WAVE REGRESSION EQUATION FOR ASSESSING IMPACT OF CLIMATE CHANGE

Abstract

 Climate change impacts on waves can be quantitatively evaluated by conducting large-scale numerical wave simulations with typhoons extracted from the d4PDF dataset. However, due to an extensive number of typhoons in the d4PDF dataset, it is difficult to carry out wave simulations for all of them. Therefore, we propose a method for estimating the maximum significant wave height by developing a wave regression equation based on the results of a limited number of wave simulations, instead of performing simulations for every typhoon. The wave regression equation takes into account the time-varying wind field which is critical to wave growth. To validate the accuracy, we employed the k-NN model. Furthermore, we determined the minimum number of numerical wave simulations required to construct the wave regression equation.
