Observations in wind-wave flumes have shown that the presence of low frequency (LF) paddle waves influences the evolution of high frequency (HF) wind-waves (Mitsuyasu, 1966). This includes observed suppression of HF waves in the presence of LF waves following the wind (Donelan, 1987;Hatori et al., 1981;Mitsuyasu, 1966), and observations of opposing LF waves enhancing the wind-generated HF waves (Mitsuyasu & Yoshida, 1989). This process is important for modeling wind-waves and their interaction with swell. The prominent wind-wave theories however do not address this behavior; and there is no clear consensus on the physical mechanisms proposed to explain this effect (Donelan et al., 2010;Mitsuyasu, 2015;Mitsuyasu & Yoshida, 2005). As a result, minimal consideration is given to this process in contemporary wind-wave models such as SWAN (Booij et al., 1999). Only one relatively new source term package, ST6 (Rogers et al., 2012;Zieger et al., 2015), compensates in part for the suppression of HF waves by LF waves, which as a new model, likely requires further testing, validation, and refinement. In the ocean, LF waves are known to modulate radar backscatter from the ocean surface, which is primarily coupled to HF waves. This effect is partly caused by LF waves physically modulating the intensity
