Numerical fluid flow and heat transfer simulations of a three-dimensional idealized urban
environment are performed to investigate the effect of realistic non-uniform thermal forcing …

Urban heterogeneity, such as the variation of street layouts, building shapes, and building
heights, cannot be fully represented by density parameters commonly used in idealized …

We conducted large‐eddy simulations over 98 urban arrays with varying building densities
and height distributions. Compared with uniform‐height urban arrays, the influence of height …

Urban canopy parametrizations designed to be coupled with mesoscale models must
predict the integrated effect of urban obstacles on the flow at each height in the canopy. To …

Mesoscale climate models provide indispensable tools to understand land‐atmosphere
interactions over urban regions. However, uncertainties in urban canopy parameters (UCPs) …

In this study, a series of large-eddy simulations are conducted to explore the dynamics of
turbulence within the urban canopy. Two idealized urban-like geometries (staggered and …

In mesoscale climate models, urban canopy flow is typically parameterized in terms of the
horizontally averaged (1-D) flow and scalar transport, and these parameterizations can be …

Abstract Effects of solar position and of the ratio of buoyant to inertial forces on flow
properties (wind speed and temperature) within an array of urban-like obstacles are …

This review focuses on progress and emerging challenges in experimentally validated
modeling of microscale urban thermal environments over the last two decades. In the last …

Urban canopy models (UCMs) represent the exchange of momentum, heat, and moisture
between cities and the atmosphere. Single-layer UCMs interact with the lowest atmospheric …
