人为热释放对我国西南地区复杂地形下气候影响及机理研究

近百年来，人类活动对全球气候产生了深远的影响。人为热释放是形成城市气候重要因子，随着城市化进程的加剧，其加热效应对气候影响将更显著。本研究在考虑城市化加剧的背景下，考虑我国西南地区复杂地形，研究人为热释放加热效应随着城市化发展，对我国西南地区气候的影响及反馈机理。本研究的主要内容是考虑我国西南地区复杂地形，应用先进的高精度全球变网格气候模式VR-CESM，建立人为热释放加热效应的模式参数化方案，应用到VR-CESM，综合考虑大气、陆面、海洋和海冰的相互作用和反馈，数值模拟和评估人为热释放对我国西南地区大气环流，水汽输送，云降水、能量收支，地表温度等气候因子的影响。本项目对于研究我国西南地区气候变化，尤其是夏季暴雨、高温等极端天气和气候变化的机理研究具有非常重要科学意义和研究价值。

Human activities are considered as the main factor for global climate change in the recent 100 years. The heating effect due to Anthropogenic Heat Release (AHR) is an important factor for urban climate. With the development of global urbanization, its climatic effect will be more pronounced. This research work focuses on the climatic effects of the heating effect due to AHR on Southwest China under the condition of increasing urbanization and complex terrain. This research focuses on the estimation of annual global high-resolution distribution of AHR, and its parameterization for climate models and its application in advanced Variable Resolution-Community Earth System Model(VR-CESM). Considering the special terrain of Southwest China, the assessment of the impact of urbanization-induced heating effect caused by AHR on the climate in Southwest China will be finished. Its influence on the regional atmospheric circulation, water vapor transport, precipitation, energy balance, surface temperature, humidity (and so on) will be analyzed in detail. The research work is very important for the research on climate change in Southwest China, especially in the physical mechanism research on the extreme weather such as summer heavy rainfall and heat waves in Southwest China.
