Narrative:
Climbing out of atl on the geetk 5 departure; behind an md-90; encountered wake turbulence over klegg waypoint. Took off from 8R at 42000 pounds; I was the pilot flying with the flight director and no autopilot. Wind was 3004/19 KTS at klegg. We encountered a very sudden roll of about 10 degrees left then ten to the right for a total change of 20 degrees. The roll was very sudden and forceful. Both aircraft were climbing on a very accurate RNAV departure. The wake must not have dissipated adequately prior to our arrival at the point in space and altitude. I kept the wings level and kept climbing to the assigned altitude of 14000. The captain made PA to keep the passengers informed.
