Modelling probability distributions of the dissipation rate

Editor’s Highlight—

 

The authors of this paper are among the few oceanographers who have mastered the complexities of stratified turbulent transport processes. This paper presents an analysis of observations of turbulent energy dissipation obtained from vertically profiling instruments. The authors discuss the observations in terms of cumulative probability distributions and address the issue of the log-normality of dissipation. They report significant deviations from log-normality in oceanic regions where stratification is important and find the Burr type XII distribution to provide a better fit over a wide range of conditions. Given that the motivation for a log-normal distribution was first discussed by Kolmogorov nearly 70 years ago, this paper is a potentially significant contribution.
