What is the name of the last solar term in summer?
Summer is the twelfth solar term among the twenty-four solar terms and the last solar term in summer. It is usually celebrated between July 22nd and 24th in the Gregorian calendar. Summer refers to the unusually hot weather, which is the hottest period in a year, and the temperature often reaches the highest value. At the same time, the summer heat is also the solar term with the most thunderstorms, and extreme high temperature weather and frequent thunderstorms, typhoons and other disasters will occur in many areas.
Wu Cheng, a scholar in Yuan Dynasty, compiled twenty-four solar terms, which were divided into "seventy-two periods" in a year, and each solar term was divided into three periods. The third phase of the Great Summer is: "A rotten grass is a firefly; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. "
Every summer, due to high temperature and rainy weather, bacteria are easy to breed, and many dead plants are wet and corrupt. At night, fireflies can often be seen flying around, looking for food on rotten grass and leaves. In addition, the soil is hot and humid, which is very suitable for the growth of water-loving crops such as rice. The third kind of weather means that rain will fall in the sky at any time in this hot and humid weather in the same season.
Meteorological changes in summer solar terms;
The summer solar term is just before and after the Mid-Autumn Festival in the dog days, and the "hot and humid steaming" also reaches its peak at this time. The summer heat is the season with the most thunderstorms and abundant rainfall. High temperature and rainy period are basically the same, and rain and heat are the same.
China is a typical monsoon climate, which is controlled by subtropical high and other atmospheric circulation systems. From mid-June to mid-July, the main rain belt in eastern China generally extends from South China and Jiangnan to Jianghuai area. From late July to early autumn, with the seasonal northward movement of the subtropical high circulation system, the southwest monsoon will also move northward.
The southwest wind around the subtropical high transports the warm and humid airflow of tropical and subtropical regions to the northern region, where it meets the cold air of mid-latitude in North China and Northeast China, and North China and Northeast China begin to enter the rainy season. Northwest China is the arid area with the least annual precipitation in China, because it lives inland and far from the ocean.
