Abstract:

 In the autumn of 2024 (September−November), the national average temperature was 11.5°C, which was higher than the average of the same period from 1991 to 2020, and consecutively increased in the sixth year as well as created a new high record since 1961. The national average precipitation was 134.4mm, and 14.4% more than the same period from 1991 to 2020. The national average sunshine hours were 536.5h, and 6.0% less than the same period from 1991 to 2020. In most agricultural areas across the country, the light and heat conditions in autumn were relatively good to the crops. The first frost date in the northeast China was later than usual, and the cold dew wind had little impact on the late rice in the south part of China. The meteorological conditions were conducive to the filling and ripening, harvesting, drying of autumn-harvest crops and sowing of autumn-planted crops. Overall, the harvest and planting activates progressed smoothly in autumn of 2024, excluding the periodic droughts in the eastern part of the Sichuan basin and the middle and lower reaches of the Yangtze river, which affected the quality improvement of economic forest fruits and the sowing and emergence of autumn rapeseed. Nearing to the end of this period, a cold snap weather caused heavy snowfall mainly in the northeastern part of Inner Mongolia and northeast China, which is unfavorable for agricultural and pastoral production.
