Abstract：The Coupled Ocean-Atmosphere Response Experiment (COARE) algorithm is the more advanced algorithm in the world for the air-sea flux.The newest COARE 3.0 algorithm includes two sea surface aerodynamic roughness schemes with consideration of specified wave properties named TY01 and O02.When lacking significant wave height and dominant wave period,the COARE 3.0 algorithm will use Taylor01 scheme to parameterize them.In this paper,we introduce our new developed Wind-wave significant wave Height and dominant wave Period (WHP) parameterization scheme and three sea surface aerodynamic roughness schemes named SCOR,GW03 and PYP07,in addition,two simple friction velocity algorithms named Andreas 12 and Vickers 15 are introduced.Using buoy data and the sink data,we compare above schemes for the moderate to high wind speeds.Results show that:the application of WHP scheme in COARE 3.0 algorithm is better than Taylor01 scheme,three new introduced sea surface aerodynamic roughness schemes named SCOR,GW03,PYP07 have smaller error and higher stability;the calculated friction velocity by WHP scheme combined with SCOR sea surface roughness scheme is the most close to the measured sink values;the test results used the additional introduction of the other three kinds of measured data show that the original COARE 3.0 algorithm will underestimate friction velocity,while the WHP scheme combined with SCOR sea surface roughness scheme can more accurately predict the growth trend of friction velocity over 10m wind speed.
