Turbulence and airspeed

The only part of turbulence I truly DON'T understand is the kind that
tips
one wing up violently. How the heck a "parcel" of air can be so
different
in the span of just 30 feet (our approximate wingspan) escapes me, but
I've
had turbulence push one wing up so hard that it took nearly full
opposite
aileron to remain level.


When a parcel of air is swirling around, the other parcel of air has to
go somewhere to get out of its way. Turbulence is the air (or water,
or any fluid) burbling around all over the place, up, down, left right,
clockwise, counterclockwise, and there are boundaries all over the
place. You crossed several boundaries in succession.
