應用電腦數值模擬的方式，本報告先模擬出具不同群高因子(GHF)及群長因子(GLF)的群波，接著探討GHF 及GLF 等兩個群波因子，對波浪的波高—週期聯合分佈，及波高與週期相關係數之影響，其中數值模擬時採用的波浪水位能譜為JONSWAP 頻譜。本文的研究結果顯示，大致上，GHF 較大及GLF 較小時，波高與週期的相關係數會較大，即較相關。 The method of numerical simulation is used in this report to simulate the wave groups. Then the effects of GHF and GLF of wave groups on the joint probability density function (JPDF) and the correlation coefficient of wave heights and periods are investigated. The JONSWAP spectral model is adopted as target spectrum. The final results show that the larger GHF and smaller GLF will have the larger correlation coefficient.
