Abstract
On the basis of radiometric measurements of thermal radio emission from water at wavelengths 2.3 and 5 mm, we study the dynamics of heat and mass transfer through a water-air boundary, which is related to atmospheric turbulence, and reconstruct the behavior of the water-temperature profile and the heat flux through this boundary. The heat-flux components due to evaporation and thermal conductivity and the evaporation rate from unit surface are determined. Turbulence-induced variations in the depth of the atmospheric viscous sublayer are studied. Statistical parameters of the water-surface temperature variations are calculated. We find that these variations were much greater than the turbulent fluctuations of the air temperature under the measurement conditions.
