korteweg deVries equation and solitons

The Korteweg -deVries equation accounts for the existence of solitons
in water. Al Osborne has done some interesting work on solitons in
water layers such as the giant solitons off the coast of sumatra
mentioned in the link below

But do solitons exist on a smaller scale in the boundary layers of air
that flow over an aircraft wing?
