风浪谱模式初步分析

Preliminary Analysis on Wind Wave spectra

本文主要讨论分析了JONSWAP谱型模式和洪广文理论谱模式。对莆田、连云港风浪谱进行两种模式对比分析。结果表明:JONSWAP谱结果好于洪广文谱模式。洪广文理论谱模式中参数同波高、波周期分布参数不一致,理论上它们是相同的。文中给出了代表莆田和连云港两地风浪,JONSWAP谱型谱表达式。

The paper presented a comparative analysis result between JONSWAP Spectrum and a theoretical spectrum presented by Hong Guanwen by using the field wind wave data recorded in putian and Lianyungang. The results showed that JONSWAP Spectrum was in better agreement with field data than Hong's spectrum. It was found that the parameters in Hong's spectrum were inconsistant with the distribution parameters of wave heights and wave periods,eventhough theoretically they should be consistant. The paper presented the expression of JONSWAP Spectra which may represent the wind waves in Putian and Lianyungang
