This year's frost term is October 24. Frost term is the last term in autumn. Therefore, many people think that winter is after frost. Is it winter after frost? What does the arrival of frost term mean? Let's take a look at this article.
In ancient China, it was a folk custom to take the beginning of winter as the beginning of winter. The collection and interpretation of the seventy-two seasons of the lunar order said: 'the beginning is the beginning', and also said: 'winter is the end, and all things are collected.' In fact, China has a vast territory. With the exception of the South China coast where there is no winter all year round and the Qinghai Tibet plateau where there is no summer in winter, winter does not start at the same time.
According to the four seasons standard of climatology, it is winter when the average temperature drops below 10 ℃ in the second half of the year, so the saying that "the beginning of winter is the beginning of winter" is basically consistent with the climate law of Huang Huai Region in China. The northernmost Mohe River and the area north of the Daxing'an Mountains have entered winter as early as early as early September. The capital Beijing has also seen a winter scene in late October, and the winter in the Yangtze River Basin does not really start until before and after the 'light snow' solar term.
What does the frost solar term mean: the temperature drops and gets colder and colder
The frost term means that the weather is getting colder and begins to frost. In the southern region with south latitude, the average temperature is mostly about 16 ℃, and there are three solar terms before the first frost date. In the southern valley of South China, frost can only be seen in the middle of winter.
Of course, even in places with the same latitude, due to different altitude and terrain, the temperature and humidity of the air near the stratum are different, and the initial frost period and frost days are different.
In the frost season, the cool autumn wind has blown to the flower city of Guangzhou. The average temperature in the north of Northeast China, Eastern Inner Mongolia and most of Northwest China has been below 0 ℃.
