What season did the heavy snow fall?

"Twenty-four solar terms" said: "There is heavy snow, November Festival, and there is abundant snow so far." Because "snow" is a product of cold, representing cold and rainy weather, this solar term is characterized by a significant drop in temperature, and strong cold air can often bring rain or snow.

The name "heavy snow" is a metaphor, which reflects the climate change during this solar term. The cold current is active, the temperature drops and the precipitation increases, but it does not mean that there is heavy snow under this solar term. However, after the solar term of heavy snow, the weather will get colder and colder, and the possibility of snow will greatly increase.

The temperature after the solar term of heavy snow

In the heavy snow season, except in the winter-free areas such as South China and South Yunnan, the vast land of our country has been covered with winter clothes. The average temperature in Northeast and Northwest China dropped to-10℃, and the temperature in the Yellow River Basin and North China remained below 0℃. In normal years, snowfall has occurred in the Yellow River Basin and northern areas, and winter wheat has stopped growing.

After the heavy snow, Jiangnan entered the middle of winter, and the temperature in various places dropped significantly, and freezing often occurred. "After the winter solstice of heavy snow, the water in the basket does not leak" is a true portrayal of this time, but it is not the case in some years. There is no freezing phenomenon in high temperature, which often leads to more rain in the later period.

The growth of wheat and rape in Jianghuai and its south area is still slow, so it is necessary to pay attention to applying wax fertilizer to lay a good foundation for safe overwintering and spring growth next year. When wheat in South China and Southwest China enters the tillering stage, tillering fertilizer should be applied in coordination with intertillage, and attention should be paid to ridge cleaning and drainage of winter crops.

Although the weather is cold at this time, the stored vegetables and potatoes should be inspected frequently and ventilated in time, and the cellar should not be closed too dead, so as to avoid the temperature rise and excessive humidity leading to rotten cellar. The temperature should be kept as low as possible to avoid freezing.
