Abstract

A general framework of typhoon full-track simulation for the Western North Pacific (WNP) basin is presented in this paper. Specifically, an empirical TC track model integrated with two intensity models, i.e., a classical Vickery intensity regression model (VIRM) and a novel Markov Environment-Dependent Hurricane Intensity Model (MeHiM) are developed. The applicability of MeHiM for typhoon simulation in WNP basin is validated by comparing several metrics (i.e., intensity spatial distribution, probabilistic distributions) with those from observation data. The full-track model parameters are calibrated and modified for the local area of the WNP basin, and storm tracks from the genesis to lysis are generated. The proposed full-track typhoon simulation framework together with a widely-used wind field model is employed to estimate design wind speed with a given return period for ten major cities of Southeast China. The results show that the estimated 100-year return period design wind speeds in simulated tropical cyclone climates are in good agreement with that prescribed in the current design code for some cities. For other cities, the comparison is complicated.
