Analysis of the characteristics of typhoon waves in the Yangjiang sea area,Guangdong
摘要
Abstract
Based on seven sets of measured typhoon wave data in the Yangjiang sea area,the characteristic values of typhoon wave parameters are calculated,and the characteristics of the typhoon wave process and spectrum are analyzed.The results indicate the following:(1)Typhoon waves in the study area are significantly influenced by the typhoon grade and path.The stronger the typhoon grade and the closer the distance,the more pronounced and in-tense the typhoon wave process,with higher wave heights and spectral densities.(2)The duration of the typhoon wave impact is approximately 3 days,during which the maximum wave height,spectral peak period,and spectral peak density exhibit a generally consistent trend of initially increasing and then decreasing.The maximum wave height lags behind the peak period by about 2-10 hours.(3)The wave spectrum is predominantly bimodal,with a small number of unimodal spectra observed.(4)The most significant impact among the seven typhoon waves is from Typhoon Ma-on,with a maximum wave height of 10.87 m and a spectral peak density of 53.79 m2/Hz.As Typhoon Ma-on approaches and strengthens to the typhoon level,a strong exponential relationship exists between the maximum wave height and the distance from the typhoon center.The maximum wave height increases signifi-cantly as the distance from the typhoon center decreases;the shorter the distance,the higher the wave height.These findings can provide valuable reference data for the design,disaster prevention,and risk reduction of offshore wind power projects in the Yangjiang sea area.关键词
