Studying the microclimate of plant canopies has long motivated scientists in various
research fields such as agronomy, ecology or silviculture, and almost a century has passed …

Air pollution in cities, intensified by vehicular traffic emissions and reduced ventilation, poses
a significant health risk. Obstacles, like solid or vegetation barriers, are being considered as …

Proper orthogonal decomposition (POD) is implemented to the atmospheric surface layer
(ASL) over real urban morphology based on the data of large-eddy simulation (LES) with …

Greening cities is a key solution to improve the urban microclimate and mitigate the impact
of climate change. However, the effect of tree planting on pollutant dispersion in streets is …

Winds are the basic forces for atmospheric transport such as pollutant removal and
pedestrian thermal comfort. The transport capability is commonly measured in terms of …

Large-eddy simulations are conducted to contrast momentum and passive scalar transport
over large, three-dimensional roughness elements in a turbulent channel flow. Special …

Atmospheric surface layer (ASL) consists of the inertial sublayer (ISL) and the roughness
sublayer (RSL) with different dynamics. This study characterizes the ASL flows over real …

Amplitude modulation (AM) quantifies the top-down interactions between the large-scale
motions (LSMs) in the outer layer and the near-ground turbulence structures. They are …

The presence of vegetation within urban canyons leads to non-trivial patterns of the
concentration of airborne pollutants, as a result of the complex structure of the velocity field …

Various drag-porosity models for urban buildings have been developed to explain the
changes caused by building layout on airflow and turbulence in urban neighborhoods. One …
