波增长的测量表明，主要由输入从大气，非线性传输到较短和较长的波，平流的波谱的能量平衡。取限谱的显著谱峰和尖锐的低频截止特性被解释为非线性波-波相互作用的自稳定特性。从大气传递到风浪的动量占风阻力的很大一部分。这些研究结果是相关的微波遥感海面的后向散射和被动辐射测量方法。
Measurements of wave growth indicate an energy balance of the wave spectrum governed primarily by input from the atmosphere, nonlinear transfer to shorter and longer waves, and advection. The pronounced spectral peak and sharp low frequency cut-off characteristic of fetch-limited spectra are explained as a self-stabilizing feature of the nonlinear wave-wave interactions. The momentum transferred from the atmosphere to the wind waves accounts for a large part of the wind drag. These findings are relevant for remote microwave sensing of the sea surface by backscatter and passive radiometry methods.
