Description 685-692
Extreme events have significant impacts on the coastal and offshore regions. In the present paper, the return values of
significant wave height and wind speed are estimated based on three different models namely generalized extreme value
distribution, generalized Pareto distribution and polynomial approximation to acquire a universal and trustworthy model
estimate. Here, six sites in the South China Sea with diverse geographical characteristics are considered to perform the
extreme value analysis and the datasets used in the experiments were derived from the ERA-Interim reanalysis. Then the
advantages and shortcomings of three different methods are discussed and analyzed in detail. The polynomial approximation
method is analyzed and compared with the other methods, and it is found that this new method predominantly resolves the
drawbacks encountered by the other typical extreme value estimation methods and it is suitable for estimating the return
values in the South China Sea.
