FIGURE 14.1. Relations between the
power spectrum of rolling gusts and the point spectrum of turbulence
for various values of the ratio of scale of turbulence to wing span.
(a) Ratio of power spectrum of rolling gusts to point spectrum of
turbulence versus reduced frequency as conventionally plotted on
log-log scales (top). (b) Square root of 
as a function of frequency plotted
linear scales (bottom).
