Which solar term should I make up?
The basic explanation of the first frost is that the weather is getting colder and colder, starting from first frost, which is the 18th of the 24 solar terms. The first frost is the last solar term in autumn when the sun is at 2 10 on the 23rd or 24th of October in the solar calendar. The first frost refers to the first frost. Twenty-four solar terms say: "In mid-September, the air is cool and condensed, and the dew is like frost." At this time, when the temperature drops below 0 degrees, the water vapor in the air condenses into white crystals on the ground, which is called frost. At this time, the first frost usually appears in the Yellow River valley in China, and most areas are busy planting crops such as wheat. Plants that are not hardy will stop growing and present a scene of late autumn, which is a good opportunity to enjoy the maple leaves. Yizhoushu Zhou said: "Autumn and March are empty: summer, autumn equinox, first frost." "Mandarin Zhou Yuzhong": "See the fire and cool breeze to stop the cold." "The History of the Three Kingdoms Wu" notes: "As the saying goes, after the first frost, the breeze comes first, and people should have a cold heart." Wei Wei's "Oriental" Chapter 15: "In the solar terms, there are several frosts here before the first frost."
Overview of the first frost and the first frost solar terms-it's getting colder and colder and frosty. The first frost usually occurs on the 23rd or 24th of the Gregorian calendar 10 year 10. At this time, the first frost appeared in the Yellow River basin in China, and most areas were busy planting crops such as wheat.
In ancient China, the first frost was divided into three stages: "One stage was that the jackal sacrificed animals; Second, the vegetation is yellow; Three waiting insects are salty. " In this solar term, jackals will show their prey before eating; The leaves on the earth turned yellow and fell; The stinging insects are motionless in the cave and hang their heads into hibernation.
During the first frost period, that is, from 65438+1October in late June to1early October165438+1October, with the dry and cold air gradually dominating the whole country, warm and humid air was marginalized, and many weather phenomena with the characteristics of summer and early autumn basically withdrew from the sky stage. The weather is simpler than the previous period. Before and after beginning of winter, there were often strong winds and cool weather, and some places entered winter in a short time.
As far as the north is concerned, after the cold air, the sky is still high and the clouds are light, giving people a deep impression of cooling down again and again. Except for some places in the northeast and northwest, in places with high altitude, everything is dying and snowflakes are flying, and most areas in the south are "frosty leaves are red in February flowers", which makes tourists linger.
As far as South China is concerned, the autumn wind is cool after the rain, and the sky is clear, orange, yellow and green. People along the coast of South China are about to enter the threshold of autumn. The sunshine in late summer is not so hot. Blue sea and blue sky, golden beaches, flowers and green trees can be seen everywhere, the vast countryside is full of fragrance, and the rice harvest is in sight.
Of course, if you encounter a rare cold wave weather, it is not only a large area of cool wind and cold rain, but also a sharp drop in temperature. Frost caused by cooling will be a disaster for some crops that are not cold and warm, such as late rice and rape in the south.
