The extreme value analysis of wave height has been used to estimate design value of coastal structure design.The procedure of extreme value analysis is standardized but distributions change highly depending on target locations. Although the reanalysis dataset was insufficient for coastal engineering applications due to shorter length of period and sparse spatial resolution of modeling, recent reanalysis give reasonable performance for engineering applications as wave climate both accuracy and length of periods.This study analyzes characteristics of extreme wave heights and understands relation between extreme wave height distribution and its dependence on weather systems based on long-term analysis and observed data.
