Summer is the twelfth solar term among the twenty-four solar terms and the last solar term in summer. The ecliptic of the sun is 120, which is from July 22nd to 24th in Gregorian calendar. "Summer heat" is heat, and summer heat is extremely hot.
Summer heat is hotter than summer heat. Summer heat is the most intense and hottest solar term in a year, and "hot and humid steaming" reaches its peak at this time. Climatic characteristics of the great summer heat: high temperature and intense heat, frequent thunderstorms and typhoons.
The summer solar term is the hottest time of the year, just before and after the "midsection" of the "dog days". In summer, the sun is like fire, the temperature is high, the humidity is high, and there is much rain. Although it is inevitable to suffer from high temperature and humidity, it is very beneficial to the growth of crops, and crops grow fastest during this period.
Since ancient times, there has been a folk custom of drinking herbal tea (tea) in the dog days of midsummer; Fucha, as its name implies, is a kind of tea to drink in dog days. This kind of tea boiled with Chinese herbal medicine has the function of cooling and dispelling summer heat. In addition, there are customs such as burning incense and drying ginger. "Great Summer" is the hottest and wettest season of the year, and the focus of health care at this time is "heatstroke prevention" and "dampness elimination".
The summer solar term is just around the Mid-Autumn Festival in the dog days, which is the strongest and hottest solar term in a year, 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.
Monsoon climate is the main feature of China climate. In summer, affected by warm and humid air currents from the ocean, many places in China are hot, humid and rainy. At this time, the sun is fierce, the temperature is high, the humidity is high, and there is much rain. Although it is inevitable to suffer from damp heat, it is very beneficial to the growth of crops, and crops grow fastest during this period.
The summer solar term is the period with the strongest sunshine and the highest temperature in South China, the period with the richest rainfall, the most common thunderstorm and the most concentrated high temperature days in the west of South China, and the period with the highest temperature above 35℃ in the east of South China.
The intense heat is also the hottest period of the year in most parts of China. Except for the Qinghai-Tibet Plateau and Northeast China, the weather is hot in most areas, and the high temperature of 35℃ is a common occurrence, and the high temperature of 40℃ often occurs. There is little difference in temperature between the south and the north of this country. In the northern inland areas, summer is dry and hot.
