Narrative:

This event occurred approximately 20 mi northwest of runway 12 at mia. We were at 3000 ft MSL and approximately 200 KIAS. We were given a dogleg vector to final for runway 12. Due to a strong tailwind and severe WX on final approach, captain elected to break off the approach. We were given a right turn to a northerly heading and cleared to climb to 6000 ft. After completing the turn and while climbing at approximately 1000 FPM, we noticed traffic at 11 O'clock high. We immediately cut the climb rate and simultaneously got a 'descend' RA on TCASII. This occurred at approximately 5600 ft. We followed the descend RA and while in the descent, at approximately 5300 ft, ATC advised us to 'descend and maintain 5000.' we leveled off at 5000 ft and the traffic passed overhead well clear. There were numerous stray thunderstorms in the area at the time and a heavy load of jet and turboprop traffic. The controller was very busy. A constant problem with severe WX in terminal areas is that the controllers do not see the same level of thunderstorm activity the pilots do. A dangerous result if the situation is that pilots do not and cannot always follow controllers' instructions or the approach clrncs.

Original NASA ASRS Text

Title: LGT MAKES MISSED APCH AND HAS TCASII RA.

Narrative: THIS EVENT OCCURRED APPROX 20 MI NW OF RWY 12 AT MIA. WE WERE AT 3000 FT MSL AND APPROX 200 KIAS. WE WERE GIVEN A DOGLEG VECTOR TO FINAL FOR RWY 12. DUE TO A STRONG TAILWIND AND SEVERE WX ON FINAL APCH, CAPT ELECTED TO BREAK OFF THE APCH. WE WERE GIVEN A R TURN TO A NORTHERLY HDG AND CLRED TO CLB TO 6000 FT. AFTER COMPLETING THE TURN AND WHILE CLBING AT APPROX 1000 FPM, WE NOTICED TFC AT 11 O'CLOCK HIGH. WE IMMEDIATELY CUT THE CLB RATE AND SIMULTANEOUSLY GOT A 'DSND' RA ON TCASII. THIS OCCURRED AT APPROX 5600 FT. WE FOLLOWED THE DSND RA AND WHILE IN THE DSCNT, AT APPROX 5300 FT, ATC ADVISED US TO 'DSND AND MAINTAIN 5000.' WE LEVELED OFF AT 5000 FT AND THE TFC PASSED OVERHEAD WELL CLR. THERE WERE NUMEROUS STRAY TSTMS IN THE AREA AT THE TIME AND A HVY LOAD OF JET AND TURBOPROP TFC. THE CTLR WAS VERY BUSY. A CONSTANT PROB WITH SEVERE WX IN TERMINAL AREAS IS THAT THE CTLRS DO NOT SEE THE SAME LEVEL OF TSTM ACTIVITY THE PLTS DO. A DANGEROUS RESULT IF THE SIT IS THAT PLTS DO NOT AND CANNOT ALWAYS FOLLOW CTLRS' INSTRUCTIONS OR THE APCH CLRNCS.
