It doesn't snow in heavy snow and solar terms.

Heavy snow is one of the 24 solar terms. Heavy snow doesn't mean it will snow on this day. Heavy snow is a solar term reflecting climate characteristics. Heavy snow solar terms are characterized by a significant drop in temperature and an increase in precipitation. The ancients said: "The great man is prosperous, and the snow man is prosperous here." .

At this time, it often snows heavily and widely, hence the name heavy snow. At this time, the lowest temperature in most parts of China has dropped to 0℃ or below. Heavy snow and even snowstorms often fall in areas where cold and warm air meet at the front of strong cold air.

Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term, namely temperature and precipitation. Heavy snow means colder weather, and the possibility of snowfall is greater than that of light snow. This doesn't mean that there must be a lot of snowfall. So it depends on the weather when it snows.

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.
