From April 16 to 18, 2025, the 21st National Workshop on Tropical Cyclones (NWTC-XXI) was held in Changsha, Hunan. The workshop, co-hosted by the China Meteorological Society and the Shanghai Typhoon Institute of the China Meteorological Administration, and organized by the Typhoon Professional Committee of the China Meteorological Society and the Asia-Pacific Typhoon Collaborative Research Center (AP-TCRC), provided a platform for researchers and practitioners in the field of typhoons to share their latest research findings on cutting-edge scientific issues related to tropical cyclones. Professor Johnny C. L. Chan, Dr. Tang Jie, and young researchers Chen Hao, Tang Lichun, and Wang Yue from the center attended the meeting and shared their academic achievements.

Professor Johnny C. L. Chan delivered an invited keynote speech titled "Impact of Land-sea Contrast on the Track of Pre-landfalling Tropical Cyclones." Dr. Tang Jie presented an invited keynote speech titled "Progress of Typhoon Observation and Forecasting Experiments in 2024 and Plans for 2025." Chen Hao showcased the research results titled "Precipitation Retrieval from Geostationary Satellite Data Based on a New QPE Algorithm," which improved the accuracy of precipitation estimation in extreme weather events such as typhoons through the optimization of satellite QPE algorithms. Tang Lichun presented the research titled "Verification of Global Tropical Cyclone Operational Forecast in 2022," which systematically evaluated the performance of domestic and international subjective forecasts and mainstream numerical forecasting models, providing a scientific basis for improving forecasting systems and significantly contributing to the enhancement of typhoon forecast accuracy. Wang Yue presented the research titled "Modifying the ARCHER algorithm to improve the tracking of weak tropical cyclones in the western North Pacific," which proposed a solution to the technical challenge of locating low-intensity typhoons. The improved algorithm significantly enhanced the accuracy of weak typhoon center location, providing reliable technical support for typhoon track monitoring.

The active participation of the center's researchers highlighted the mission and responsibility of young meteorological scientists to strive for excellence. Moving forward, the center will continue to deepen key technological innovations in tropical cyclones and contribute its wisdom to strengthening the ability of meteorological disaster prevention and mitigation.
