Initial conditions for a 2D case of CW–CH interaction with a realistic density profile for the incoming wave (ρ_IAE = 1.1, ρ_IAD = 0.8, w_E = 0.1, w_D = 0.2), constant CH density (ρ_CH = 0.1), and four different incident angles (α₁ = 80°, α₂ = 70°, α₃ = 65°, and α₄ = 55°.). The corresponding time-distance plots for this interaction are generated along the depicted paths (path 1, path 2, and path 3).
