Narrative:

We received a wind shear alert on our departure climb. Previously at the gate we had briefed the low level wind shear considerations which was posted in the ATIS. [The first officer] was flying the leg departing 27R and at approximately 1000 ft AGL we received the wind shear warning. I assisted [the first officer] in the wind shear maneuver calling for max thrust and no configuration changes to the aircraft. The warning lasted through 1500 ft AGL at which point it went away; due to wind shear detection stopping at this altitude. We maintained no configuration changes for another several hundred feet until we verified a positive airspeed trend vector in addition to the climbing altitude. At this point we cleaned up the aircraft and [performed] after takeoff checks.at takeoff we had been issued a left turn to heading 230; which we initially began at 400 ft AGL; however stopped turn at approximately 250 degrees when the wind shear 'GA/ws' mode became active and gave us a heading sync. After we were clear of the wind shear we resumed the turn to 230 degrees and leveled at our top of climb 5000 feet; and I informed ATC of the wind shear event. During the event I didn't notice a decreasing performance in airspeed; yet there didn't seem to be an increasing trend vector either; which I believe this stagnation may have triggered the alert.
