Narrative:

While working the flight data position and assisting the radar controller with coordination; the tower called down and said that aircraft X was needing to go missed approach due to microburst activity on the pns airport. The aircraft X went missed without incident; as well as the 2 commuter jets that were on vectors to the ILS runway 17 at pns. The action by the tower controller confused us in the TRACON P31; since we were not aware they had the capability of issuing microburst reports; and the closest WX was about 25 mi to the west. The equipment in the TRACON is only a single ribbon display that depicts the center field winds of a 5 sensor LLWAS. It was indicating winds of 140 degrees at 15 KTS gusting to 29 KTS at the time of the action by the tower. We knew that there were LLWS advisories; and they were issued to the pilots; but had we had the capability of knowing about the microburst on the airfield; quicker action by the radar controller could prevent any aircraft in the future from being vectored into known microbursts.

Title: P31 CTLR DESCRIBED MULTIPLE GAR EVENTS DUE TO WINDSHEAR; CLAIMING WINDSHEAR EQUIP AVAILABILITY IN THE TRACON MAY HAVE PREVENTED GAR'S.

Narrative: WHILE WORKING THE FLT DATA POS AND ASSISTING THE RADAR CTLR WITH COORD; THE TWR CALLED DOWN AND SAID THAT ACFT X WAS NEEDING TO GO MISSED APCH DUE TO MICROBURST ACTIVITY ON THE PNS ARPT. THE ACFT X WENT MISSED WITHOUT INCIDENT; AS WELL AS THE 2 COMMUTER JETS THAT WERE ON VECTORS TO THE ILS RWY 17 AT PNS. THE ACTION BY THE TWR CTLR CONFUSED US IN THE TRACON P31; SINCE WE WERE NOT AWARE THEY HAD THE CAPABILITY OF ISSUING MICROBURST RPTS; AND THE CLOSEST WX WAS ABOUT 25 MI TO THE W. THE EQUIP IN THE TRACON IS ONLY A SINGLE RIBBON DISPLAY THAT DEPICTS THE CTR FIELD WINDS OF A 5 SENSOR LLWAS. IT WAS INDICATING WINDS OF 140 DEGS AT 15 KTS GUSTING TO 29 KTS AT THE TIME OF THE ACTION BY THE TWR. WE KNEW THAT THERE WERE LLWS ADVISORIES; AND THEY WERE ISSUED TO THE PLTS; BUT HAD WE HAD THE CAPABILITY OF KNOWING ABOUT THE MICROBURST ON THE AIRFIELD; QUICKER ACTION BY THE RADAR CTLR COULD PREVENT ANY ACFT IN THE FUTURE FROM BEING VECTORED INTO KNOWN MICROBURSTS.
