Narrative:
Aircraft #1 was sbound climbing to FL330. Aircraft #2 was northbound level at FL310. I initially turned aircraft #1 southeast on course, but didn't realize aircraft #2 was there (heavy traffic with data block overlap played a part in this). I realized aircraft #2 was a factor before conflict alert activated and attempted to turn both and descend aircraft #2. I had to wait a short time to descend aircraft #2 because of traffic at FL290. Also, I didn't realize that the upper winds were as strong as they were, which resulted in aircraft #1 picking up speed and the turns not being as effective as I had hoped. Aircraft #2 arrived on my frequency prior to my accepting the radar handoff which, I believe, compromised my normal scan for that aircraft. I also believe that had I fully appreciated the direction and speed of the winds, I would have used more degrees of turn to save lateral separation.
Original NASA ASRS Text
Title: ZID CTLR EXPERIENCED LOSS OF SEPARATION WITH AN ENRTE AND CLBING ACFT AT FL300.
Narrative: ACFT #1 WAS SBOUND CLBING TO FL330. ACFT #2 WAS NBOUND LEVEL AT FL310. I INITIALLY TURNED ACFT #1 SE ON COURSE, BUT DIDN'T REALIZE ACFT #2 WAS THERE (HVY TFC WITH DATA BLOCK OVERLAP PLAYED A PART IN THIS). I REALIZED ACFT #2 WAS A FACTOR BEFORE CONFLICT ALERT ACTIVATED AND ATTEMPTED TO TURN BOTH AND DSND ACFT #2. I HAD TO WAIT A SHORT TIME TO DSND ACFT #2 BECAUSE OF TFC AT FL290. ALSO, I DIDN'T REALIZE THAT THE UPPER WINDS WERE AS STRONG AS THEY WERE, WHICH RESULTED IN ACFT #1 PICKING UP SPD AND THE TURNS NOT BEING AS EFFECTIVE AS I HAD HOPED. ACFT #2 ARRIVED ON MY FREQ PRIOR TO MY ACCEPTING THE RADAR HDOF WHICH, I BELIEVE, COMPROMISED MY NORMAL SCAN FOR THAT ACFT. I ALSO BELIEVE THAT HAD I FULLY APPRECIATED THE DIRECTION AND SPD OF THE WINDS, I WOULD HAVE USED MORE DEGREES OF TURN TO SAVE LATERAL SEPARATION.
