When is the heavy snow in 2022?
Heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. When the sun reaches the longitude of 255 degrees, the intersection time is from February 6 to 8, 65438 in Gregorian calendar every year. 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. 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.
Snow is the product of cold water vapor, representing cold and precipitation. Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term, namely temperature and precipitation. Like the light snow solar term, the heavy snow solar term is a solar term reflecting the changing trend of temperature and precipitation, and it is also a reflection of ancient farming culture on festivals.
Introduction of solar terms:
Heavy snow is a solar term reflecting climate characteristics. The characteristics of heavy snow solar terms are that the temperature drops obviously compared with autumn and early winter, and the precipitation increases. During the heavy snow season, most parts of China have entered the cold winter, and the minimum temperature in some parts of the north has dropped to 0 degrees Celsius or below. Cold and warm air in areas where strong cold air fronts meet, precipitation (rain or snow) increases. Meteorology, rain, snow, hail and other water vapor condensation from the sky to the ground is called precipitation.
Agriculture is the foundation of the world. Farming refers to farm work, and farming time refers to farming opportunities. Doing farming according to the farming season will get twice the result with half the effort. Due to the great difference in climate characteristics between the north and the south of China, the main agricultural activities in the north and south are also different accordingly. In winter, the northern region is covered with snow, so it is almost impossible to grow crops. At this time, there is little field management in the northern region, which is the slack season.
