| ABSTRACT |
|
Diverse statistical characteristic analyses, including distribution estimation, location differences, and monthly differences, were performed with emphasis using monthly frequency information for high waves and sudden high waves extracted from 17 years of wave observation data from seven stations along the East Sea coast. Overall, the Poisson distribution was identified as the most appropriate distribution for all locations, while the Zero-Inflated Poisson distribution was found to be a more suitable distribution for the Mukho station. Station differences were identified as distinct from other stations, with Mukho showing a clear distinction and being categorized into groups with relatively high and low high wave frequency. On the other hand, while distinct differences were observed in monthly frequency, the statistical confidence intervals were estimated to be substantial. As a result of analyzing the data by reducing the size of the confidence interval using a large sample dataset that integrates all locations, it was found that the frequency was below the average from May to August, April and September were at the average level, and the remaining periods showed an above-average frequency. |
