Narrative:

I requested wind report from aircraft #1. Aircraft #1 stated wind 230 degrees at 45 KTS. I vectored aircraft #2 30 degrees left to heading 231 degrees. Aircraft #2 ground speed increased speed from 410 KTS to 460 KTS. I vectored aircraft #2 turn left heading 205 degrees. Aircraft #2 issued descent FL370. Aircraft #1 vectored 40 degrees left. Separation lost. The actual wind verified by 2 other aircraft 330 degrees at 45 KTS.

Title: ZKC ARTCC CTLR HAS A LOSS OF SEPARATION WITH AN OVERTAKE SIT.

Narrative: I REQUESTED WIND RPT FROM ACFT #1. ACFT #1 STATED WIND 230 DEGS AT 45 KTS. I VECTORED ACFT #2 30 DEGS L TO HDG 231 DEGS. ACFT #2 GND SPD INCREASED SPD FROM 410 KTS TO 460 KTS. I VECTORED ACFT #2 TURN L HDG 205 DEGS. ACFT #2 ISSUED DSCNT FL370. ACFT #1 VECTORED 40 DEGS L. SEPARATION LOST. THE ACTUAL WIND VERIFIED BY 2 OTHER ACFT 330 DEGS AT 45 KTS.
