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 …

We experimentally investigate the effect of a typical building covering: the gable roof, on the
flow and air exchange in urban canyons. In general, the morphology of the urban canopy is …

A neutral boundary layer was generated in the laboratory to analyze the mean velocity field
and the turbulence field within and above an array of two-dimensional obstacles simulating …

A one-particle three-dimensional stochastic Lagrangian model fortransport of particles in a
horizontally-homogeneous atmosphericsurface layer with arbitrary one-point probability …

We present a new measure for the rotation of Lagrangian trajectories in turbulence that
simplifies and generalises that suggested by Wilson and Flesch (Boundary-Layer Meteorol …

Lagrangian and Eulerian statistics are obtained from a water-channel experiment of an
idealized two-dimensional urban canopy flow in neutral conditions. The objective is to …

Lagrangian stochastic (LS) models have shown to be a powerful technique to calculate
pollutant dispersion in complex flows. In this work, a three-dimensional LS model of …

Turbulent dispersion can be studied successfully by using Lagrangian particle models. In
general, the prediction of correct concentration fields is a complex issue when the turbulent …

Among well-mixed multi-dimensional Lagrangian stochastic (LS) dispersion models, we
observe that those in poorest agreement with observations produce 'spiralling …

A computational system composed of a three dimensional (3D) mesoscale model and a
Lagrangian stochastic model is applied to forecast the boundary layer dynamics and Carbon …
