Scientific principle of spring cold caused by heavy snow.

The scientific principle is that if there is no freezing before and after the solar terms of heavy snow, there may be late spring cold next spring.

The heavy snow solar term is the third solar term in winter. At this time, it has entered the deep winter, the temperature is normally low, and freezing has occurred in the north. This is a normal year. In this case, the climate will be normal next spring, and generally there will be no late spring cold. If the temperature is still high before and after the heavy snow solar terms, it means that there is an abnormality afterwards, and the cold air is weak in winter. In this case, the next spring, the probability of late spring cold will be higher.

Therefore, it is said that "heavy snow is not frozen and spring is cold". Heavy snow is not cold, and it is often cold in spring, but it becomes cold in spring. This weather indicates that it will be very dry next year. If you don't believe me, look at this proverb. As the saying goes, "heavy snow is not cold, and there will be a drought next year."

Cold in spring means when the snow is still there:

The general meaning of this sentence is that if the temperature is not cold after the arrival of the heavy snow solar term, then this year is undoubtedly a warm winter. I believe everyone can understand that "heavy snow does not freeze" means warm winter. Although the cold wave was fierce some time ago, and the rapid cooling made people unprepared, compared with the past, today's winter is actually not very cold, even a little warm.

This can be well seen from the growth of crops. Because of the warm weather, some winter wheat planted in rural areas in the north has been flourishing, which is the most intuitive performance of warm winter.
