Figure 2
Diagram of the single-layer urban canopy model (SLUCM): ZT is the roughness length for heat, ZR (h) is the mean building height, Za is the bottom layer height of the parent NWP model, TR, TW, and TG are roof, wall, and ground temperature, Ta is the air temperature at Za, TS is the temperature defined at height ZT + d, HR represents the sensible heat flux from roof to the atmosphere, HW and HG are sensible heat flux from wall and ground to the urban canyon space, H is the weight-mean sensible heat flux at Za, and Wroof and Wroad are the width of roof and road.
