A complete introduction to the snow season

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.

Date calculation

[Y*D+C]-L

Interpretation of the formula: Y= two digits after the number of years, D=0.2422, L= leap year, 2 1 century C=7. 18, and 20th century =7.9.

For example, the date of heavy snow in 2088 = [88× 0.2422+7.18]-[88/4] = 28-22 = 665438+heavy snow on February 6.

Exception: 1954 plus 1 day.

Basic characteristics of heavy snow weather

During the heavy snow season, except for South China and South Yunnan, most parts of China have entered the winter. The average temperature in Northeast and Northwest China is below-10℃, and the temperature in the Yellow River Basin and North China is also stable below 0℃. At this time, it has gradually snowed in the Yellow River basin, but it has been snowing in the farther north. However, in the south, especially in Guangzhou and the Pearl River Delta, the vegetation is still lush and the feeling of dryness is still obvious, which is quite different from the climate in the north. The winter climate in southern China is mild, with little rain and snow. The average temperature is about 2℃ to 4℃ higher than that in the middle and lower reaches of the Yangtze River, and the rainfall accounts for only about 5% of the whole year. Occasionally it snows, mostly in 1 and February; Snow on the ground is hard to see once every three to five years. At this time, the climate in South China is still foggy. Generally, 65438+February is the month with the most foggy days. Fog usually appears on cloudless nights or partly cloudy mornings. Meteorology calls it radiation fog. "Ten fogs and nine sunny days", most of the fog dissipates before noon, and the sunshine in the afternoon will be particularly warm.

The origin of heavy snow

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.
