THE NEAR-SURFACE LAYER OF THE OCEAN
used the deeper part of the experimental profile. (This constant would be
smaller if we used the near-surface part of the profile.)
Figure 3-18 shows the COARE data scaled according to the Terray et al.
(1996) variables z H s and HH s /F 0 . The CB94 model (3.44) with z 0
parameterized according to (3.47) and with the turbulence flux of the kinetic
energy expressed with (3.35) reads in dimensionless coordinates

roughness length: (a) formula (3.46) for a C = 90,000, (b) formula (3.47) with c T = 0.6. Thin lines
represent the 95% confidence intervals. The vertical dashed line is the logarithmic layer model.
The bold dashed curves are the Craig and Banner (1994) model (3.45). Adapted from Soloviev
