Abstract:
Abstracts: Based on the data from China National Knowledge Infrastructure (CNKI) and Web of Science (WOS), this study used CiteSpace to systematically analyze the development trends of extreme precipitation research in China from 2004 to 2023 in terms of the number of publications, research teams, and hot topics. The results are as follow. (1) the annual publication volume of both Chinese and English journals exhibited an upward trend from 2004 to 2023. The annual publication volume of English papers exceeded that of Chinese after 2018. (2) The primary contributing scholars in the field included Zhang Qiang, Wang Xiaojun, Yin Yixing, Chen Xiaohong, and Gao Tao. For research institutions, Nanjing University of Information Science & Technology, Institute of Atmospheric Physics, Chinese Academy of Sciences, and Chinese Academy of Meteorological Sciences played the main roles. (3) The research hotspots focused on data assessment, spatiotemporal evolutionary characteristics, and occurrence mechanisms of extreme precipitation. Future research should pay more attention to integrating multi-source data products with AI-based meteorological large models for high-precision spatiotemporal monitoring and impact assessment of extreme precipitation, to help regional disaster prevention and mitigation.
