不懂UCM是神马。。。楼主赐教。。。
Urban Canopy Model (UCM)
In order to better represent the physical processes involved in the exchange of heat, momentum, and water vapor in urban environment in mesoscale model, an UCM is coupled to the WRF model. The main purpose of the coupled model is to improve the description of lower boundary conditions and to provide more accurate forecasts for urban regions. The UCM is a single layer model which has a simplified urban geometry. Some of the features of the UCM include, shadowing from buildings, reflection of short and longwave radiation, wind profile in the canopy layer and multi-layer heat transfer equation for roof, wall and road surfaces (Kusaka and Kimura, JAM, 2004). |
