Narrative:
At 10000 ft restr to 250 KIAS. Received clearance to climb to 12000 ft MSL at 250 KIAS. As climb began got an ATC clearance to 'climb immediately to 12000 ft and turn left to 360 degrees turn left now.' we began the climb and the turn and got an RA to 'monitor vertical speed,' followed by a 'descend with 300 FPM rate indicated,' followed by a 'monitor vertical speed.' as we had begun our climb and turn per ATC, we didn't have time to react to the TCASII descent but broke our rate as the target was a steady 300 ft above us for 3-5 seconds. Due to the assigned airspeed of 250 KIAS and a clear maneuver of 237 KIAS, we didn't have much room for maneuvering. Target passed 1 1/2 mi aft at 300 ft above as we were passing 11000 ft MSL. Target first appeared at 1 O'clock position, -1000 ft, passed 2-3 O'clock position, then aft to the left at +300 ft. Per ATC the target was +300 ft passing aft at 1 1/2 mi.

Title: MD80 CREW HAD TCASII RA IN ZNY CLASS E.
Narrative: AT 10000 FT RESTR TO 250 KIAS. RECEIVED CLRNC TO CLB TO 12000 FT MSL AT 250 KIAS. AS CLB BEGAN GOT AN ATC CLRNC TO 'CLB IMMEDIATELY TO 12000 FT AND TURN L TO 360 DEGS TURN L NOW.' WE BEGAN THE CLB AND THE TURN AND GOT AN RA TO 'MONITOR VERT SPD,' FOLLOWED BY A 'DSND WITH 300 FPM RATE INDICATED,' FOLLOWED BY A 'MONITOR VERT SPD.' AS WE HAD BEGUN OUR CLB AND TURN PER ATC, WE DIDN'T HAVE TIME TO REACT TO THE TCASII DSCNT BUT BROKE OUR RATE AS THE TARGET WAS A STEADY 300 FT ABOVE US FOR 3-5 SECONDS. DUE TO THE ASSIGNED AIRSPD OF 250 KIAS AND A CLR MANEUVER OF 237 KIAS, WE DIDN'T HAVE MUCH ROOM FOR MANEUVERING. TARGET PASSED 1 1/2 MI AFT AT 300 FT ABOVE AS WE WERE PASSING 11000 FT MSL. TARGET FIRST APPEARED AT 1 O'CLOCK POS, -1000 FT, PASSED 2-3 O'CLOCK POS, THEN AFT TO THE L AT +300 FT. PER ATC THE TARGET WAS +300 FT PASSING AFT AT 1 1/2 MI.
