Abstract

 Monthly mean wave heights gives significant impact on coastal morphology, harbor usage and coastal construction management. The variability of wave height is influenced by seasonal, annual and inter-annual changes in atmospheric and ocean variability such as ENSO or the other teleconnections. However, it is difficult to qualify the relation between wave climate and climate variability due to lack of data. This study analyzes monthly wave height variabilities considering local generated waves and remote swells based on statistical analysis by principal component analysis and multi-linear regression method using atmospheric analysis data, wave hindcasts and observations. The spatial and temporal characteristics of monthly wave heights are obtained around Japan.
