Narrative:

Surface winds were reported on ATIS as calm and runway xx was the assigned runway. While performing pattern work with my student pilot we noted winds from the northwest beginning at approximately 100 ft at 10 KTS and increasing steadily to 30 KTS at pattern altitude. Approach was very difficult for this student as well as the solo student ahead of us in the pattern. I informed the tower of the wind conditions to determine if a runway change could be made to runway yy. The reply was that surface winds were calm. I acknowledged that and again stressed wind direction and velocity with the hope a change would be made. The runway change was made and with each pass; the controller would clear us to land with a sarcastic remark that winds were 330 at 2 KTS; maybe 3. This continued right through the student's solo in the pattern. When I again replied to the controller that the headwind on final after the runway change was greater than 30 KTS; he stated he had no equipment at that altitude. With the advent of taa; ATC could be more receptive to this type of information and be able to recognize the hazard it could present; particularly to larger aircraft attempting to land with these conditions. The taf for the airport called for a nnw wind to begin in the morning hours and; clearly; at least from 100 ft and up; it was already in place. While it did present a learning opportunity for the student; I believe it was unprofessionally handled and potentially a hazard to other aircraft arriving without this information.

Title: C172 in the pattern questioned the runway selection based upon the information being received in-flight; noting that ATC was not receptive to the information he was providing to the Tower.
