Reply to Discussion by ZJ. You of 'A multi-distribution approach to POT methods for determining extreme wave heights' by Mazas and Hamm

摘要

We strongly agree with Dr. You about the use of the POT method to extract independent peak storm wave heights to be fitted by statistical distributions for the extrapolation of extreme wave heights. We have tried to make clearer that regarding the choice of the threshold value, the necessity to account for both physical and statistical considerations can be properly dealt with a double threshold, each of them having a complementary but distinct role. Anyway, we do not consider that the single example of the particularly smooth and stable dataset of Gibraltar brings even a partial discredit on this approach. We have shown examples where such a distinction is much useful and even necessary.
