Numerical Simulation of the Effect of Large Scale Wind on Urban Heat Island
大尺度环境风场对城市热岛效应影响的数值模拟试验

The Weather Research and Forecasting (WRF) model coupled with a single-layer Urban Canopy Model (UCM) is used to simulate the Urban Heat Island (UHI) features in Shanghai and Nanjing, two different cities in China. Results show that the horizontal distribution of UHI is determined by large-scale surface wind, which causes high air temperature of downstream rural area. Cross sections of the difference of air temperature between the urban and rural surfaces are analyzed, the model suggests that more heat is t...
