Characteristics of solar terms in winter on solstice

Short sunshine time: "After eating the winter solstice meal, the daytime becomes longer", and the daytime time increases from winter to the future. However, the solar radiation obtained on the ground is still less than the heat lost by the ground radiation, so the temperature will continue to drop in the short term. Low temperature and cold climate: during the winter solstice, the average temperature in the northwest plateau is generally below 0℃, and only 6℃ to 8℃ in the southern region.
