Narrative:
Moderate turbulence was reported in the sjn area in the low FL300's (to FL330). I issued climb clrncs 1 min part; and the A300's (first in climb sequence) rate was less than 500 FPM. I was not alerted to this climb rate by either the pilot or 'conflict alert.' if either of these alerts had come to my attention the situation could've easily been avoided. Furthermore; I wouldn't have initiated simultaneous climbs under normal circumstances; but the reports of moderate turbulence demanded expeditious efforts to avoid these altitudes.
Original NASA ASRS Text
Title: ZAB CTLR EXPERIENCED OPERROR AT FL330 WHEN FAILING TO QUICKLY RECOGNIZE SLOW CLB RATE DUE TO TURB.
Narrative: MODERATE TURB WAS RPTED IN THE SJN AREA IN THE LOW FL300'S (TO FL330). I ISSUED CLB CLRNCS 1 MIN PART; AND THE A300'S (FIRST IN CLB SEQUENCE) RATE WAS LESS THAN 500 FPM. I WAS NOT ALERTED TO THIS CLB RATE BY EITHER THE PLT OR 'CONFLICT ALERT.' IF EITHER OF THESE ALERTS HAD COME TO MY ATTN THE SIT COULD'VE EASILY BEEN AVOIDED. FURTHERMORE; I WOULDN'T HAVE INITIATED SIMULTANEOUS CLBS UNDER NORMAL CIRCUMSTANCES; BUT THE RPTS OF MODERATE TURB DEMANDED EXPEDITIOUS EFFORTS TO AVOID THESE ALTS.
