Abstract

Abstract

Sea surface roughness derived from dimensional analysis bears a relation to wave age and swell. The paper explored two scalings parameterization schemes' sensitivity to wave age and wave steepness, concluded that the errors estimated from wave age scaling are lower from wave steepness scaling. Based on data of the six air-sea interaction experiments under different water depth, fetch and sea state conditions, we distinguished between two classes of sea state: pure wind sea or wind sea-dominant and swell-dominant,tested the suitability of the wave age and wave steepness scalings schemes under different experiments. It be found that wave age scaling have higher suitability than wave steepness scaling under variedly sea state conditions. For pure wind sea or wind sea-dominant cases, the calculated results based on PS07 and DGHQ03 are close to those given by the eddy correlation method, GW06 scheme secondly, O02 calculations are overestimated markedly. For swell-dominated sea cases the calculated results based on the two sea-state scalings are all underestimated. The errors of sea roughness based on O02 scheme is the least, the TY01 scheme lead to the maximum errors.
