本研究描述了一个菲利普斯的Λ（c）分布模型，这是破碎锋（每单位表面积）的预期长度以速度c到c+dc移动，提供了一个框架耦合大气-波浪-海洋模型，以明确说明波浪破碎相关的海气通量。Λ的模型取决于光谱饱和度，基于超过波斜率标准的波峰长度的高斯统计，以及长波-短波调制。在模型WaveWatchIII中实现了基于Λ的波浪破碎耗散函数。波解与观测结果一致，包括谱和Λ（c）分布的几个度量。从Λ得到的白浪覆盖再现了最近在大风时饱和的参数化。由于波流相互作用引起的波浪破碎变率在亚中尺度（1 km或更小）是显著的。波破碎模型可以进一步发展到模拟气体传输系数和气溶胶的产生。
This study describes a model of Phillips' Λ(c) distribution, which is the expected length of breaking fronts (per unit surface area) moving with velocity c to c+dc, providing a framework for coupled atmosphere‐wave‐ocean models to explicitly account for wave breaking related air‐sea fluxes. The model of Λ depends on the spectral saturation, based on Gaussian statistics of the lengths of crest exceeding wave slope criteria, and long wave‐short wave modulation. A wave breaking dissipation function based on Λ was implemented in the model WaveWatchIII. The wave solutions are consistent with the observations, including several metrics of the spectrum and Λ(c) distributions. The whitecap coverage derived from Λ reproduces recent parameterizations saturating at high winds. The wave breaking variability due to wave‐current interaction is significant at submesoscales (order 1 km or smaller). The wave breaking model can be further developed to model gas transfer coefficients and aerosol production.
