IIRC there were a number of incidents of A319/320/321 aircraft entering severe roll oscillation in full config in strong cross wind situations, perhaps late 90's very early 2000's? At least one damaged the wing. They were investigated by more than one XAA and Airbus ordered to roll out compulsory software updates as a fix. Something to do with yaw dampening feedback loop and corresponding spoiler interaction (only in a specific config/set of conditions?) but could be way off on the detail as it was a long time ago... perhaps someone more resourceful than I could find the reports/advisories if of interest.
Whilst rotor/wave and other obstacle-induced turbulent air may have caused an initial upset that led to a go-around, the oscillation seen in the videos is something else entirely, IMV. Happy to be corrected.
The OP had the correct verbiage in either case though: disturbing!
