The Vickery model is improved by optimizing the regional division,and introducing the direction angle of tropical cyclone movements and the land ratio of sea-land alternate zones in this paper.Taking the tropical cyclone landing in the southeast coastal area as an example,the simulated central pressure difference value of the improved model for the tropical cyclone is compared with the observed value and the simulated result of existing models.The results show that the improved model enhances the central pressure difference simulation effect of the tropical cyclone penetrating the land with the direction of tropical cyclone movement when landing,and enhances the central pressure difference simulation effect of the tropical cyclone near the coastline with the land ratio.
