Abstract

In this study, the peak wave period Tp and mean wave period T02 and Tm1,0, which are major parameters for classifying ocean characteristics, were calculated using water surface elevation data observed from the second west coast oceanographic and meteorological observation tower. In addition, the ratio of abnormal data, correlation analysis, and optimal probability density function were estimated. In the case of Tp among the calculated representative periods, the proportion of abnormal data was 5.73% and 0.67% at each point, and T02 was 4.35% and 0.01%. Tm1,0 was found to be 2.82% and 0.03%. Meanwhile, as a result of analyzing the relationship between T02 and Tp, the relationship was calculated to be 0.53 and 0.63 for each point. The relationship between Tm1,0 and Tp was 1.15 and 1.32, respectively, and T02, Tm1,0 was 1.18 and 1.22. As a result of estimating the optimal probability density function of the calculated representative period, Tp followed the ‘Log-normal’ and ‘Normal’ distributions at each point, and T02 was ‘Gamma’, ‘Normal’ distribution and Tm1,0 showed that ‘Log-normal’ and ‘Normal’ distribution were dominant, respectively. It is decided that these results can be used as basic data for wave analysis conducted on the west coast.
