Characteristics of Waves Continuously Observed over Six Years at Offshore Central East Coast of Korea

摘要

This study presents the results of analysis for the wave data that were consecutively collected from February 2013 to November 2018 at the location of 1.6 km offshore from Namhangjin beach.The water depth at the location is 30.5 m and waves were measured by AWAC (Acoustic Wave And Current meter).By using wave-by-wave analysis and spectral analysis,wave heights and periods were evaluated and then the relationships between the quantities obtained by the two methods were proposed based on linear regression analysis.In addition,monthly and yearly variations of the significant wave height and period,and the peak wave direction were analyzed.Moreover,the relationship between the significant wave height and period was newly suggested.Variability and probability distribution of the significant wave period with respect to the significant wave height were also examined.
