Nakai and Hashimoto(2008) defined "longevity of infragravity waves" and showed characteristics of longevities of various frequency components in The Pacific Ocean and The Sea of Japan. And they showed that the longest component whose period is more than 600s sometimes develops even when shorter components and wind waves do not develop. In this paper, we calculated longevities of wind waves and compared them with those of infragravity waves. And we analyzed the relationship between development of the longest component of infragravity waves and the atmospheric pressure. When the longest component starts developing, the atmospheric pressure starts decreasing in the synoptic scale and the variation of atmospheric pressure whose period is less than one hour increases at the same time.
