| Outline of Final Research Achievements |
This study analyzed seasonal to multi-decadal variation of long-term wave climate based on JRA-55 reanalysis and future wave climate projections. The 3rd mode of monthly mean wave height shows 5 to 10 year period variations based on principal component analysis. The monthly mean wave height in winter season shows clear correlation between Western Pacific (WP) index. The response of monthly mean wave height in winter season around Japan to WP index is opposite in comparison between the eastern and western Pacific coast of Japan. Furthermore, future changes of monthly mean wave height in winter season around 30 degree in the latitude will be decreased based on multi-model ensemble of future wave climate projection.
