- Insist about open data and availability of spatiotemporal spectra
- Insist about open data and availability of many different types of outputs
and in particular spatiotemporal spectra
- Insist on the large number of simulations (spanning the (Fh, R) space). Show
what is available in the literature.

- Strong "negative" result: if we do not change the equation, even by forcing
very gently IGW, we do not obtain a statistically stationnary state
corresponding to a "pure poloidal strongly stratified turbulence".
- Is the buoyancy Reynolds number important for stratified turbulence forced by
waves? Is there a transition for small R? Is there a "viscosity affected
regime" for this forcing? If yes, how is it similar/different than the
"viscosity affected regime" for forcing with vortices?
- forcing by waves: transition between "viscosity affected regime" to a
non-linear regime. No weak turbulence regime. (?)
- Only waves for small k_z can be weakly nonlinear. (?)
- First clear observation of the F_h^-1 scaling (data in Garanaik &
Venayagamoorthy (2019) not very convincing)
- Bottleneck à k_b in E_vort(k_h).
