An Investigation of Electro-Optical Turbulence Parameters.

Abstract

Mean humidity, temperature, wind data and fluctuating temperature and velocities data obtained from the R/V Acania were interpreted on the basis of empirically derived expressions describing the temperature structure parameter, (C sub T) squared, and the dissipation rate of turbulent kinetic energy, epsilon. Properties of (C sub T) squared and epsilon are related to a stability parameter Z/L and the Richardson number, Ri. Non-dimensional temperature structure functions parameters, (C sub T) squared Z to the 4/3 power (partial deriv. of theta with respect to Z) squared and turbulent kinetic energy dissipation rates, (Kepsilon ZU*) to the (-3) power, versus Ri were examined for open ocean conditions. This experiment verified earlier hypotheses that the profiles obtained from empirically derived expressions using overwater data are very much different from those obtained using overland data. The distribution of the non-dimensional turbulent kinetic energy dissipation rate agreed with that predicted by similarity theory. (Author)
