What do you mean by seasonal heavy snow?

Heavy snow is the 21st solar term among the 24 solar terms and the third solar term in winter. During this period, the weather was colder and the precipitation increased.

From light snow solar terms to heavy snow solar terms, it is a transition process from late autumn to winter. Generally speaking, the snowfall will increase.

For North China, Northwest China, North China and Northeast China, it can be said that the more transition to winter, the more snow there will be. From the precipitation stage, more rain turns into sleet or pure snowfall.

Regionally, in the northeast, northern North China, central and western Inner Mongolia, and Xinjiang in the northwest, the snowfall of heavy snow solar terms may be more than that of light snow solar terms. But there are still some differences between years.

Detailed introduction:

Heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. When the sun reaches the longitude of 255 degrees, the node time is 65438+February 6-8 in Gregorian calendar every year. The solar term of heavy snow is the beginning of the second month of the dry calendar, marking the official start of the mid-winter season. 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.

"Snow" is the product of cold water vapor, representing cold and precipitation. The heavy snow solar term is a climate concept, which represents the climate characteristics during the heavy snow solar term, that is, temperature and precipitation (water vapor condensate such as rain, snow and hail falling from the sky to the ground is called "precipitation" in meteorology). Like the light snow solar term, the heavy snow solar term is a solar term reflecting the changing trend of temperature and precipitation, and it is also a reflection of ancient farming culture on festivals.
