Narrative:

We executed a go around while on a visual approach to runway 18C at clt after encountering a wake turbulence event at approx. 150 - 200 AGL just before landing. It was obvious to the crew that we had a wake turbulence encounter with the A321. While on a visual approach to 18C at clt we were in trail of an airbus A321 approx. 4 miles in front of us; the separation was normal for clt. It was noted that the winds at around 300 feet were from the northwest at 15 to 20 KTS. All aspects of the approach were normal and stable until approximately 200 feet AGL when the aircraft started an abrupt un-commanded roll to the left. The autopilot was off and I was hand flying. I reacted to the un-commanded roll; rolling wings level and executing a go around due to the interruption of a stabilized approach and the close proximity to the ground. ATC was notified; we were subsequently vectored around for a second visual approach that concluded with a normal approach and landing. All information provided to the crew which included; ATC instruction; TCAS information; as well as visual separation indicated sufficient separation existed between the two aircraft to avoid any wake turbulence conflict. I believe the weather conditions played a major role in the A321's wake vortices remaining in the approach area for an extended amount of time caused by the wind direction aloft. I have no suggestions in how to avoid this event from occurring again because the separation provided by ATC and wind conditions for the landing runway are all normal procedures for many ATC facilities.
