摘要

An increasing number of marine structures have been built for coastal protection and marine development in recent years, and wind, which is crucial to marine structures, should be analyzed. Therefore, typhoon frequency, wind climate, wind energy assess-ment, and extreme wind speed in the South China Sea (SCS) are investigated in detail in this study. The data are obtained from the China Meteorological Administration, the European Centre for Medium-range Weather Forecasts, and the National Centers for Envi-ronmental Prediction. The offshore wind energy potential is analyzed at five sites near the coast. The spatial and monthly frequencies of tropical cyclones for different intensity categories are analyzed. The extreme wind speed is fitted by five distribution models, and the generalized extreme value (GEV) distribution is selected as the most suitable function according to the goodness of fit. The spa-tial distributions of extreme wind speeds in the SCS are plotted on the basis of the GEV distribution and ERA5 data sets. The influ-ences of the distribution models and data sets on the calculated results are discussed. Moreover, the monthly extreme wind speed and comparison with the results of previous studies are analyzed. This study provides a reference for the design of wind turbines.
