It is reported that long-period waves with more than 30s wave period sometimes cause interruptions in marine works. The long-period wave could be induced by a typhoon, and the relations between long-period-waves and typhoons were examined. In this study, three parameters, maximum wind speed and ra-dius of strong wind area of a typhoon and propagation distance between typhoon location to observation point, were investigated as the dominant parameters to the long-period wave height at the observation point, and the estimation model of long-period waves were proposed. In the analysis, the propagation times from the typhoon location to the observation point were taken into account. As a result, the strong relation between the long-period waves and the three above-mentioned parameters was confirmed by con-sidering the propagation time. Among the three parameters, the propagation distances affect to the long-period waves the most. The possibility that long-period waves can be estimated with the three above-mentioned parameters was presented.
