摘要
本文分析了在8114号台风的影响下石臼所海区波浪特征的变化,采用了两种分析方法:(1)统计方法;(2)谱分析方法。结果表明:(a)在台风的影响下,尽管在观测区域内风速风向变化不大,但波浪特征在不断随时间发生变化;(b)用两种方法得到的分析结果比较一致;(c)由谱分析方法计算的结果一般都大于由统计方法得到的计算结果;(d)谱峰周期和谱的重心坐标对应的周期比较稳定。
This paper analyses wave characteristics in the sea area of Shijiusue under the influence of the typhoon NO. 8114. The analysis is made with (1) statistical method and (2) spectral analysis method. The results indicate: (a) The wave characteristics vary with time under the steady wind field. (b) The results oftained with the two methods are consistent. (c) The numerical values of the wave characteristics calculated with the spectral method are lizger than those the statistical method. (d) The periods of the spectral peak and the spectral barycenter are steady.
