摘要
根据1960～1989年南麂海洋站的实测风浪资料,分析了该海域的风浪特征,结果认为:这个海域的浪通常是混合浪,常见浪是三级波高的浪;海浪要素的均值分布比较平稳,极值具有不均匀分布的特性.本区的波高和周期的联合分布表明,波高在0.5～1.9m,周期为4.0～6.9s类型的浪在该海域出现频率最高.此外,引用最大熵谱方法找出了本区波高、周期和风速的主要变化周期.还讨论了台风浪的周期与最大波高的经验关系.
According to observational data during 1960-1989 at Naji Oceanographic Station, the characteristics of wind and wave in the area are analysed. The results show the wave in the area is usually mixing type with wave height often being force-three. The mean distribution of wave elements is smooth while the distribution extremes uneven. The union distribution indicates that the frequency peak of occurrence falls on the kind of wave of 0. 5~1. 9m in height, 4. 0 - 6. 9s in period. The basic change cycle about wave height, period and wind speed is obtained using the method of largest entropy spectral analysis. The empirical relationship between period and largest wave height of the hurricane wave is discussed.
