Narrative:

First officer flew the ILS 1 DOT high on the G/south for wake turbulence avoidance. Forward visibility was reduced rapidly as we descended through 400' AGL due to thick haze/morning fog. Suddenly we encountered roll action and airspeed loss. The first officer initiated a go around. As we both were very busy trying to get the aircraft flying safely and climbing, the controller started yelling at us: 'what are you doing light transport X? What is the problem? Do you need assistance?' all those radio calls from the tower were very untimely and unsafe. We were 100-200' AGL, working hard and using the intercom for crew coordination and giving each other instructions when the tower was yelling at us. Very unsafe!! I called tower at 400' AGL with go around notice--plenty in time for them to coordinate traffic. We flew a traffic pattern and landed safely.

Original NASA ASRS Text

Title: LTT X LOSS OF ACFT CTL DUE TO WAKE TURBULENCE.

Narrative: F/O FLEW THE ILS 1 DOT HIGH ON THE G/S FOR WAKE TURB AVOIDANCE. FORWARD VISIBILITY WAS REDUCED RAPIDLY AS WE DSNDED THROUGH 400' AGL DUE TO THICK HAZE/MORNING FOG. SUDDENLY WE ENCOUNTERED ROLL ACTION AND AIRSPD LOSS. THE F/O INITIATED A GAR. AS WE BOTH WERE VERY BUSY TRYING TO GET THE ACFT FLYING SAFELY AND CLBING, THE CTLR STARTED YELLING AT US: 'WHAT ARE YOU DOING LTT X? WHAT IS THE PROB? DO YOU NEED ASSISTANCE?' ALL THOSE RADIO CALLS FROM THE TWR WERE VERY UNTIMELY AND UNSAFE. WE WERE 100-200' AGL, WORKING HARD AND USING THE INTERCOM FOR CREW COORD AND GIVING EACH OTHER INSTRUCTIONS WHEN THE TWR WAS YELLING AT US. VERY UNSAFE!! I CALLED TWR AT 400' AGL WITH GAR NOTICE--PLENTY IN TIME FOR THEM TO COORDINATE TFC. WE FLEW A TFC PATTERN AND LANDED SAFELY.
