Development and Decay of Temperature Gradients in the Surface Layer During Phases A and A1 MILOC 65.

Abstract

The meteorological data collected on passage between OWS KILO and OWS JULIET in the summer of 1965, during the MILOC 65 survey, are converted into total heat flux at the sea surface, vertical momentum flux, and evaporation rate. A simplified model for the first 0.5 mm of the sea surface is proposed in order to compute the density changes of the surface water caused by evaporation and heat flux; these density changes are considered to be a measure of the intensity of the thermohaline convection. The results obtained by means of this model together with the vertical flux of momentum are compared with the temperature differences between the sea surface and the 5 m depth level. The data suggest that the development and decay of these temperature differences follow the behaviour of the momentum flux as well as the density changes of the surface water. (Author)
