Abstract

Temperature fluctuations due to the interfacial waves were measured in a shallow lake within the range the between basic internal wave of buoyant frequency and the surface wind ripple. The frequency spectrum shows an inertial subrange. These waves are generated from amplified internal wave, and wind waves bring similar structure on the interface through the resonance mechanism with much slower interfacial ones. Diffusivity takes the peak at the bottom of the interfacial layer, and for such diffusivity profiles, the log+linear law for temperature is retained. Considering the first few mode of cellular motion, the fluctuation of buoyancy in vertical was found to be similar with the measured one.
