Training in progress on Local control. First time instructor is observing trainee. Trainee had Aircraft Y in the pattern to Runway 22 and Aircraft Z on 5 mile final to Runway 32. Trainee asked the Aircraft Y in the pattern if he could make a short approach; to which he said yes. So the trainee had Aircraft Y make a short approach with Aircraft Z on 4.5 mile final. Then Aircraft X called up for departure at the approach end of Runway 32. The trainee cleared Aircraft X for an immediate departure; but Aircraft Y was already on the base turn to Runway 22. Aircraft X was airborne at about Taxiway B when the trainer sent Aircraft Y around on Runway 22. There was no loss of separation; the weather was clear but the timing could have been a lot better and Aircraft Y passed behind the departing Aircraft X. As Controller-in-Charge I noticed that the situation wasn't going to work and said so to the instructor. I also told the trainee that by having Aircraft Y make a short approach they created the situation with departing Aircraft X. A normal approach on Aircraft Y with Aircraft Z on final would have allowed plenty of room for Aircraft X to depart Runway 32.I told the instructor that I would have appreciated if they would have not let the situation continue even after I said I felt it wasn't going to work. I told the trainee the situation was created when having Aircraft Y make a short approach when it wasn't needed. I also told the trainer that I wanted traffic issued; but that wasn't done either.
Controller on the Job training was occurring at the Local Control position. The trainee Controller cleared an aircraft for takeoff with another aircraft on short final to an intersecting runway. The instructor took over and sent the arrival around preventing a loss of separation. The reporter was Controller-in-Charge at the time and felt the instructor should have resolved the situation in a timelier manner.
