Sorry, Google won't let me post this as a follow-up.

In the broadest sense, the reynolds number is a measure of the degree
of
turbulence. A low reynolds number corresponds to laminar flow while
a
high reynolds number corresponds to turbulent flow. However, as
turbulence
is fundamentally a chaotic phenomenon, it is possible to maintain
laminar
flow at a higher reynolds number until a perturbation initiates the
turbulence.

The reynolds number is important for determining boundary layer
separation,
drag and convective heat transfer coefficients.

If Reynolds is a woman, I'd like to have her number too..

Thank you Fred, this is the brief yet comprehensive description I was
after. It explains why there are various RN values at various positions
along the wing chord - which was much of my initial bewilderment.
