Abstract: The risk of high wind speeds in the Hangzhou Olympic Sports Center Stadium Area during the Asian Games was assessed by using Computational Fluid Dynamics (CFD) method during the the typhoon Krosa period. The results show that the model is reliable, with an absolute error within 0.3 m/s. Under the initial simulation conditions of a fresh gale, the average wind speed inside the area is 12.9 m/s. Wind speeds exceed 30 m/s in narrow passages between high-rise buildings, with a maximum wind speed of 35.7 m/s. Areas at risk of wind intensity exceeding 24.6 m/s (capable of uprooting trees) account for 4.3% of the total area. Areas with wind intensity exceeding 20.8 m/s (capable of damaging roof tiles) constitute 9.8% of the total study area. The Hangzhou Olympic Sports Center Stadium benefits from the protective effect of surrounding buildings and experiences less impact from strong winds, thereby providing better protection for spectators and athletes. This research has significant implications for formulating relevant strategies to strengthen monitoring and intervention capabilities for strong winds in sports venues during the Asian Games, particularly for outdoor sports facilities within the venue area. The implementation of emergency control measures and safeguards in key areas through a grid-based approach with minute-level meteorological forecasts is recommended.
