气候变化条件下城市化对京津冀地区气温的影响
The effects of urbanization on the temperature over the Beijing-Tianjin-Hebei region under changing climate
摘要：
城市化对人类社会产生了巨大的影响。此外，全球变暖已成为一个越来越热门的话题，因为全球变暖不仅将在人类的日常生活中发挥重要作用，而且对全球气候产生巨大影响。在全球变暖的背景下，城市化的影响可能存在差异，这是本项目主要讨论的话题。利用1960-2014年北京市城区和郊区2个气象站不同下垫面条件下的月气温资料，分析了不同下垫面条件下的月气温变化特征。此外，还选取了1993年和2010年两个不同环流条件的年份，利用天气预报模式进行了模拟。利用天气研究与预报（WRF）模式，研究了不同环流条件下城市化对京津冀地区夏季气温的影响。结果表明，低压系统下的城市化效应大于高压系统下的城市化效应。这是因为1993年低压系统下，市区和郊区的总云量差异较大。该研究不仅可以加深对城市化效应的认识，而且可以为在全球气候变暖背景下提高防灾减灾能力提供科学依据。
英文摘要：
Urbanization has a large impact on human society. Besides, global warming has become an increasingly popular topic since global warming will not only play a significant role in human beings daily life but also have a huge impact on the global climate. Under the background of global warming, the impacts of urbanization may have differences, which is the topic this project mainly discusses. In this study, the monthly air temperature data from 2 meteorological stations in Beijing under the different underlying surface: urban and suburban for a period of 1960-2014 were analyzed. Besides, two years, 1993 and 2010, selected with the different circulation conditions have been simulated by weather forecasting models. We conducted experiments using the Weather Research and Forecasting (WRF) model to investigate the impacts of urbanization under different circulation conditions on the summer temperature over the Beijing-Tianjin-Hebei Region (BTHR). The results indicate that the effect of urbanization under low-pressure system is greater than that under high-pressure system. That is because the difference of total cloud cover between the urban area and the suburban area is greater under low-pressure system in 1993. This research will not only increase our understanding of the effect of urbanization but also provide a scientific basis to enhance the ability to prevent disasters and reduce damages under the global warming background.
