Narrative:
In cruise at FL370; [we] began to encounter moderate turbulence. Then encountered an area of severe turbulence and wind shear. Airspeed rapidly increased (not reaching zipper) then rapidly decreased approximately 15 knots into the hook. Full power was applied as the aircraft began to buffet. Aircraft entered an uncommanded descent as well. Autopilot was disconnected and full power applied. Nose down pitch was initiated in order to recover from the buffet condition. Aircraft was recovered normally with an altitude loss of approximately 500 feet.
