'heavy snow' is the 21st solar term in the 24 solar terms of the lunar calendar and the third solar term in winter, marking the official beginning of the midsummer season; At that time, the apparent sun reaches 255 degrees of the Yellow meridian. "The collection of the seventy-two seasons of the lunar calendar" said: "heavy snow, November Festival, so far, and the snow is full." Heavy snow means that the weather is colder and the possibility of snowfall is greater than that of light snow. It does not mean that the amount of snowfall must be great.
Introduction to heavy snow
'heavy snow' indicates that the snow began to fall heavily at this time. The winter climate in Sichuan Basin 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. Occasional snowfall, mostly in January and February; The area of snow is hard to see once in three or five years. If you can see the earth covered with snow and green trees covered with silver jade, it is often an interesting thing you will never forget. " Auspicious snow bodes well for a good harvest ', which is a widely circulated agricultural proverb in China. In the north, a thick and loose layer of snow is like a quilt for wheat to keep out the cold. Snow contains four times more nitrogen compounds than rain. The snow melts slowly and seeps into the soil, which can increase the nitrogen in the soil and is easy to be absorbed and utilized by crops. The low temperature of snow water can freeze to death the overwintering pests in the surface layer, and also bring benefits to agricultural production. However, in the south, if there is more heat loss on the ground every sunny night after snow, there will be freezing injury, causing certain losses to peas, peas and other crops. The average temperature in the basin of our province is still between 8 ℃ and 9 ℃, and wheat and rape can still grow slowly. It is necessary to strengthen field management and prevent freezing injury. During the heavy snow, the precipitation in the basin is mostly less than 15mm, and less than 5mm in the west of the basin. It is already a 'dry winter' period. At this time, the basin climate is also foggy. Generally, December is the month with the most foggy days. Fog usually occurs in the morning when there is no or little cloud at night. Meteorology calls it radiation fog. As the saying goes: 'ten fogs and nine sunny'. Most of the fog dissipates before noon, and the afternoon sun will be particularly warm.
