of initial disturbances will probably have a greater influence on the scale of the developed eddies than the scale of the fastest growing linear mode.

the initial disturbances more effectively.
Think of the root of the tree as
the initial disturbance, and the ground as an initial time point.
Lets imagine that there is a positive feedback that in the secondary effect increases
an initial disturbance by 50 %.
