黄海海浪天气时间尺度变化的数值模拟研究
Numerical study on the variability of wave height on the weather time scale in the Yellow Sea
摘要
Abstract
Satellite observations indicate that the significant wave height (SWH) in the Yellow Sea (YS) exhibits significant variations in periods shorter than 12 days.The current study intends to investigate in detail the characteristics of the temporal and spatial variations in the weather with respect to the SWH in the YS as well as the associated dynamic processes based on Simulating WAves Nearshore (SWAN),a third-generation wave model.The results indicate that the strength of the weather variations in the SWH (denoted as Sw) shows strong characteristics in its temporal variations and spatial distributions.There is a high-value tongue of Sw extending from the south to north in the eastern-central part of the YS.Meanwhile,Sw decreases shoreward.It is largest in winter and smallest in summer.From November to May in the following year,the monthly climatology of Sw shows a spatial distribution similar to that of its annual mean.From June to October,however,there is a strong gradient in the monthly climatology of Sw perpendicular to the border between the YS and the East China Sea.Further analysis indicates that the Sw in the YS is dominated by windsea,with secondary contributions from swell.Numerical experiments prove that the weather variations in the SWH are caused by wind forcing with longer periods via four-wave nonlinear interactions.关键词
