What does this mean? About its explanation.

1, the summer heat is a little hot, not very hot. It means that the weather is getting hot, but it is not the hottest, which means the official start of the last month of summer.

2. Little summer is the eleventh solar term in the twenty-four solar terms of the lunar calendar and the fifth solar term in summer. When the sun reaches longitude 105 degrees, it is called the summer solar term. Although it is not the hottest season in a year, it is followed by the hottest season in a year. There is a folk saying that "it is a little summer and a big summer, and it is cooked and eaten". Because of sweating, exhaustion and fatigue, people can't ignore the maintenance of their bodies.

3. The rainy season in summer is coming to an end, and the temperature rises in midsummer and enters 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. Signs of slight summer heat: plum blossoms fall.

4. Since long summer, the plum rains in the Jianghuai basin have ended one after another, and the southeast monsoon rainy season from the Pacific Ocean has begun in the vast areas north of the Huaihe River and east of the Qinling Mountains, with an obvious increase in precipitation and relatively concentrated rainfall; South China, Southwest China and Qinghai-Tibet Plateau are also in the southwest monsoon rainy season from the Indian Ocean and the South China Sea. The middle and lower reaches of the Yangtze River are generally hot and rainy under the control of subtropical high.
