| 摘 要： | 考虑了城市峡谷的阴影和辐射吸收效应，对城市的热容量、位温分布、辐射量以及感热通量进行了数值模拟，结果表明，白天城市峡谷使城市热容量更大，夜晚城市呈现中性大气边界层，城市峡谷是城市感热通量的主要来源，因此，在研究城市气象时不能忽略城市峡谷的影响。

| Abstract: | The urban heat capacity, potential temperature, radiant quantity and sensible heat flux are numerically simulated in consideration of heating/cooling of sunlit/shaded surfaces and radiation trapping effects in street canyons and heat store in building. Urban canyon enlarges urban heat capacity more greatly in daytime and there exists neutral layer in night. Urban canyon is the main source of urban sensible heat flux. Thus,urban canyon can not be neglected in the urban weather research. |
