Weather
During approach ILS/30L had thunderstorms and rain in the area; but no negative PIREPS or SIGMETS. Noted 10 KT tailwind on final with Tower calling 15 KT quartering headwind. Discussed go-around possibility with First Officer; at 500 FT - with runway insight - Tower called with 'Wind Shear Alert for Runway 30L.' We executed a go-around and were directed to turn 170 degrees and climb to 4;000 FT. During the turn; we saw the aircraft 18 degrees nose up; full go-around power with 0 VSI for approximately 5 seconds at 1;800 FT MSL. The First Officer started the 'Wind Shear Chant' with VSI; Radio Altimeter and Airspeed Callouts. As we passed through this area; we entered an updraft and the aircraft started to climb quickly. Passing 3;500 FT MSL; the First Officer called out 3;000+ VSI and I noted that 'ALT CAP' was illuminated on the FMA and the yoke was pushed all the way forward by the autopilot. As we passed 4;000 FT MSL with about 2;000+ VSI; I disconnected the autopilot and exerted more forward force to stop the climb at approximately 4;400 FT MSL and return to assigned altitude. ATC was notified and said 'no problem; no traffic in your area.' We proceeded to a holding pattern and waited for that rain area to clear before completing a successful approach about 40 minutes later.

A MD-82 Captain executed a go-around at 500 FT after Tower alerted WINDSHEAR ALERT and during the climb experienced a zero VSI with 18 degrees nose up; followed by a 3;000 FT plus FPM climb with nose down.
