Correlations and Scales Definition: Taylor's Microscales The Taylor microscales are defined as
where
Definition: Integral Scales, Macroscales The macroscales of turbulence are defined as

,
,
and
are, respectively, the Taylor
longitudinal and lateral microscales. The microscales may be defined by fitting a parabola to the
correlation coefficient curves at 
.
That is,
= Longitudinal Macroscale
= Lateral Macroscale
