Is this to say that in this wave system the air motion, at least at
certain altitude levels, has vertical velocity components that oscillate
between positive and negative values with increasing downwind distance?
-- maybe with something like a highly damped sinusoidal variation if
plotted vs downwind distance?
Even with my feeble to nonexistent knowledge of fluid mechanics and
aerodynamics I can picture that.
If so, what's the approximate horizontal period of the oscillation?
Would it happen also with a thin vertical wall?
