Female teacher of heavy snow and solar terms

Heavy snow is 2 1 of the 24 solar terms, and it is also the third solar term in winter, just like the light snow solar term.

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.

Historical origin:

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.
