What are the solar terms behind the great summer heat?

What is the solar term behind the heat? What is the next solar term?

After the heat, beginning of autumn solar terms. Beginning of autumn doesn't mean the hot weather is over. It is still very hot in early autumn.

Beginning of autumn means rain, storm, humidity, etc. At the turning point of the year, it tends to decline or decrease. Seasonal changes, rainfall, rainstorm, dry and wet changes in southern China are obvious; In the northern region, these changes are not obvious, but the temperature is obvious. After entering autumn, in nature, the qi of Yin and Yang began to change, everything began to grow from lush to mature, and the climate began to transition from rainy and humid in summer to dry and rainy in autumn. The beginning of autumn does not mean the end of hot weather. As the saying goes, "the summer heat is in dog days", according to the calculation method of "dog days", beginning of autumn is often in dog days until the summer heat, so the weather is still very hot in early autumn, and it will generally get cold after the Millennium solar terms. The watershed of summer heat is in autumn, not at the turn of summer and autumn. The climate in autumn is divided into two stages, the early autumn is sultry, and the climate tends to be dry and cool after the Mid-Autumn Festival. This is a season of alternating hot and cold.

"beginning of autumn" is often at noon. The so-called "three-volt fever" can be divided into initial, middle and final three volts, and its date is determined by the date of the solar term and the date of the branch year. According to China's traditional calculation method, the third and fourth Geng days from summer to the future are the first (head) and middle start dates respectively, and the first Geng day after beginning of autumn is the last first day. Because every Geng day is 10 days apart, the stipulated time of the first day and the last day is 10 days. Because the third Geng day (the first autumn) after the summer solstice solar term appears sooner or later, the number of days in autumn is long or short, which may be 10 or 20 days. According to the three-volt calculation method, "beginning of autumn" is still in the mid-volt period, that is to say, entering the "beginning of autumn" solar term does not mean that the temperature will drop.

Is it hot in summer or early autumn?

Compared with Qiu Lai, it is hotter in summer, but beginning of autumn is still in dog days for some time, so we should also pay attention to heatstroke prevention and cooling.

The reason why it is so hot during the summer heat is that Nanjing is often controlled by subtropical high, with high temperature and summer heat and little precipitation. In addition, usually since the summer, the heat absorbed from the ground sun during the day is more than the heat emitted at night, and the heat continues to accumulate. In summer, the accumulated heat reaches its peak, so the summer solar term is the hottest.

Extreme high temperature weather often occurs in many areas of our country. On a sunny day, it is often unbearably hot; It's stuffy and hard to breathe when it rains. There are folk proverbs such as "a little summer heat, steaming on the top and cooking on the bottom", "Misgurnus died of heat before and after the great summer heat" and "the great summer heat is coming, the summer heat is coming".

"It's so hot after beginning of autumn". Before and after beginning of autumn, the temperature in most parts of China is still high. According to the calendar, the first Geng Day in beginning of autumn is the first day of the last autumn.

The phrase "summer is not thorough, and summer comes after autumn" means that if it is not very hot in summer, the real heat will appear after autumn, and the hot spots in autumn are very conducive to harvest and will increase food production.

The ancient book says, "The great is extremely hot." The degree of summer heat is from small to large, and after the summer heat, it is beginning of autumn, just in line with the law that extremes meet. When the summer heat is at its peak and hottest, the peak of this summer heat will definitely turn from prosperity to decline. After the heat, the golden water went into the air, and the weather in beginning of autumn turned cold, which was in line with the natural law of the ancients to predict the weather. If the weather is not hot during the summer heat, it will still reach the peak of the summer heat after the beginning of autumn.
