摘要本文探讨了半干旱环境下城市扩张对近地表气温和空调用电量的区域影响。除了现代城市景观设置外，还使用天气研究和预报模型结合多层建筑能源方案分析了两种预测的城市扩张情景。作者以高空间分辨率（1公里水平网格间距）模拟了亚利桑那州10天的极端高温期，亚利桑那州是美国增长最快的地区之一。结果表明，建筑物和路面对自然地表的替代显著提高了当地近地表平均气温。此外，在一些城市地区，目前来自交流系统的废热排放使夜间平均2米空气温度升高了1℃，但预计的城市发展使这种情况恶化，使夜间空气温度升高了1.5℃-1.75℃。人为的……
AbstractThis article explores regional impacts on near-surface air temperature and air conditioning (AC) electricity consumption due to projected urban expansion in a semiarid environment. In addition to the modern-day urban landscape setting, two projected urban expansion scenarios are analyzed with the Weather Research and Forecasting Model coupled to a multilayer building energy scheme. The authors simulate a 10-day extreme heat period at high spatial resolution (1-km horizontal grid spacing) over Arizona, one of the fastest-growing regions in the United States. Results show that replacement of natural land surfaces by buildings and pavement increases the local mean near-surface air temperature considerably. Furthermore, present-day waste heat emission from AC systems increases the mean nighttime 2-m air temperature by up to 1°C in some urban locations, but projected urban development aggravates the situation, increasing nighttime air temperatures by up to 1.5°–1.75°C. The contribution of anthropogenic...
