Records of storm surge and secondary oscilations induced by Typhoon no.19,1991.
Typhoon No.19 attacked Japan in September 26-28th 1991, and caused severe disaster. Its magnitude has shown record figures such as atmospheric pressure low 935 Mb at landing on the Kyusyu. Its moving speed was very high and accompanied winds were very strong. Then,the typhoon caused severe storm surges in various coasts around the western area of Japan. In this paper, the storm surges which are shown in the records of tide gauges of the Hydrographic Department, are described. In 7 tide stations, the water heights at the storm surge exceed the former records. Comparing the times of the highest height and the lowest atmospheric pressure, they are not always matched and sometimes delayed, In some cases the highest heights occurred at the times of the winds blowing against the coasts and sea water piled up to the bays, and in another cases its occurred at the time of the returning uplift of water height induced by the secondary oscillation in the resurgence.

| Summary: | Typhoon No.19 attacked Japan in September 26-28th 1991, and caused severe disaster. Its magnitude has shown record figures such as atmospheric pressure low 935 Mb at landing on the Kyusyu. Its moving
speed was very high and accompanied winds were very strong. Then,the typhoon caused severe storm surges in various coasts around the western area of Japan. In this paper, the storm surges which are shown in the records of tide gauges of the Hydrographic Department, are described.
In 7 tide stations, the water heights at the storm surge exceed the former records. Comparing the times of the highest height and the lowest atmospheric pressure, they are not always matched and sometimes
delayed, In some cases the highest heights occurred at the times of the winds blowing against the coasts and sea water piled up to the bays, and in another cases its occurred at the time of the returning uplift of water height induced by the secondary oscillation in the resurgence. |
