The actual effect that building downwash will have on an emissions plume will depend on many factors, primarily the exit velocity and temperature of the emissions and the current weather conditions.  All of these factors go into AERMOD's PRIME algorithm.  BREEZE Downwash Analyst's PRIME Plume Rise View takes all of these calculations, normally hidden from the AERMOD user, and puts them into the simplest form possible-a 3D image showing the size and shape of the plume during each hour that AERMOD was run for.
