Micrometeorological measurements, including direct eddy - correlation heat and moisture fluxes, have been made under light wind conditions in the western equatorial Pacific. The sea surface "cool skin" of about O.5°C was observed; air-sea temperature differences were 1-1.5°C larger than long term averages from merchant-ship data. Bulk transfer coefficients for both fluxes increased markedly as wind speed fell below 4 m/s, in excellent agreement with the predictions of Liu et al. (1979). Dissipation estimates of the fluxes are about half the covariance measurements below 4 m/s. Observations of the individual components of radiation suggest that commonly used empirical formulations overestimate both long - and short wave in this region by 15-20 W/m2. Application of all possible corrections would reduce Reed's (1985) estimate of net heat flux into the ocean by some 80 W/m2 to around only 20 W/m2 in this region of the Pacific. (Résumé d'auteur)
