Vertical winds?? Banked turns?? I suggest they would have no practical bearing on the AOA. If the aeroplane is balanced in a turn, I'd reckon the airflow around both sides of the nose would be, for all intents and purposes, exactly the same. As for "vertical winds", that's all AOA is; anybody who's flown these types of aeroplanes would notice the stick shaker zipper bouncing up and down in turbulence when you're slow, but to say they are "useless without algorithms" is going a bit overboard.
Read Boeings Aero-12. That is where this information comes from.
It has been here several times, but keep getting deleted, so you will have to look up the issues with AoA measurement, calibration, latency, and other issues on your own.
