Abstract
Future projections of ocean wave climate related with global warming has been conducted for the assessment of climate change impacts on coastal disaster, beach morphology, and coastal structure design. In this study, we conduct the high-resolution future wave climate projection in the East Asia region and detail analysis on wave climate based on two-dimensional wave spectra in addition to conventional wave statistics (significant wave height). Future changes in wave height, period and direction can be discussed consistently owing to analysis on the mean wave spectra.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/FEYPZFRr5SQ

Temporal averaged significant wave height, mean wave period, and mean wave direction are newly defined by based on temporalaveraged wave spectra
Summary
Future projections of ocean wave climate related with global warming has been conducted for the assessment of climate change impacts on coastal disaster, beach morphology, and coastal structure design. In terms of ocean around Japan, Shimura et al (2016) analyzed CMIP5 based wave climate projection dataset and showed significant decreases in mean wave heights around Japan under global warming condition. The previous studies on future wave climate assessment have been based on the data of global scale, and the computing resolution is not enough for the assessment of coastal wave climate with ~10 km scale.
