(color online) The evolutions of the normalized amplitudes of (a) the fundamental mode , (b) the second harmonic , and (c) the third harmonic for mode number and 30, respectively. The RTI growth is perturbed by both interface and velocity perturbations with for A = 1. The planar results (dotted)^[20] are plotted for comparison.
