I would not add 'go around ' call to any windshear or terrain warning ,as any atempt to do a normal go-around will compromise safety.
Few important differences between gpws warnings and 'go-around':
*disconnect a/p and a/t
*AGRESSIVELY apply maximum thrust
* initiall pitch 20 for 'terrain' (or 15 for widshear)
*go to PLI or stick shaker if needed.
*retract speedbrakes
*DO NOT CHANGE configuration.
Any attempt fo do a normal go-around will not respect the above requirements, and may drastically compromise safety.
I would take the FDR data for the specific flight ,and discussed it with both pilots involved, and even with the rest of the pilots, so to make clear what the trajectory was,the ground clearance , and what would be the difference between go-around and terreain avoidance manouvre.
