有效波高、平均周期和峰频率确定的JONSWAP谱

JONSWAP Spectrum Decided by Significant Wave Height,Average Period and Peak Frenqency

本文提出根据实测的有效波高H、平均周期T和峰频率ω_0确定JONSWAP谱的变分原理。应用这一变分原理导出的JONSWAP谱,其峰频率为ω_0,而且满足关系式,或。

Based on measured significant wave height H, average period T and spectral peak frenquency ω0,the variational principle of JONSWAP spectrum is decided. By using the principle, JONSWAP spectrum is derived whose spectral peak frequency is ω0 and satisfies the equations:H=4.0 mo^(1/mo) ,T=2π(m0/m1) or T=2π
