关于LCZ地图的获取,有两种方式: LCZ生成器,仅能代表2017-2019 年。 全球LCZ地图,2018年。 详细信息可参考https://www.wudapt.org/lcz-maps/ LCZ生成器较为麻烦,但具有自主性,可以自由设置;全球的LCZ地图比较简单,但可能会有一些时间上的限制,比如一般都是哪一年的LCZ地图。拥有了LCZ地图之后,我们就可以利用它来...
WRF-UCMAccurate simulation of urban near-surface air temperature (SAT) is essential for understanding climate dynamics. The reliability of the simulated SAT depends largely on the representation of urban morphology. Local Climate Zones (LCZ), as a sort of urban morphology representation, have been ...
Correct net long wave fluxes for application in modeling urban climate using Single Layer Urban Canopy Model (SLUCM). It slightly improved 2-m temperature in urban area.Details Change the behavior of the mp_zero_out flag so that it affects only the 'moist' array, whereas previously it also...
In both the UCM and BEP, the mean building and street width were calcu- lated through the weighted average based on the total building length and street length in each grid cell, respectively. The total building length was estimated as the ratio of building area and building width, where ...
Urban climate modeling UCM BEP Urban land use Urban canopy parameter Chinese cities 1. Introduction Urbanization largely affects the local climate in cities through the change of land use and emissions of anthropogenic heat and air pollutants (Arnfield, 2003). The urban area is usually warmer, drie...
随着世界城市数据库和访问门户工具(WUDAPT)的出现,LCZ地图开始应用在WRF-UCM中。与传统的将城市类型分成三类相比,它将城市类型分为11类,分的更为细致: 在WRFv4.4.2之前,LCZ1-10在WRF-UCM土地利用类型中主要对应31-41,但是这种分类方法与NLCD,即美国国家土地覆盖数据集重复,因此WRFv4.4.2版本之后,LCZ1-10在WRF...
WUDAPT是一个全球性的项目,旨在创建一个关于城市地区气候特征的综合数据库。它通过将城市划分为不同的局部气候区(LCZ)来实现这一点,每个LCZ都有其独特的地表特性、建筑密度和高度等特征。 安装 w2w对环境的有些要求,尤其是numpy库的版本,建议新建环境安装。
In general, the WRF-UCM model possesses the capability to reliably simulate heatwave episodes and would be adopted to evaluate the effectiveness of various mitigation strategies in alleviating the impacts of urban heat. The spatial distribution of T2 using both LCZ-UCP and gridded-UCP is depicted ...
A WUDAPT based Local Climate Zone (LCZ) map is drawn to replace and supplement the default underlying surface data to execute WRF-UCM coupled simulations. After examining the accuracy of the WRF-UCM simulation, the mean wind speed profiles, turbulence intensity profiles and power spectra of ...
