Situational Awareness
Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Environment - Non Weather Related; Procedure
During landing; the First Officer flying at about 120 feet; we encountered wake turbulence of the previous landed B737 who had gotten off the runway and was on the taxiway when we were 1/4 mile from the runway. The aircraft rolled to the left and caused the GPWS to give a bank angle warning. The First Officer reacted quickly and rolled the aircraft back to wings level as the aircraft was passing 100 feet. [We were] at Vref +5 and in a normal position to continue the landing. The First Officer decreased the power toward Vref and completed a normal landing. I taxied to the gate and during the walk around the First Officer didn't find anything amiss with the aircraft. The wake turbulence of the previous B737 lingering on the runway longer than normal. We could have had more separation from the previous aircraft on the approach.
CRJ-200 Captain reported encountering wake turbulence just before touchdown at IAD from the B737 they were following to the runway.
