What about when parked on the ramp...

So the air molecules are not 'trying to equalise their speed over the wing' they are sitting still while the wing is doing the moving past them and pushing them up or down.
Most wind tunnels, of course, move the air molecules while keeping the wing static, and I wonder if this is where the confusion arose?
In a 50 kt wind on a remote strip in Alaska? Do the air molecules do different things there than in a wind tunnel?
