| logical mom_bkgnd_mixing::bkgnd_mixing_cs::henyey_igw_background |
If true, use a simplified variant of the Henyey et al, JGR (1986) latitudinal scaling for the background diapycnal diffusivity, which gives a marked decrease in the diffusivity near the equator. The simplification here is to assume that the in-situ stratification is the same as the reference stratificaiton.

| logical mom_bkgnd_mixing::bkgnd_mixing_cs::henyey_igw_background_new |
same as Henyey_IGW_background but incorporate the effect of stratification on TKE dissipation, e = f/f_0 * acosh(N/f) / acosh(N_0/f_0) * e_0 where e is the TKE dissipation, and N_0 and f_0 are the reference buoyancy frequency and inertial frequencies respectively. e_0 is the reference dissipation at (N_0,f_0). In the previous version, N=N_0. Additionally, the squared inverse relationship between diapycnal diffusivities and stratification is included:
kd = e/N^2
where kd is the diapycnal diffusivity. This approach assumes that work done against gravity is uniformly distributed throughout the column. Whereas, kd=kd_0*e, as in the original version, concentrates buoyancy work in regions of strong stratification.
