During a month, wave observation was characteristic of Suyeong bay since 16th of July. During the period, typhoons which were Ma-on, Muifa landed on Suyeong bay. Observation point places a half-way point between Gwangan light beacon in the utmost bounds of the west and Haeundae floating buoy in east.
To investigate the characteristic, using meteorological data not in just Gwangan light beacon but in Haeundae floating buoy. Through the spectrum analysis, we have confirmed the features of wave distribution on wave directions part.
Just as we meant, the changes of wave caused by direction of the wind have been turned out to be two main wind directions. It shows that the bigger the differences between two wave directions were the higher wave heights were. It means that changes of wave direction could cause high waves. Due to the result like these, we need to inquire to other typhoons. In the case of Suyeong bay, it would be necessary to study effects of river discharge on wave characteristic of the inside of a bay.
