Narrative:

We were on a flight from oakland to reno, nev. We were advised of light to moderate turbulence on approach to reno before our departure. On our descent we prepared for a bumpy ride and advised the flight attendants to secure the cabin early. Cloud cover was about 11000 scattered and it was at this point we encountered moderate turbulence momentarily with light occasional moderate turbulence. We were cleared for the visual approach and noticed a large area of dust blowing 1 mi north or runway 16R on our approach. We continued and at 7000 ft we encountered a 40 KT increase in speed and about 5 seconds later a windshear alert. I applied go around power and attitude when we encountered moderate to severe turbulence. The turbulence continued to 10500 ft where it continued light to moderate to 18000 ft, we diverted to las vegas. It was the first time I was in that kind of turbulence and not in a thunderstorm. The factors leading to the go around: increase in airspeed, windshear alert were textbook to simulator training.

Title: ACR ENCOUNTERS SEVERE TURB AND WINDSHEAR ON APCH TO LAND.

Narrative: WE WERE ON A FLT FROM OAKLAND TO RENO, NEV. WE WERE ADVISED OF LIGHT TO MODERATE TURB ON APCH TO RENO BEFORE OUR DEP. ON OUR DSCNT WE PREPARED FOR A BUMPY RIDE AND ADVISED THE FLT ATTENDANTS TO SECURE THE CABIN EARLY. CLOUD COVER WAS ABOUT 11000 SCATTERED AND IT WAS AT THIS POINT WE ENCOUNTERED MODERATE TURB MOMENTARILY WITH LIGHT OCCASIONAL MODERATE TURB. WE WERE CLRED FOR THE VISUAL APCH AND NOTICED A LARGE AREA OF DUST BLOWING 1 MI N OR RWY 16R ON OUR APCH. WE CONTINUED AND AT 7000 FT WE ENCOUNTERED A 40 KT INCREASE IN SPD AND ABOUT 5 SECONDS LATER A WINDSHEAR ALERT. I APPLIED GAR PWR AND ATTITUDE WHEN WE ENCOUNTERED MODERATE TO SEVERE TURB. THE TURB CONTINUED TO 10500 FT WHERE IT CONTINUED LIGHT TO MODERATE TO 18000 FT, WE DIVERTED TO LAS VEGAS. IT WAS THE FIRST TIME I WAS IN THAT KIND OF TURB AND NOT IN A TSTM. THE FACTORS LEADING TO THE GAR: INCREASE IN AIRSPD, WINDSHEAR ALERT WERE TEXTBOOK TO SIMULATOR TRAINING.
