Fig. 2From: On a numerical model for extracting TKE dissipation rate from very high frequency (VHF) radar spectral widthPlot of the TKE dissipation rate \(\varepsilon\) against \(\sigma\) (left) and the corresponding buoyancy length scale 1/kB (right). Cyan circles show the UAV-measured \(\varepsilon\) plotted against radar-determined \(\sigma\) for all 16 flights made during the ShUREX 2016 campaign. The blue line shows the numerical model (Eq. 54). The red line shows the Weinstock (1978, 1981) formulation, while the black line is the Labitt formulation. The magenta line corresponds to Eq. (55) with L = 25 m (see text). The green and magenta lines nearly overlap. Chen (1974) and other data cited in Fig. 2 of Weinstock (1981) are shown by filled red polygons. The units and the figure aspect ratio are selected to be similar to that in Figure 2 of Weinstock (1981) for easy comparisonBack to article page
