Imposes eddy viscosity and diffusivity characteristic of internal wave activity and shear instability when there is extinction of turbulence as suggested by Kantha and Clayson (1994). In this case, the new values of and , defined in (45), are used instead of those computed with the model.
When k is small (extinction of turbulence, diagnosed by klimiw), and are set to empirical values typical in the presence of internal wave activity (IW) and shear instability (SI). This model is described by
