Will it snow in heavy snow and solar terms?
Of course, we should also know that even if the cold air goes south, there will be regional differences in the weather, such as snow in the north, sleet in the Yellow River basin, rainy days in the Yangtze River basin, and a slight drop in the south wind, all of which are caused by different latitudes.
The 24 solar terms such as light snow and heavy snow were summed up by the ancients. They are not only a supplement to the calendar, but also guidelines for agricultural activities, which are of great significance to farmers. Moreover, there was no weather forecast in ancient times, so the wise ancients summed up their own experience and saw what kind of weather would appear at each time of the year, and then recorded it.
Agricultural proverbs related to heavy snow and solar terms
First, the snow is not frozen and cannot be shaken.
The solar term of heavy snow is characterized by cold Zita Law, which is the time with the most snow. As the saying goes, "the land is sealed by light snow, and the river is sealed by heavy snow", which means that the river will freeze when it reaches the solar term of heavy snow. If the river does not freeze in the heavy snow season, it means that the temperature is still relatively high, at least above zero.
If the solar terms of heavy snow are not frozen, it means that the cold weather will be postponed later, because the sun's trajectory is almost fixed. When the sun moves to the same position, the ground temperature does not drop, and this cold will be preserved and postponed until later. The temperature will still be lower when it comes to the shocking solar terms.
Second, there is heavy snow, and there will be no shortage of rain in the coming year.
The second stage of light snow is: the weather rises, the atmosphere drops, and the third stage is blocked and becomes winter. Under the irradiation of the sun, the air on the ground is heated and rises. After encountering cold air at high altitude, rain and snow form. So the atmosphere will rise, the weather will fall, and the upper and lower parts can be connected. The light snow solar term is characterized by the fact that the atmosphere does not rise, the weather does not fall, and it becomes winter.
In the solar term of heavy snow, this kind of blocking force will be stronger, and it is not easy to form rain or snowfall unless the atmosphere rises. If blocked, it can also form rain and snow, which means that the humidity and temperature in the air are relatively high. The higher the temperature and humidity in winter, the more rain will come next year.
So heavy snow, solar terms, snow or cloudy days all mean more rain in the coming year. As the saying goes, "Spring rain is as expensive as oil". Spring is the time when crops turn green and thrive. When there is more rain in spring, the harvest of crops will be better. Therefore, "it doesn't snow in heavy snow, and people will eat iron in the coming year", because it doesn't snow in heavy snow and crops are prone to drought.
