(a) Snapshot of fractional density fluctuation δρ/ρ in the meridional plane. (b) Growth rate of parametric decay instability (PDI) (γ_PDI/2, solid line) in units of mHz and the magnitude of density fluctuation (δρ_rms/ρ, dashed line) vs. radial distance. (c) Reflection rates of antisunward Alfvén waves ω_ref with and without density fluctuations. The animation of panel (a) runs from simulation time, τ = 0 to 50 minutes, where τ = 0 is when the system reaches a quasi-steady state.
