本文用一个二维数值模式来确定中纬度城市气候对加热和地面粗糙度的敏感性。考虑冬季夜间条件。人工加热是控制城市温度场的主要因素，粗糙度是控制风场的主要因素。目前的热添加率被发现使城市空气变暖2至4K。模型的结果与蒙特利尔的观测数据进行了比较。不同的热量添加和使用绿化带的高度的影响也进行了检查。
A two-dimensional numerical model is used to determine the sensitivity of the urban climate of mid-latitude cities to heat addition and surface roughness. Nocturnal winter conditions are considered. Artificial heating is found to be the major factor in controlling the urban temperature field, and roughness the controlling factor for the wind field. Present rates of heat addition are found to warm the urban air by 2 to 4K. Results from the model are compared with observational data for Montreal. The effects of varying the heights of heat addition and the use of greenbelts are also examined.
