In order to establish the relationship of the distance of looping and trapping plumes' first touching ground with wind speed and to predict the closest ground level approach of fluctuating plumes, a visual record of plume dispersion at Mt. Isa, Australia, where terrain is flat, was provided by using a movie camera.
As results of the treatment of the record in connection with meteorological data associated, following conclusions were drawn;
1) Linear relationship between both factors when plume is looping or trapping was established.
2) The minimum distance of plume's first touching ground appears to be around stack height and to happen when plume is trapping.
