Characteristics of 24 solar terms and Mild Summer.

"Twenty-four solar terms": "June Festival" ... It is also hot in summer, and it is small at the beginning of the month, big in the month, and still small today. "Summer heat" means hot, 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.

1. Thunderstorms in South China and High Temperature and Summer Drought in South China

Around the summer heat, most of southern China entered the season with the most thunderstorms. Thunderstorm is a disastrous weather phenomenon, often accompanied by strong winds, heavy rain and sometimes hail, which is easy to cause disasters. In the eastern part of South China, because it is often controlled by subtropical high, it is often sunny and hot, and after experiencing a slight summer heat, it begins to enter the summer drought period. Climatic characteristics of drought in the east and waterlogging in the west in most parts of southern China.

Second, the precipitation in Huaihe River and Qinling Mountains increased.

Since the beginning of 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. The precipitation has increased significantly and the rainfall is relatively concentrated. 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.

Third, thunderstorms are frequent in the middle and lower reaches of the Yangtze River.

The middle and lower reaches of the Yangtze River are generally hot and rainy under the control of subtropical high. In some years, the cold air force in the north is still strong before and after the slight summer heat, and it is evenly matched with the warm air in the south in the middle and lower reaches of the Yangtze River, leading to frontal thunderstorms. Thundershowers in summer are often the weather information of "yellow plum falling", which indicates that the rain belt will stay in the middle and lower reaches of the Yangtze River for some time.

Trees are shady and summer is hot. The average temperature in southern China is around 26℃ in light summer, which is already midsummer and quite hot, but it has not yet reached the hottest time. In mid-July, in the low-altitude valley area of southeastern South China, the concentration period of daily average temperature above 30℃ and daily maximum temperature above 35℃ can begin to appear.
