A numerical model which can compute air temperature, specific humidity and wind velocity distribution within a single district of few square kilometers was developed by adding the effect of urban building and the forest canopies to a mesoscale turbulent closure model. The effects of anthropogenic heat are also accounted for in the model. The new model was tested with different kinds of canopies. Results of computations indicated that temperatures of the ground surface and walls of buildings depend much on the building density. The validation of the model, conducted using observational data, indicates that the model is capable of computing the wind velocity and air temperature in the urban area with resonable accuracy. The comparison of the results of the new model with existing models on the urban climate indicates that the new model can produces more realistic results.

通过将城市建筑和森林冠层的影响添加到中尺度湍流闭合模型中，建立了可以计算几平方公里的单个区域内的气温、比湿度和风速分布的数值模型。模型中还考虑了人为热量的影响。新模型使用不同类型的顶篷进行了测试。计算结果表明，地表和建筑物墙壁的温度很大程度上取决于建筑物的密度。使用观测数据进行的模型验证表明，该模型能够以合理的精度计算城市地区的风速和气温。将新模型与现有城市气候模型的结果进行比较表明，新模型可以产生更加真实的结果。
