Narrative:

The first officer was flying the aircraft and we had just taken off from hou's runway 12R. We were passing 1500 ft AGL/MSL approximately 15- 16 degrees nose up, in a left turn to an assigned heading of 360 degrees on the hobby 8 SID. The SID specifies that the turn be completed within 3 DME, and we were in a 25-30 degree left bank. At that altitude, the TCASII issued a command to descend at a rate of approximately 2000 FPM. The first officer began a pushover to comply while continuing the turn. The 'red square/intruder' was directly on the nose indicating 100 ft above our altitude. As the nose of the aircraft was passing through the horizon, the TCASII issued the 'clear of conflict' advisory. As we began to resume the climb the tower advised us to switch to departure. We informed him that had just complied with a TCASII RA. He said nothing, and we switched to departure. The visibility was reported as 6 mi with haze, temperature 83 degrees, wind 150/5. The other aircraft was never seen, type is unknown.
