预测风驱动的重力-毛细表面波从光滑态向波纹态的转变，仍是非线性波力学中的一个长期问题。通过求解受驱动耗散的非线性势流方程，我们将波长为4-13厘米的这些波映射到雷诺数-波能量相空间中。我们识别出一条分隔光滑态与波纹态波的转变带，在该带内，波陡度对雷诺数呈现非单调依赖关系。次谐波（不）稳定性分析表明，增长最快的模态会加剧载波波交替面上的波纹，这为界面图案形成及海洋遥感提供了具有广泛意义的见解。
英文摘要
Predicting the transition of wind-forced, gravito-capillary surface waves from smooth to corrugated states remains a longstanding problem in nonlinear surface wave mechanics. Solving driven-dissipative, nonlinear potential flow equations we map these waves ($4-13$ cm) onto a Reynolds number -- wave energy phase-space. We identify a transition band separating smooth from corrugated wave states - the wave steepness exhibits a non-monotonic dependence on Reynolds number within this. Subharmonic (in)stability analysis reveals that the fastest-growing mode intensifies corrugations on alternate faces of the carrier wave. Our results offer insights into parasitic capillary wave formation on steep carrier waves and are of interest to ocean remote-sensing.
