Pollutant dispersion processes over complex terrain are much more complicated than over
flat areas, as they are affected by atmospheric interactions with the orography at different …

In this paper, the MicroSpray 3-D Lagrangian particle dispersion model is presented and
reviewed, and several validation studies are shown. Starting from its core, based on a 3-D …

An appropriate parametrization of turbulence is fundamental both in meteorological and
atmospheric dispersion models, in order to properly simulate the dynamics of the flow and of …

We tested several planetary-boundary-layer (PBL) schemes available in the Weather
Research and Forecasting (WRF) model against measured wind speed and direction …

The transport and diffusion processes of a tracer gas released near the ground in the Rhine
valley region, in Central Europe, during the 1992 TRACT field experiment, are simulated by …

Simulations of separated flow over smooth two-dimensional sinusoidal hills were performed,
for hills of varying aspect ratio, using the atmospheric model Regional Atmospheric …

To study the influence of complex terrain with different scales on the structure of near-
surface turbulence, the turbulence observational data from Semi-Arid Climate and …

Results from numerical simulations of tracer dispersion from a point source (an incinerator
plant) over complex terrain are presented. Different modeling chains are used and model …

Three different modelling techniques to simulate the pollutant dispersion in the atmosphere
at the microscale and in presence of obstacles are evaluated and compared. The Eulerian …

An urban boundary layer model (UBLM) is improved by incorporating the effect of buildings
with a sectional drag coefficient and a height-distributed canopy drag length scale. The …
