As an effect of climate change, cities need detailed information on urban climates at decision
scale that cannot be easily delivered using current observation networks, nor global and …

The atmospheric boundary layer mediates the exchange of energy, matter, and momentum
between the land surface and the free troposphere, integrating a range of physical …

This study presents numerical simulations analysing the effect of urban heat island (UHI)
mitigation measures on the chemical composition of the urban atmosphere. The mesoscale …

This study compared the diurnal and seasonal cycles of atmospheric and surface urban heat
islands (UHIs) based on hourly air temperatures (Ta) collected at 65 out of 262 stations in …

This study examines the statistical predictability of local wind conditions in a real urban
environment under realistic atmospheric boundary layer conditions by means of Large-Eddy …

Cold environment supports a large diversity of local climates. Among them, urban climates in
northern cities stand out for their pronounced warm temperature anomaly known as the …

The mean flow and turbulence within a regular building array are analysed for a wide range
of bulk Richardson numbers, Rb, using large-eddy simulation. Time-averaged streamlines in …

Conventional footprint models cannot account for the heterogeneity of the urban landscape
imposing a pronounced uncertainty on the spatial interpretation of eddy-covariance (EC) flux …

Mean wind profiles within a unit-aspect-ratio street canyon have been estimated by solving
the three-dimensional Poisson equation for a set of discrete vortex sheets. The validity of this …

Winter smog episodes are a severe problem in many cities around the world. The following
two mechanisms are responsible for influencing the level of pollutant concentrations …
