| Abstract |
Plume rise calculations are based on the equations of Briggs (1975) for use with variable vertical profiles of temperature and wind speed. Results are presented for small and large chimneys, based on five years of twice-daily rawinsondes throughout the contiguous United States. In addition to effective chimney heights, data are also generated on the frequencies of plume center-lines below, within, or above an inversion, and when they were reached by the afternoon mixing height. The data show quantitatively that initially the effluent from large chimneys tends to remain airborne longer than from small chimneys. |
