What is the solar term after the winter solstice?

After winter, the solstice is a little cold.

Solar terms refer to the 24 solar terms and climate, which is a supplementary calendar made by China to guide farming in ancient times. In China, the lunar calendar is a combination of yin and yang, which is based on the movement of the sun and the moon, so adding 24 solar terms can better reflect the cycle of the sun.

24 solar terms:

The beginning of spring? Rain? Scared? Equinox? Qingming? Grain Rain? Long summer? Little man? Mangzhong? Summer Solstice? A little hot? Summer heat? Beginning of autumn? Summer? White deer? Autumn equinox? Cold dew? First frost? Beginning of winter? Xiaoxue? Heavy snow? Winter solstice? Slight cold? Major Cold

The naming of the twenty-four solar terms reflects three seasons, phenology and climate changes.

Beginning of spring, Spring Equinox, Changxia, Lixia Solstice, beginning of autumn, Autumn Equinox, beginning of winter and Winter Solstice, also known as Eight; Phenological phenomena are amazing, clear, rich and complex.

Climate change is manifested in rainfall, Grain Rain, slight summer heat, severe summer heat, intense heat, white dew, cold dew, first frost, light snow, heavy snow, slight cold and severe cold.

Festival and qi:

Twenty-four solar terms, according to the position change of the sun in a year and the evolution order of the ground climate caused by it, the ancients divided the 365 1/4 days of a year into 24 segments and 12 months to reflect the four seasons, temperature and phenology. This is the twenty-four solar terms. There are two sections every month. The first section is called "Festival" and the middle section is called "Qi".

The ancients divided a solar year into seasons, knots, qi and climate, 1 year =4 seasons = 12 knots = 12 qi =72 climate, which is the definition of seasons and climate. Twelve months, every month, a "festival" is set, with "qi" in the middle, just like twelve bamboo festivals, which are inflated in the middle. This is the origin of solar terms and the original intention of honesty and thrift.

Twenty-four solar terms are divided into twelve solar terms and twelve qi (middle qi). There is a festival and a breath every month. The solar term is the beginning of a month and the solar term is the end of a month. In China, the lunar calendar designated the month with only festivals and no breath as the leap month of last month. The festival is lifeless, that is, the lunar leap month.

In addition to the winter solstice and slight cold:

Winter solstice

Winter solstice is a solar term divided by astronomy, which was called "short day" and "short day" in ancient times. From winter to the sun, the sun is located at 270 degrees of the Yellow Meridian, and the sun shines almost directly to the Tropic of Capricorn, which has the shortest day in the northern hemisphere. There is no 10 hour from sunrise to sunset in all parts of Sichuan. From winter to the future, as the earth orbits the sun, the direct sunlight belt gradually moves northward, making the days in the northern hemisphere gradually longer and the nights gradually shorter. In winter solstice, although the height of the sun is the lowest, the sunshine time is the shortest, and the heat absorbed by the ground is less than the heat lost, the heat accumulated on the ground for a long time continues to be lost, and the temperature near the ground layer has not dropped to the lowest, so it is not the coldest time of the year. After the winter solstice, although the days are getting longer and shorter, the days are getting shorter and shorter, and the nights are getting longer and longer in the short term. The heat absorbed by the ground every day is still less than the heat lost, so the temperature did not rise immediately. The masses are used to counting nine from the solstice in winter, and every nine days is a "nine". Before and after "March 9th", the area was the least hot and the weather was the coldest, so it was said that "March 9th was cold". Astronomy regards the winter solstice as the beginning of winter, which is obviously late for most parts of China. During the winter solstice, the average temperature in the western Sichuan Plateau is generally below 0℃, while the average temperature in the Sichuan Basin is only about 6℃ to 8℃. In the low-altitude valley area of southwest Sichuan, even in the coldest local165438+ in early October, the average temperature is still above 10℃, so it can be said that autumn comes and spring comes, and there is no winter all year round.

Minor Cold

Cold means cold, and slight cold means the degree of cold. As the saying goes, "March 9th is cold". "Sanjiu" is mostly from 65438+1October 9 to 17, which is also within the slight cold solar terms. But this is just a general rule. In a few years, a bad cold may be colder than a mild one. People still remember the winter of 1975, and the lowest temperature solar term was actually heavy snow! The winter warmth in Sichuan Basin is remarkable. In the winter of 65438+ 10, frost and snow invaded the east of the Three Gorges, often freezing, and the lowest temperature was about-10℃. However, the lowest temperature in the northern part of the basin is rarely below MINUS 5℃, and the low temperature below 0℃ in the southern part of the basin is even rarer. The coldest area in Sichuan in the middle of winter is the northern Sichuan Plateau. The lowest temperature can reach about -30℃. It's freezing, dripping into ice. The low-altitude valley in southwest Sichuan is the warmest place in Sichuan in the middle of winter. The average temperature in 65438+ 10 is around 12℃, and only a few teenagers may have a low temperature below 0℃. In addition, the inversion effect is very significant, so tropical fruits such as bananas and mangoes can grow well. The lowest temperature in the basin in winter is not low, which is beneficial to non-spring production and diversified management. Citrus, which is forbidden to move, grows in the south. Generally, the minimum temperature is not lower than minus 5℃, and the annual temperature is higher than 15℃, which can be met in most areas of the river basin, and almost all subtropical plants exist. Sichuan is called "Land of Abundance", and its unique climatic conditions should be a very important factor.
