    Abstract:

    To explore the characteristics of wind field models, by taking Super Typhoon “Yagi” in 2024 as an example, a parameter sensitivity analysis of the Yan Meng wind field model was conducted via numerical simulation. The results show that the surface wind speed calculated by the Yan Meng wind field model is positively correlated with the pressure profile constant and the maximum wind speed radius, and the pressure profile constant is positively correlated with the maximum wind speed radius. A smaller equivalent roughness height leads to a higher surface wind speed. The relative error of the surface wind speed calculation results of the Yan Meng wind field model can be stabilized within 20%, and the average value of the mean absolute error is within 2 m/s. The Yan Meng wind field model exhibits good adaptability in the study of typhoon wind fields along the coast of China, and it can be applied to the evaluation of typhoon disasters along the coast of China.
