...These are called absolutely unstable flows, as opposed to convectively unstable flows, which behave merely as disturbance amplifiers (Huerre & Monkewitz 1990), with the disturbance energy being convected away from the place it was created....

...That the stability operators are not self-adjoint implies that a superposition of stable eigenmodes can lead at early times to algebraic growth of the disturbance energy (see, e.g., Butler & Farrell 1992, Trefethen et al. 1993)....
