<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">ABSTRACT:</span>
<span style="font-family:"Arial",sans-serif">Buoyant plumes, propelled by concentrated heat and mass sources, are significant contributors to atmospheric pollution, affecting air quality, human health, and ecological systems. Originating from phenomena such
as fires, volcanic eruptions, and chimney smokestacks, they represent a crucial class of problems in atmospheric dynamics. The behavior of turbulent buoyant plumes is influenced by the characteristics of the plume source, topography, and background flow conditions.
The atmospheric boundary layer, which varies diurnally from a few hundred to several thousand meters in height, significantly impacts the background flow conditions and consequently the plume dynamics. Using large-eddy simulations, this study investigates
how the diurnal variations in atmospheric stratification affect the dispersal behavior of turbulent buoyant plumes in crossflows. The results indicate that variations in the ABL stratification significantly impact the plume's energy content and decay, leading
to distinctive patterns of dispersion, entrainment, and spread.<br>
