I as Pilot Flying; was initially on a stable approach descending to 3;500 ft. on base for [landing]. I had briefed a Flaps 22 landing. As I was turning base to final (a left turn) and starting further descent; the winds shifted and resulted in a loss of tailwind; and my airspeed increased in the turn. At that same time Tower told us to turn 10 degrees right I believe due to traffic. Through all of this; my approach became unstable with too steep a descent; and got [we] a GPWS sink rate alert. I immediately executed a go around. ATC issued a new clearance and we came back and landed without incident. Suggest some more insight; and different scenarios taught on Flaps 22 landings possibly during training. Because of the higher airspeed vs. Flaps 45; it seems there is an increased chance of unstable approaches; especially if the winds shift as in my case. I carried too much power on this approach and also got distracted with the instruction from Tower to turn opposite of my base to final turn.
EMB-135 First Officer reported executing a go-around after receiving a GPWS 'Sink Rate' alert on a visual approach associated with a wind shift.
