Narrative:

During climb out at 400 ft AGL, received aural and red windshear alert. Accomplished escape maneuver as per aircraft manual. Overtemped both engines for 10-15 seconds. Suspect wake turbulence from aircraft that just departed ahead. All engine parameters and system were normal during remainder of climb. Advised tower of windshear alert. Advised dispatch of situation and continued to dfw. Callback conversation with reporter revealed the following information: reporter indicated that the aircraft taking off immediately ahead was a B737. It was at the liftoff point when reporter received takeoff clearance. There are parallel runways at this airport but they were not being used at the time so with a quartering headwind of approximately 10 KTS they should not have been a factor. No significant WX was in the area and no other reports were made by tower or other aircraft. Crew performed the windshear alert recovery per company policy, even though when reviewing the situation assumed the alert was the result of wake from the B737. Crew elected to continue a short 20 min flight to destination which was also their maintenance base. It was determined that no damage was done to engines.
