Altitude profiles of perturbed current density driven AW and GW wave modes and are displayed in panels a and b, respectively. ${\text{j}}_1^{\parallel }$, ${\text{j}}_1^{\text{p}}$, and ${\text{j}}_1^{\text{H}}$ are field-aligned, Pedersen, and Hall components of the current density. j₁ refers to the total current density magnitude. Input parameters are τ = 4.2 min, λ_h = 80 km, $k_z^l=0.11$ km⁻¹, and c_p = 321 m s⁻¹ for AW mode and are τ = 39.4 min, λ_h = 210 km, $k_z^l=-0.07$ km⁻¹, and c_p = 89 m s⁻¹ for GW mode.
