Environment - Non Weather Related; Procedure
Descending on the BOOVE3 RNAV arrival into DFW from GUTZZ intersection; we were following a B737-800 on same arrival that was approximately 10 miles ahead. With a 35-40 knot tailwind from the southwest; we began to experience uncommanded rolls; some rather abrupt as the arrival altitudes narrowed. I disconnected the autopilot & continued the arrival parallel & just east of the RNAV course to stay outside the lead aircraft's wake. We notified Ft Worth ATC of the event & our intention to stay just east of course to maintain slightly upwind of the B737's wake.Winds aloft basically aligned with the northeast direction of this arrival; also with the precision of today's RNAV SIDs & STARs; these events are no longer random; but are occurring with any RNAV arrival that lines up with the winds aloft. Events range from a momentary 'thump' over a turn at an intersection; to longer duration events such as above. Also; the B737-800 and -900 series aircraft are slightly heavier than the MD80s & a different wing design; which I believe is a contributing factor.
MD-80 First Officer reported encountering wake turbulence in trail of a B737-800 on arrival into DFW.
