Coarse Grid Wave Hindcasting in the Yellow Sea Considering the Effect of Tide and Tidal Current

摘要

In the present study,wave measurements at KOGA-W01 were analyzed and then the numerical wind waves simulations have been conducted to investigate the characteristics of wind waves in the Yellow sea.According to the present analysis,even though the location of the wave stations are close to the coastal region,the deep water waves are prevailed due to the short fetch length.Chun and Ahn’s (2017a,b) numerical model has been extended to the Yellow Sea in this study.The effects of tide and tidal currents should be included in the model to accommodate the distinctive effect of large tidal range and tidal current in the Yellow Sea.The wave hindcasting results were compared with the wave measurements collected KOGA-W01 and Kyeockpo.The comparison shows the reasonable agreements between wave hindcastings and measured data,however the model significantly underestimate the wave period of swell waves from the south due to the narrow computational domain.Despite the poorly prediction in the significant wave period of swell waves which usually have small wave heights,the estimation of the extreme wave height and corresponding wave period shows good agreement with the measurement data.
