Abstract

Estimates of the latent heat flux at the air-sea interface made by the profile method are compared to estimates by a wind-wave interaction (WWI) method that takes into account both wind and wave characteristics. A data set that consisted of profile measurements (six levels) of wind, temperature, and humidity over the Arabian Sea was used to compare the methods, and the agreement is good. It is shown that this WWI method can be used to compute the shear velocity, and then the results can be applied in the computation of latent heat flux. The parameters used in the WWI method are wind speed and direction, air temperature and humidity, sea-surface temperature, and significant wave height and period. All these data may be obtained from standard ship observations.
