Effects
of meteorology on plume dispersion:
Meteorology plays an important role in the dispersion of effluents. Various
meteorological factors affect the dispersion of emission into the atmosphere
in a variety of ways. One of the most important meteorological variables
responsible for high ground level concentrations is the height of thermal
boundary layer (or mixing height).
The following figure shows different situations of plume mixing in the
atmosphere as a result of the development of the thermal boundary layer
during a typical day. The figure shows that at 9 AM convective eddies pull
the pollutant to the ground. The spread of the plume is also restricted
in vertical due to the thermal boundary height at this time.
