Why does it snow in winter?

Sister Dong will bring winter scenery, ice and snow weather.

In many areas, winter means silence and desolation. When the cold current strikes, living things will reduce their life activities, many plants will shed leaves, animals will choose to hibernate, and some are called hibernation. Migratory birds will fly to warmer places for the winter.

In some areas of southern China, it is always warm as spring during the winter solstice and the Light Snow Festival (equivalent to October of the lunar calendar), so that some fruit trees mistakenly think that spring has come and bloom for the second time. As the saying goes, "it's warm in August and warm in September, and it's sunny in October."

Extended data

In northern China, snow is an important symbol of winter. In the middle and lower reaches of the Yellow River in northern China and its vicinity, the snow in winter is often not as big as the light snow solar terms. The main reason is that the light snow solar term is ahead, the temperature is high, the total amount of water vapor in the air is larger than that of heavy snow solar term, and the possibility of heavy snow is greater.

In fact, the solar term with the heaviest snow in the middle and lower reaches of the Yellow River and its vicinity is neither "light snow and heavy snow" nor "slight cold and severe cold" (because the temperature was low at that time and there was less water vapor in the atmosphere), but a rainy solar term in spring.
