Turbulent wind data measured in the atmospheric surface layer and wind tunnels are used to estimate the Kolmogorov constant Ck. The analysis discusses distinct procedures to obtain the mean energy dissipation rate and Ck. We find that for our datasets the most reliable method is the third-order...

The statistical properties of fully developed hydrodynamic turbulence can be successfully described using methods from nonextensive statistical mechanics. The predicted probability densities and scaling exponents precisely coincide with what is measured in various turbulence experiments. As a...
