Weather
On approach to Reno [Runway] 16R; encountered moderate turbulence; LLWS; shifting high winds with severe gusts and blowing dust.  Airspeed fluctuations on final with a shift to a tailwind necessitated a missed approach go around. While accomplishing the missed approach encountered strong moderate turbulence at flaps 3 and the gear up; atmospheric conditions created an airspeed gain in excess of 30 to 45 knots thus overspeeding the flaps for configuration. The pitch was immediately adjusted but the overspeed occurred with a massive airspeed gain. In reconfiguring to flaps one; a similar airspeed gain caused a second overspeed in the flaps one configuration. The pitch attitude was adjusted and no further over speeds occurred. Upon taxi to gate; overspeed condition was written up and reported to maintenance for inspection.
The winds were changing constantly gusting to 35/50 knots. The First Officer configured early to get the plane stabilized. At approx. 1;000 feet we were losing airspeed and altitude and showing a 15 knot tailwind while tower was still calling a 30 knot headwind. I could also see a dust line coming down the runway towards the landing zone. I directed a go around and while climbing we got the 30-40 knot headwind gusts. While getting the flaps from 3 to 1; the airspeed hit the bottom of the red line twice. The moderate turbulence and gusts made it difficult to read the speed tape and fly the plane. After landing on the second attempt; I called Maintenance Control and wrote up the flap overspeed.
A320 flight crew experiences turbulence and strong gusty winds during approach to Runway 16R; resulting in a decision to go-around. During the go-around; flap overspeed occurs; and again while configuring for the subsequent approach.
