The energy dissipation rate is an important characteristic of turbulence; however, its magnitude in observational profiles can be misidentified owing to its erratic evolution. By analysing observed data from oceanic turbulence, we show that the vertical sequences of depth-averaged energy dissipation rates have a scaling property. Subsequently, we propose a method to estimate the energy input rate by utilising this property. For scaling in the observed profiles, we show that our data have a… 

The use of tidally induced vertical-mixing schemes in simulating the Pacific deep-ocean state

AbstractEstimation of turbulence intensity with a fast-response thermistor is examined by comparing the energy dissipation rate from a Fastip Probe, model 07 (FP07), thermistor with from a shear

Decay of Turbulence in the Upper Ocean following Sudden Isolation from Surface Forcing

Measurements of velocity, hydrography, surface meteorology, and microstructure were made through several squall events during a westerly wind burst that occurred in the Western Pacific warm pool in

Direct numerical simulations of passive scalars with Pr>1 advected by turbulent flow

Direct numerical simulations of passive scalars, with Prandtl numbers Pr=3, 5, and 7, advected by turbulence at three low Reynolds numbers were performed. The energy spectra are self-similar under

Global Patterns of Diapycnal Mixing from Measurements of the Turbulent Dissipation Rate

The authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect

Batchelor's theory of the turbulent straining of small‐spatial‐scale amplitude variations of a convected scalar field is re‐examined to see the effects of fluctuation of the rates of strain in space
