Pulsating turbulence in a marginally unstable stratified shear flow

Commonalities in the vertical structure and magnitude of ε are seen via scaling of ε by τ•Sh/ρ0, where τ is the surface wind stress, Sh is the mean value of Sh over the DC layer and ρ0 a mean water density.

“Commonalities in the vertical structure and magnitude of ϵ are seen via scaling of ϵ by τ •Sh/ρ 0 , where τ is the surface wind stress, Sh is the mean value of Sh over the DC layer and ρ 0 a mean water density (Smyth et al., 2017).”

The model of pulsating DC turbulence derived by Smyth et al. (2017) pertains to night-time only and was tested using data between 20 m and 70 m depth in a regime of exceptionally strong DC, November 2008 at 140W; in that case the scaled value was 0.86.
