田辺湾の長期波浪特性に関する研究

抄録

We have observed waves, tide, winds and temperatures at the tower named Tanabe-Nakajima Storm Surge Observation Tower standing at the mouth of Tanabe-Bay in Wakayama Prefecture. After removing many kind of noise in the original data by a special filter, significant wave heights and periods are calculated from Dec. 1994 to Aug. 1999. Comparing between wind and wave conditions, characteristics of seasonal and yearly variations are analyzed. In winter season, wind waves are dominant and there is an upper criterion of wave height restricted from wave slope. In summer season, swell become predominant. Yearly maximum wave heights are generated by typhoons so that the yearly variation is bigger than mean seasonal one.
