Abstract
Based on the measurements from the US National Data Buoy Center 3-m discus buoy site No. 44004 (38.5°N, 70.47°W) from January 1 to March 31 of 2003, with the COARE algorithm (Version 3.0), the results from four parameterization schemes developed recently for sea surface aerodynamic roughness length were compared with each other. Calculations of frictional speedu*, drag coefficientC d and wind stress τ indicate that the calculated frictional velocities from the four schemes (8.50%–16.20%, the normalized standard error estimate, or NSEE), the computed drag coefficients and wind stress (respectively 15.08%–28.67% and 17.26%–50.59% NSEE) are reasonable. Schemes YT96 and GW03 are consistent. The O02 scheme gives over-estimated values foru* andC d. Schemes TY01 and GW03 display discontinuous characteristics in handling young wave data.
