Abstract
Eddy correlation measurements of vertical turbulent fluxes made during AMTEX 1975 are used to assess the reliability of flux prediction from established bulk transfer relations, using both surface-layer and planetary boundary-layer formulations. The surface-layer formulae predict momentum and latent heat fluxes to an accuracy comparable to the direct eddy correlation method, using transfer coefficients of C DN (at 10m and in neutral conditions) increasing with wind speed, and a constant C EN ∼- 1.5 × 10 −3. The data suggest C CHN , for sensible heat, increases significantly with wind speed and is on average 30% lower than C CEN The boundary-layer drag coefficient, C GD , agrees within about 40% of recently published values using a vertically averaged geostrophic wind to the height of the lowest temperature inversion, corrected for trajectory curvature. Values of θ * /δθ from which C CGH is derived, are in excellent agreement if the published values are modified to account for inappropriate surface temperatures used in their derivation. Preliminary values of C GE are also presented.
