Knowledge of solar terms in heavy snow

The knowledge of heavy snow solar terms is as follows:

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.

Meteorological changes:

"Heavy snow" is a solar term reflecting the climate characteristics. The characteristics of heavy snow solar terms are that the temperature drops obviously compared with autumn and early winter, and the precipitation increases. During the heavy snow season, most parts of China have entered the cold winter, and the minimum temperature in some parts of the north has dropped to 0℃ or below. Cold and warm air in areas where strong cold air fronts meet, precipitation (rain or snow) increases. Meteorology refers to the condensation of water vapor falling from the sky to the ground, such as rain, snow and hail, as "precipitation".
