Rides reported good and subsequently given climb to FL310. Climbing out of FL305 encountered severe mountain wave turbulence causing immediate airspeed increase above limits and uncontrollable climb. Disconnected autopilot and attempted immediate correction. Topped out at FL330; then corrected back to FL310.
