Every year around 65438+February 7 in Gregorian calendar, when the sun reaches 255 degrees of the Yellow Meridian, it is a "heavy snow" solar term. The twenty-four solar terms are the product of agricultural civilization, and the main climatic factors affecting agricultural production are precipitation, temperature and light. Like the light snow solar terms, the heavy snow solar terms reflect the changing trend of temperature and precipitation, and are the reflection of agricultural culture on festivals. Heavy snow is a solar term reflecting climate characteristics. Climate factors include precipitation, temperature and light, among which precipitation is an important factor.

Meteorology, rain, snow, hail and other water vapor condensation falling from the sky to the ground are called "precipitation". The arrival of heavy snow in solar terms means that the weather is getting colder and colder and precipitation is increasing.

Heavy snow meteorological change

"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".

The heavy snow in solar terms and the heavy snow in weather have different meanings. In fact, the snow in heavy snow solar terms is often not as big as that in light snow solar terms, and the solar terms with the largest amount of snow in the whole year are not in light snow and heavy snow solar terms.
