Abstract: In recent years, there has been an augmentation in the frequency of intense typhoons, particularly Super Typhoon "Yagi" (Typhoon No. 2411), which has caused substantial economic losses and social impacts in Hainan Province in China. This study compares the wind disaster assessment method based on accumulated wind energy, thereby mitigating the limitations of traditional assessments based solely on maximum wind speed. The research findings indicate that the accumulated wind energy model more precisely reflects actual disaster losses, especially in high-vulnerability areas such as Wenchang and Haikou in Hainan Province. The coverage area of winds greater than level 12 is 1473 km², level 13 is 933 km², level 14 is 101 km² in Hainan island. The overall wind energy of "Yagi" is higher than that "Rammasun", and the total wind energy of Typhoon "Yagi" in Wenchang City is about 13 times that of " Rammasun ", about 500,000 kJ. The study reveals the influence of factors such as typhoon wind speed, duration, and terrain on accumulated wind energy, thus elucidating the regional disparities in wind disaster risk. Under the background of climate change, it is recommended to improve wind resistance design standards and infrastructure resilience based on typhoon wind energy estimation results, especially for rural housing, agricultural facilities, electricity, communication and other infrastructure.
