Good point. The analogy was to what is called "suction cavitation" which can
happen with vacuum pumps. However, there must still be a liquid vapor
present for that to happen.
But this is in dry desert, correct ? There isn't enough water vapor for
"suction cavitation" unless the turbulence of the b

The sound level is certainly intense from helicopter blades... not

Yellow is a characteristic color of salinity and many sandy deserts are
highly saline.
Instead of sand, per se, the emission could be caused by cavitation in
saline air.
