</span><span style="font-size:12.0pt;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>
