The passengers will seldom notice anything of this turbulence. The turbulence is a small scale one and can cause damage. The manoeuvring of the aircraft will be made more difficult or even impossible. For the passengers the flight will be unpleasant. The turbulence is a large scale one (waving) so that the aircraft will be difficult to manoeuvre. The passengers will feel some discomfort.
