The origin and significance of solar terms in heavy snow

1, 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. The ancients named this solar term "heavy snow" because "snow" is the product of cold water vapor, representing cold and precipitation. This solar term is characterized by a significant drop in temperature, 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 it will snow heavily in this solar term.

2. Heavy snow is the second1solar term among the 24 solar terms and the third solar term in winter. Heavy snow, fingers crossed, the sun reaches 255 degrees of the yellow meridian, and the node time is February 6-8, 65438.

3. Like the light snow solar terms, the heavy snow solar terms reflect the changing trend of temperature and precipitation, and are the reflection of ancient farming culture on festivals. 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.

4. 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. For example, in the middle and lower reaches of the Yellow River, according to the standard of 24 solar terms, the solar term with the largest annual snowfall is neither "light snow nor heavy snow" nor "slight cold or severe cold", but "rain" in spring. This snow is not the biggest in the solar terms.
