rapid pressure raises and decreases
the air gets jammed in the back until it breaks past the incoming pressure and releases.. which creates a small complicated area.. where the incoming air helps force it out until its balanced.

This noise is created by the open windows disrupting the airstream flowing around your car.

its a vacuum effect,the air inside is trying to get out the way its comming in but the amount of air inside cant escape through the rear vents quick enough causing an ear aching chopper noise

Could be disrupted air flow, most likely. But it could also be you seat belt straps flapping in the wind.

Possibly the seat belt sometimes they go crazy from the wind. normally only at higher speeds tho.
