HaraFunding is provided to develop a new model of air-sea momentum flux at high sea states including the enhanced drag by breaking waves. The central hypothesis for the work is that the momentum flux is a sum of the contribution by non-breaking waves (estimated by integrating the wave drag due to each sinusoidal component), the contribution from breaking waves (estimated by integrating the drag per unit length of breaking wave crests), as well as skin friction. Both filed and laboratory observations will be used to test the model. The parameters in the model will be adjusted to represent realistic open ocean surface wave spectra and breaking wave statistics.

利用HaraFunding建立了一个新的海气动量通量模式，该模式考虑了破碎波对海气动量通量的影响。这项工作的中心假设是，动量通量是非破碎波(通过积分每个正弦分量的波阻估计)、破碎波的贡献(通过积分单位长度的破碎波峰的阻力估计)以及表面摩擦的总和。现场观测和实验室观测都将用来检验该模型。模型中的参数将进行调整，以代表真实的开阔海面波谱和破碎波统计数据。
