Abstract:Using station observation data and reanalysis data, a summary was conducted on the climatic characteristics of China in 2025. The results are as follows. China exhibited distinctly warm and wet climatic characteristics in 2025. The annual average temperature in China was 10.9℃, which is 1.0℃ above normal and ties with that in 2024, marking the highest level since 1951. The annual precipitation was 668.0 mm on average, which is more than normal by 4.5%. The major weather and climate events in 2025 are as follows. In summer, extremely severe rainstorms occurred in North China, Northeast China and Inner Mongolia, with the central and eastern parts of China experiencing the fourth-severest heat wave events since 1961. Autumn typhoons influenced South China more than normal. In addition, severe convective weather events led to significant localized disasters, while the regional meteorological droughts had periodic characteristics clearly. Moreover, there were more cold wave processes and more high wind days recorded. In spring, sand-dust events became a frequent phenomenon.
