Z. Sorbjan et M. Uliasz, Large-eddy simulation of air pollution dispersion in the nocturnal cloud-topped atmospheric boundary layer, BOUND-LAY M, 91(1), 1999, pp. 145-157
Effects of stratocumulus clouds on the dispersion of contaminants are studi
ed in the nocturnal atmospheric boundary layer. The study is based on a lar
ge-eddy simulation (LES) model with a bulk parametrization of clouds. Compu
tations include Lagrangian calculations of atmospheric dispersion of a pass
ive tracer released from point sources at various heights above the ground.
The results obtained show that the vertical diffusion is non-Gaussian and
depends on the location of a source in the boundary layer.
