Addendum to `Wind Stress Over Waves: Effects of Sea Roughness and Atmospheric Stability’

Myrhaug and Slaattelid 1 (hereafter referred to as MS) considered the effects of sea roughness and atmospheric stability on the sea surface wind stress over waves, which are in local equilibrium with the wind, by using the logarithmic boundary layer profile including a stability function, as well as adopting some commonly used sea surface roughness formulations. The engineering relevance of the results was also discussed. Since no consistent sea surface roughness formulations existed in the literature at that time, MS chose to demonstrate how the results varied by using two roughness formulas having significantly different behavior. MS used the Toba et al. 2 formula where the roughness increases as the wave age increases, and the Donelan et al. 3 formula where...
