What does the heavy snow solar term represent?

The arrival of heavy snow solar terms means that the temperature drops obviously, the precipitation increases, and it rains or snows. The ancients named this solar term "heavy snow" because snow is a product of cold and represents cold and rainy weather. The name "heavy snow" is a metaphor, which reflects the climate change of this solar term. The cold current is active, the temperature drops and the rain increases, but it does not mean how much snow will fall in this solar term.

During this solar term, there may be heavy snow or blizzard in the north and freezing rain (rime) in the south, such as Guizhou, Hubei and Hunan. Before and after the heavy snow festival, when strong cold air arrives, it is particularly prone to freezing rain (rime), while rime will appear in most areas of the northwest, northeast and Yangtze River basins, especially in mountainous areas with relatively high humidity. Both rime and rime are formed by water vapor or cold fog in the air freezing on objects at low temperature. Milky white ice crystal deposits hang on trees, as hazy as fog and water; As soon as the sun shines, it is wrapped in white, and Qiongyu Wonderland is beautiful. The places with more rime in China are Heilongjiang, Jilin, northern Xin Qiang and western Shaanxi. Rain and rime are beautiful, but some ice shells appear on the ground and objects, which will have a great impact on traffic, electricity and communication. If the tree is too full, it will also damage the fruit trees in a large area.
