Abstract:

 In the winter of 2025/2026, the national average temperature was −2.1℃, which was the second highest temperature on the same period since 1961. There were 13 cold air events with notable temperature fluctuations of warmer−than−normal conditions. The average winter precipitation was 29.4mm, 25.2% less than the average for the same period from 1991 to 2020. The national average sunshine hours was close to the perennial value, and significantly more sunshine hours had been observed in the Sichuan basin compared to the same period in history. Much of the northern winter wheat region had abundant light and heat conditions, with most of the moisture for safe wintering and greening of the wheat within a wide range of rain and snow weather. Most areas of southern China had warm and sunshine hours for the growth and development of rape, wheat, winter crops and economic forest fruits. However, the phase of drought in southern Sichuan and northern Yunnan and the phase of low temperature in Jianghuai and Jianghan were not good for the steady growth of summer crops.
