Is heavy snow a solar term among the 24 solar terms? What's the story?

Heavy snow is one of the 24 solar terms.

The solar term of "heavy snow" is February 7 or 8 of 65438+ every year, and the sun reaches 255 degrees of the yellow meridian. "Twenty-four solar terms" said: "At this time, the snow is abundant." Heavy snow means colder weather, and the possibility of snowfall is greater than that of light snow. This doesn't mean that there must be a lot of snowfall. On the contrary, after the heavy snow, the precipitation in various places has further decreased. The average precipitation in June 5438+February in Northeast China and North China is generally only a few millimeters, but less than 1 mm in Northwest China. When heavy snow and snow are classified according to snowfall, the snowfall is generally 5.0 ~ 10 mm.

Origin:

65438+ On February 7th or 8th every year, when the longitude of the sun reaches 255 degrees, it is the "heavy snow" which is one of the 24 solar terms. Heavy snow, as the name implies, has a large amount of snow. The ancients said: "The great man is prosperous, and the snow man is prosperous here." . At this time, it often snows heavily and widely, hence the name heavy snow.

At this time, the lowest temperature in most parts of China has dropped to 0℃ or below. Often, in areas where cold and warm air meets strong cold air fronts, there will be heavy snow or even blizzard. It can be seen that the solar terms of heavy snow indicate the starting time of this period and the degree of heavy snow, which, like the solar terms of light snow, rain and Grain Rain, directly reflect the precipitation.
