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.

"Twenty-four solar terms" said: "There is heavy snow, November Festival, and there is abundant snow so far." Because "snow" is a product of cold, representing cold and rainy weather, this solar term is characterized by a significant drop in temperature, and strong cold air can often bring rain or snow.

The name "heavy snow" is a metaphor, which reflects the climate change during this solar term. The cold current is active, the temperature drops and the precipitation increases, but it does not mean that there is heavy snow under this solar term. However, after the solar term of heavy snow, the weather will get colder and colder, and the possibility of snow will greatly increase.

The "heavy snow" in the sense of solar terms is not necessarily related to the "heavy snow" described in the weather forecast. Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term. The "heavy snow" in weather forecast refers to the snow with strong snowfall intensity.

According to meteorology, when it snows, the visibility is poor, the horizontal visual distance is less than 500 meters, the depth of snow on the ground is equal to or greater than 5 cm, or the snowfall is between 5.0 and 9.9 mm within 24 hours, which is called heavy snow.
