Abstract: In the winter of 2023/2024, the national average temperature was −2.8℃, which was 0.3℃higher than the same period of the perennial value (1991−2020). The average precipitation in winter was 50.8mm, 19.8% higher than the same period, showing a distribution pattern of more in the north and less in the south. Many places in the central and eastern regions have more snowfall days, more accumulated snowfall and deeper snow. The national average sunshine was close to perennial value, and the eastern part of southwest China is more than the same period. Most regions of the winter wheat areas in the north have abundant light and heat conditions, within many large-scale rain and snow weather were conducive to soil moisture increase. The soil moisture is the best in the past decade, and meteorological conditions are conducive to the safe overwintering of winter wheat. Most regions of southern was enough warm and sunshine hours for the growth and development of rape, wheat, winter crops and economic fruits. In winter, the central and eastern regions experienced three large-scale cold wave weather processes, which affected the production of protected agriculture, and some rape, open vegetables and economic forest fruits in southern provinces were frozen. There is much snowfall in Northeast China and northern Xinjiang, which is not conducive to agriculture and animal husbandry production.
