"It will rain on sunny days in winter, it will be warm on the solstice in winter, and it will be very cold in spring". Is this sentence accurate?

This sentence is an ancient proverb handed down from generation to generation by our ancestors. If the winter solstice is sunny, it will definitely rain during the New Year in China. And if winter is warm, it will definitely get cold in the Spring Festival. Therefore, in ancient times, people often used the weather conditions and solar terms of the winter solstice to further speculate on the weather in the later period. This speculative method may not be accurate, but it is indeed a valuable asset that has been circulating for a long time.

The solar term on the solstice is the simplest way for farmers to calculate the weather. For the old farmers who like to turn over their calendars, they often refer to Tongsheng and the old yellow calendar a month ago to see the specific date of the winter solstice. In addition, the weather conditions on the day of the winter solstice solar term can also predict the rainfall in the coming year. For example, if the winter solstice is sunny, there will be more rain during the Spring Festival.

The winter solstice solar term usually represents the arrival of cold winter, because for people in all parts of the northern hemisphere, the winter solstice is the shortest day of the year. After the winter solstice, the law in the northern hemisphere is that the days are long and the nights are short, and the height of the sun rises gradually at noon, which shows that winter is really coming. At the same time, the winter solstice can represent the changing law of the weather from cold to coldest and then gradually warming, so the winter solstice is the simplest and most intuitive day to predict the weather and rainy weather.

There is an old saying: "If it is cold or not, the year will not be good", which means that abnormal climate will definitely cause changes in heat and cold. Different regions have different proverbs. In addition to this sentence, there is "if the solstice in winter is warm, it will be cold until mid-March;" If the winter solstice is very cold, it will get warmer soon next spring "and" if the winter solstice is warm, it will be as hot as fire before summer comes ",so this proverb is only a preliminary prediction.
