifth solar term in summer, which indicates the official start of the The Last Month Of Summer season. On July 7th or 8th every year, it is considered as a slight summer heat when the sun reaches the longitude of the yellow meridian105. Summer heat means hot, and a little summer heat means a little heat, which means the weather is getting hot, but it hasn't reached the hottest yet. This climate is basically consistent in most parts of China.
The average temperature in southern China is about 26℃ in light summer, which is already midsummer. All localities have also entered the season with the most thunderstorms, often accompanied by strong winds, heavy rains and sometimes hail. Most areas in the south are dry in the east and waterlogged in the west, so drought and flood control measures must be taken as early as possible to minimize the harm.
Climatic characteristics of solar terms in summer heat
Starting from July 7th or 8th of the Gregorian calendar every year, it is a slight summer heat when the sun reaches105. Literally speaking, "summer heat" means "heat", which means that the climate is hot during the summer heat. In the almanac, it is said, "Dou means Xin is a mild summer heat, and the weather in Sri Lanka is already hot and has not reached the extreme, hence the name." In other words, although the weather is very hot at this time, it is not yet the hottest time, so it is called "light summer heat".
A mild summer heat is a mild heat. In ancient China, the summer heat was divided into three periods: "One is warm and windy; Second, wait for the cricket to live in the space; The third waiting eagle begins to crow. "
In the summer, there is no longer a cool breeze on the earth, but all the winds carry heat waves; Because of the heat, the cricket left the field and went to the corner of the courtyard to escape the heat; In this solar term, the eagle moves in the cool high air because of the high temperature on the ground. In the light summer, the plum rains in the Jianghuai basin will soon end, and the temperature will rise in midsummer, and it will enter the summer drought period. However, North China and Northeast China will enter the rainy season, and tropical cyclones will be active frequently, and the number of tropical cyclones landing in China will begin to increase. In a word, the climate characteristics of the solar terms in the light summer are hot weather and increased rainfall.
