Miao Yu, PhD


In the recent 30 years, the city of Beijing has experienced an unprecedented rapid urbanization process. Surface land use change and anthropogenic heat emissions induced by urbanization are the primary human activities affect the global climate change. Urbanization is a local scale phenomenon, but urban can influence regional climate through changing atmospheric composition, circulation system and water cycle. Correctly understanding the impact of land-use and taking urbanization into account in climatic prediction have potential applications and significance in science.

The Beijing meteorological tower (325m) is located in the north Beijing a region that has developed from a suburban to an inner city setting over the past 30 years. Based on a study of observational data from this tower and model simulations, we assessed inter-annual and inter-decadal variation of meteorological elements on the boundary layer in Beijing, extracting the contributions of urbanization from climate change. The urbanization mainly contributes to the temperature increase in the afternoon and nighttime and dominates the increase in daily mean near-surface temperature. In addition, the impact of urbanization on precipitation mechanisms are investigated. The influence of urbanization on heavy rain is the most significant and plays a significant role in frontal-type rainfall.


Miao_Yu_PhDMiao Yu graduated with her Bachelor’s degree from Lanzhou University (China) in Atmospheric Science, later got her PhD degree from Institute of Atmospheric Physics, Chinese Academy of Sciences with a thesis focusing on the climate effect of urbanization. After that, she got a position as researcher at Institute of Urban Meteorology, China Meteorology Administration to study urban-impact on boundary layer structure and improve operational urban weather forecasting systems.
