Narrative:
During descent into mia on the heatt arrival, encountered moderate to heavy turbulence descending through 13000 ft. Turbulence was encountered at 310 KTS, lasted about 15 seconds and had right rolling moment. Traffic before and after did not experience the turbulence. We suspected it to be wake turbulence produced by the B747 12 mi ahead of us on the same arrival.
