EMB ERJ 145 ER/LR
Flight Crew Air Transport Pilot (ATP)
Inflight Event / Encounter Unstabilized Approach; Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Executed Go Around / Missed Approach; Flight Crew Took Evasive Action
Procedure; Environment - Non Weather Related
Upon reaching 200 we encountered wake turbulence from the preceding B737 that started to roll the aircraft. The FO quickly called for a go-around because the approach became unstable. Airframe buffeting and aircraft roll was detected. ATC spacing was too close for the wake to dissipate.
EMB-145 Captain reported executing a go-around at 200 AGL after encountering wake turbulence in trail of a B737 landing at STL.
