Narrative:

Rides in sector were moderate turbulence climbing through FL330 with a line of thunderstorms moving west to east. I was attempting to accommodate numerous aircraft to stay below the turbulence. I had 2 aircraft about 12 NM apart heading swbound at FL280 -- #1 40 KTS faster than #2. I assigned aircraft #1 and aircraft #2 FL310 to avoid another aircraft at FL280. All were slowly converging and speed differentials was not going to achieve 5 NM separation. I assigned aircraft #2 a 320 degree heading; 40 degree turn to go behind aircraft #1. I assigned aircraft #1 a climb to FL330. The 40 degree turn seemed not to be working; so when aircraft were about 10 mi apart; issued aircraft #2 a 270 degree heading; 50 degree left turn. Aircraft #2 turned to the left; but not in time to avoid loss of separation. Ended up with 3-5 mi and 1600 ft.

Title: ZNY CTLR EXPERIENCED OPERROR NEAR FL310 WHILE PROVIDING VECTORS AND ALTERNATE ALTS TO AVOID TURB.

Narrative: RIDES IN SECTOR WERE MODERATE TURB CLBING THROUGH FL330 WITH A LINE OF TSTMS MOVING W TO E. I WAS ATTEMPTING TO ACCOMMODATE NUMEROUS ACFT TO STAY BELOW THE TURB. I HAD 2 ACFT ABOUT 12 NM APART HDG SWBOUND AT FL280 -- #1 40 KTS FASTER THAN #2. I ASSIGNED ACFT #1 AND ACFT #2 FL310 TO AVOID ANOTHER ACFT AT FL280. ALL WERE SLOWLY CONVERGING AND SPD DIFFERENTIALS WAS NOT GOING TO ACHIEVE 5 NM SEPARATION. I ASSIGNED ACFT #2 A 320 DEG HDG; 40 DEG TURN TO GO BEHIND ACFT #1. I ASSIGNED ACFT #1 A CLB TO FL330. THE 40 DEG TURN SEEMED NOT TO BE WORKING; SO WHEN ACFT WERE ABOUT 10 MI APART; ISSUED ACFT #2 A 270 DEG HDG; 50 DEG L TURN. ACFT #2 TURNED TO THE L; BUT NOT IN TIME TO AVOID LOSS OF SEPARATION. ENDED UP WITH 3-5 MI AND 1600 FT.
