Especially as an error in the anemometric information (... AF447) will affect the Stall Warning.

The value of the AoA SW depends on the Mach number. At high Mach number, the AoA SW is set at a value such that the warning occurs just before encountering the pitch up effect and the buffeting.
If the anemometric information used to set the AoA SW is erroneous, the SW will not sound at the proper AoA.
