Coupling a Single-Layer Urban Canopy Model with a Simple Atmospheric Model: Impact on Urban Heat Island Simulation for an Idealized Case

摘要: We incorporated a single-layer urban canopy model into simple two-dimensional atmospheric in order to describe the fundamental impact of on an idealized heat island simulation. found that circulation developed less strongly than when using with standard slab model. Additionally, coupling (i) delays phase surface air temperature, (ii) reduces diurnal range and (iii) produces nocturnal island, which results from difference stability between city its surroundings. The features coupled agree well those observation, although does not. simulated is caused by larger storage releases sensible after sunset.
