Human Factors; Procedure
I was working arriving aircraft to Runway 8L. A B737 was on a 3 mile left base for Runway 8L on a visual approach. The B737 initiated a go-around due to windshear. I climbed aircraft to 3;000 FT and turned to a heading of 360 (normal procedure). I issued an additional turn to a heading of 300 for a downwind back to the airport and was getting ready to transfer communication when I notice a B767 going around on Runway 8R and turning to the north inside the B737. I immediately turned the B737 back to a heading of 360 to avoid conflict with the B767. Then the Monitor took over and climbed the B737 to 4;000 FT and initiated another turn. The Monitor then assumed control of the B767 to bring the aircraft around for another approach. I had no idea I90 was turning the aircraft on Runway 8R to the north. Some communication would have been helpful for this event.
I was going back and forth between TMU and Monitor. I was working Monitor north for about 15 minutes during a period of heavy thunderstorm activity. I was made aware that an aircraft was going around on [Runway] 8L because of weather. I asked Local North to give me control so that I could turn him back toward the final; approved; I then noticed a heavy B767 going around on [Ruwnay] 8R. The heavy was turning northerly but I was unaware who was working him so I delayed giving any control instructions until I could ascertain the correct actions. Local North; for reasons unbeknownst to me; turned the B737 into the flight path of the 767. While it is outside of my area of jurisdiction; I took action to prevent a possible collision. The B737 did have the B767 in sight and was instructed to maintain visual separation. I do not know if separation was compromised and I do not recall the collision alert sounding. Aircraft that go missed approach inside the final approach fix should be separated by the Tower and then delivered to the appropriate sector when they are separated.
IAH Controller described a go-around event resulting in a conflict when coordination between the Tower and TRACON was ineffective.
