摘要
基于MIKE21 SW波浪数值模型,结合莱州湾海域地形、波浪特点,以莱州气象站的风速资料为基础,对莱州湾海域的设计波浪要素进行模拟和分析。与海上测风塔实测波浪要素进行了对比,验证了模型模拟的准确性和可靠性,并对计算方法和模型的适用性进行了探讨。结果表明:莱州湾海域波浪从湾外向近海传播,受海底地形、岸线走向、风速风向的影响,波浪发生一定的折减、绕射等衰减现象,波浪场的分布特征与风速风向、水深、地形密切相关。研究成果可供莱州湾海上风电的开发利用借鉴参考。
According to the wind speed data provided by Laizhou meteorological station,and by incorporating the characteristics of topography and waves of Laizhou Bay,we simulated and analyzed the designed wave parameters based on MIKE21 SW wave numerical model.By comparing with the wave parameters measured by the offshore wind tower,the model's accuracy and reliability is verified.We also discussed the calculation methods and the model's feasibility.The results show that waves spread from outside of the bay to the inshore waters;under the effects of seabed terrain,coastal line,and wind speed,sea waves show an attenuation of reduction and diffraction;the distribution of the wave fields is closely related to wind speed,water depth and terrain.The research results can provide reference for the development and utilization of offshore wind power.
