Abstract

As the characteristics of infragravity waves are different depending on the frequencies and the sea areas, it is presumed that the mechanism of generation and development of each frequency component in each area is different. We analyzed wave height data of four components (30 - 60 s, 60 - 300 s, 300 - 600 s and 600s -) of infragravity waves compiled by the NOWPHAS (Nationwide Ocean Wave information network for Ports and HArbourS) system of Japan to get information on generation and development of each component. This study reveals that the spectral characteristics of the time changes of the longest component (600s-) are very different from those of the shorter components and that development of the longest component has very much to do with the barometric depression.
