From the mesurement of wind-driven current in shallower part of Lake Biwa, itwas verified stable stratification makes the current profile significant. Another effectof stratification is the deflection in the surface current. Considering that these factsare explained as the reduction of the eddy viscosity, the basic effect of the Ekmannumber was detected in pipe flow experiments. Eddy diffusivities were evaluatedfrom the field data and the profile of the coeficient in neutral case and the variationdue to the temperature stratification. Estimating the surface Rossby number R*=u*/fL, significant deflection occurs arround R*=10, where L is the Monin-Obukhovlength, f Coriolis parameter. The destratification is regarded as a typical en-trainment process to the neutral state, on which the deflection occurs. The resultssuggest diurnal patterns of diffusion exist in lakes.
