Windshear your not very likely to get anything out of us.
I'd like something like "going around, wind shear". That way as the Air Traffic Controller I am able to provide a service to other aircraft, the a/c at the holding point, following a/c on final, a/c on the adjacent rwy, a/c on different freq.
I know you are busy but a couple of key words provides sufficient info. Followup later on about the height, severity, type of w/s.
