Abstract : The considerable number of physical processes which take place over a water surface and which are the result of the interaction between the water and the atmosphere, to a great degree is determined by the intensity of the turbulent mixing over water. Such, for example, are the processes of heat exchange and moisture exchange between the water and the atmosphere, drift currents, and others. Despite the great significance of these processes for various branches of the national economy, turbulence over seas has been investigated relatively little. Below are presented certain results which are a definite contribution to existing data on turbulence over a water surface. The most important characteristic of turbulence over a water surface is the coefficient of turbulence in the vertical. As is generally known, this coefficient applies to formulas for the calculation of heat and moisture fluxes, momentum, and other factors. By having available in each of the experiments, data on the temperature lapse rate and the wind speed it is possible to determine the relationship between the turbulence coefficient and the usual meteorological characteristics over a water surface. Of such a type were the data of 54 experiments which were processed and analyzed. (Author)
