Narrative:
On climbout encountered moderate turbulence at 3;000 MSL. At approximately 4;000 MSL severe turbulence and windshear. Escape maneuver proceeded with airspeed swing from approximately 200 KTS to 290 KTS then back to approximately 210 KTS. Max pitch up approximately 20 degrees; max bank approximately 30 degrees. Engines not over boosted. Speeds and pitch estimates due to inability to read flight instruments due to turbulence. Incident reported to ATC; dispatch and maintenance. First officer is to be commended for calling out airspeeds and assisting in situational input throughout event. Incidentally; the only other bona fide wind shear event that I have ever encountered in 38 years of flying was also with this first officer. While we train for windshear in the simulator the only component missing would be abrupt lateral bank changes and loss of visual acuity due to severe turbulence.
