Abstract Understanding the effect of building morphology on the flow aloft is important to the ventilation and pollutant removal in cities. This study examines the dynamics over hypothetical urban areas in isothermal conditions using wind tunnel experiments. Different configurations of rib-type and cube-type arrays are designed to model hypothetical rough urban surfaces. https://www.diegojavierfares.com/save-now-Caire-SeQual-Eclipse-Battery-Cartridge-for-Eclipse-3-5-Concentrators-top-grab/
