Temporal evolution of the 2D density distribution for a CW–CH interaction with a realistic density profile that includes a depleted (blue vertical structure) and an enhanced wave part (red vertical structure), and four different incident angles, α₁ = 80°, α₂ = 70°, α₃ = 65°, and α₄ = 55°. Note: the temporal evolution shown in the last panel can also be seen in Movie 2, which accompanies this paper.
