The time averaged (from day 0 to day 10) power spectrum analysis in (a) the left and (b) the right singular vectors and (c) the corresponding singular values in the TLM that evolves a perturbation at a time step to . Note a singular value on the -axis right panel is a linear perturbation growth rate when the perturbation is grown linearly for 12 hours.
