摘要
利用东矶列岛海域一年实测波浪资料,统计分析波要素特征,以台风“利奇马”为例,分析台风浪演变过程。结果表明:研究海域年平均有效波高0.88 m,年平均周期4.3 s,年最大波高8.67 m出现在夏季台风“利奇马”影响时。研究海域以轻浪为主,其次是小浪和中浪;常浪向为ESE,次常浪向为E和SE;强浪向为SSE,次强浪向为SE。波浪平均持续时间和波高之间符合指数衰减关系。台风“利奇马”影响期间,最大谱峰56.20 m2/Hz,台风浪谱型以双峰谱为主,台风浪类型经历了涌浪—混合浪—风浪—混合浪—涌浪这一演变过程。
Utilizing one year of measured wave data in the Dongji Islands sea area,this study statistically analyzes wave characteristics and examines the evolution of typhoon waves,taking Typhoon"Lekima"as an example.The results indicate that the annual average significant wave height in the study area is 0.88 m,with an average period of 4.3 s.The maximum wave height of 8.67 m occurred during the impact of Typhoon"Lekima"in the summer.Light waves dominate the study area,followed by small and medium waves.The prevailing wave direction is ESE,followed by E and SE;the strong wave direction is SSE,followed by SE.There is an exponential decay relationship between the average wave duration and wave height.During the influence of Typhoon"Lekima,"the maximum spectral peak reaches 56.20 m²/Hz,and the typhoon wave spectrum is characterized by a double⁃peak pattern.The typhoon wave type undergoes the transition of swell to mixed waves to wind waves to mixed waves to swell.
