Inflight Event / Encounter Weather / Turbulence; Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Procedure; Environment - Non Weather Related
On initial climb out at approximately 1;000 ft. AGL; we got a wind shear warning from the aircraft. We performed the escape maneuver and climbed out of the condition. We believe it must have been CAT (Clear Air Turbulence) or wake turbulence from another aircraft that triggered the warning. Just prior to receiving it we encountered what appeared to be wake turbulence.
CRJ900 Captain reported a wind shear warning on departure.
