Effect of Sampling Rate and Random Position Error on Analysis of Drifter Data
Sampling Rate Drifter Data Random Position Error
2009/2/13
The central question discussed here is how the rate at which drifter positions are determined and the position errors affect the calculation of velocity, acceleration and velocity gradients such as di...
Sampling Turbulence in the Stratified Ocean：Statistical Consequences of Strong Intermittency
Stratified Ocean Statistical Consequences Strong Intermittency
2009/1/8
Turbulence and turbulent mixing in the ocean are strongly intermittent in amplitude, space and time. The degree of intermittency is measured by the “intermittency factor” σ2, defined as either σ2ln, t...
Recently it has been argued that in many regions of the ocean the Osborn–Cox model accurately determines the total long-term diapycnal flux of a tracer θ if the mean gradient and dissipation in the mo...
