Abstract :A storm surge of the typhoon 0423 generated bay undulations in Japan on October 20-21,2004 and the bay undulations were analyzed using the records observed at 9 tide stations during one day from 12:00(JST) on October 20. The sea level deviations from the ordinal levels were decomposed into amplitude apectra for every 6 hour with overlapping of 3 hours. Noticing the dominant periods we examined a relation between the dominant period and the wind direction, and summarized that the bay undulations are excited by the wind parallel to the bay direction and the amplitude increases with the duration time but not depends on the wind strength. The straight bays tend to show a rapid response to the wind direction.
