Climatic characteristics of summer solar terms

high-temperature

Generally speaking, the summer solar term is the period with the most sunshine and the highest temperature in a year, the period with the most abundant rainfall, the most common thunderstorm and the most concentrated days with high temperature above 30℃ in western South China, and the period with the most frequent occurrence of high temperature above 35℃ in eastern South China.

The end of July to the beginning of August is the active period of the western Pacific subtropical high, which often occupies the eastern part of China. When it is strong, it can be controlled westward to the eastern part of southwest China, such as eastern Sichuan and Chongqing. Similarly, in summer, many areas of Chinese mainland are often controlled by continental high, which is also caused by subsidence and warming. Part of the cloudy and hot ground bakes the air to keep the temperature high.

Generally speaking, the number of people suffering from heatstroke increases obviously on hot days when the daily maximum temperature is higher than 35℃. When the maximum temperature is above 37℃, the number of heatstroke will increase sharply, especially in the middle and lower reaches of the Yangtze River under the control of subtropical high. The sun is like fire, the wind is small and the humidity is high, which makes people feel sultry.

Nanjing, Wuhan and Chongqing along the Yangtze River have 17 ~ 34 days of "hot days" and 3 ~ 14 days of "hot days" every year on average. In addition, in Guixi, Jiangxi, Hengyang, Hunan, Kaixian, Sichuan and other places, the average annual "high temperature day" is more than 40 days, and the whole middle and lower reaches of the Yangtze River is a big "stove".

tornado

The summer heat is also the season with the most thunderstorms. There is a proverb that says, "Without a drop of lightning in the east, the west can't walk", which means that if there is lightning in the east in summer afternoon, it won't rain here. If lightning is in the west, it will come soon, and it is too late to hide. People often refer to the thunderstorm in summer afternoon as "northwest rain" and describe it as "northwest rain, falling on the driveway", "summer rain over the ridge" and "summer rain over the cow's back", which vividly shows that thunderstorms often rain here and sunny there.

Guide to healthy eating in hot summer

Summer diet conditioning is based on summer climate characteristics. Because of the hot climate in summer, it is easy to hurt body fluid and consume gas, so porridge can often be used to nourish the body. Huangdi Neijing has the saying that "medicine can be removed and food can follow" and "grains, meat, fruits and vegetables can be eaten and nourished".

Medicinal porridge

Li Shizhen, a famous doctor, highly praised the health care function of medicated porridge. He said: "Eat a big bowl of porridge every day. If you are hungry, it will be ready when you are full of energy. The tonic is not fine, but it is extremely soft and greasy, which is compatible with the stomach. It is also the most wonderful diet. " Medicinal porridge is suitable for the elderly, children and people with weak spleen and stomach function. Therefore, the ancients said that "porridge is the best in the world" and "two rice meals are better than a big bag of ginseng and astragalus".

"Six Books on Medicine" praised: "Japonica rice porridge is used in Kundan biochemical cultivation, and glutinous rice porridge is a wonderful product for warming stomach and nourishing qi". It can be seen that porridge is important to people. Medicinal porridge is beneficial to human body, but it is not omnipotent. According to everyone's different physique and diseases, we should choose the right medicine and cook porridge to achieve satisfactory results.

drink water

In summer, water is also an indispensable substance for human body. Due to the hot weather, the human body's water evaporates and consumes too fast, so it needs to be replenished in time. It is best to drink boiled water at ordinary times. You can also use mung bean water, chrysanthemum tea and other summer medicinal teas. If you sweat a lot, you can use sugar, salt water, tea and other appropriate supplements of salt and minerals to maintain the electrolyte balance of the body and avoid dehydration.

In midsummer, yang heat drops, fumigation accumulates, water vapor rises, and moisture is full, so in this season, there are more people who feel damp and evil. In traditional Chinese medicine, dampness is a yin evil, which tends to be downward, heavy and sticky, easily deterring qi movement and damaging Yang Qi. Dietotherapy and medicated diet should clear away heat and relieve summer heat.
