Characteristic amplitude of all the thermodynamic fluctuations for the runs with M ~ 0.5 (hydro and f = 0.1) and M ~ 0.75 (cf. Fig. 8). In significantly turbulent atmospheres, p-waves start to affect the fluctuations dynamics via δP/P, still in conjunction with entropy perturbations (ω_turb is not yet ≫ω_BV). The derived quantities follow from the adiabatic/isothermal mode for the hydro/conductive flow.
