heavy snow (Blizzard) strong cold air meets warmer air, cold and heat meet, which can often form a large amount of snow or even blizzard.

snowfall can help alleviate winter drought and freeze pests, which is conducive to the development of winter tourism; However, excessive snowfall will lead to snow on the road area, turn snow into ice, and affect road traffic and civil aviation.

freezing rain (RIME) the cold air continues to go south to the south of China, especially Guizhou, Hunan, Hubei and other places, which is easy to form freezing rain. Snowflakes falling at high altitude melt into rain at the middle level, continue to be cold at low altitude, and become supercooled water in the form of raindrops although it is lower than 0 ℃. Any object falling on the ground will freeze immediately. Although the freezing rain of
