Impact of Urban Surface Roughness Length Parameterization Scheme on Urban Atmospheric Environment Simulation

Figure 1

Schematic representation of the urban canyon geometry in WRF-UCM. 𝑊_𝑅 is the width of building, 𝑊_𝐺 is the width of street, ℎ is the average building height, and 𝜎_𝐻 is the building height variability.
