[M-IS13] Regional and global urban climate processes across multi-temporal scales

Throughout history, the development of cities has been deeply intertwined with their surrounding geography and climate. The distinct climatic features of urban areas were formally documented as early as the 19th century by figures like Luke Howard, who studied London's climate. Today, rapidly expanding global cities are increasingly recognized both as powerful shapers of weather and as highly vulnerable areas facing the intensification of climate extremes. Significant advances in long-term observations and multi-scale climate models are being utilized to better understand and manage complex urban-climate interactions. Given their role as key players in climate change, cities have received special emphasis from organizations like the Intergovernmental Panel on Climate Change (IPCC). What new insights are emerging regarding urban climate dynamics at the regional to global scale? What advancing methods allow for the investigation of urban climate interactions beyond the scope of single cities? How do we precisely define the role of urban climate in the broader context of global climate change? This session will focus on urban climate across multiple scales, acknowledging the unique position cities hold to both shape and be modified by changing background climate.

We welcome submissions on the following topics:

* Physical mechanisms of urban climate;
* Quantification and attribution of the urban effect on climate and the reciprocal impact of climate change on cities;
* Novel approaches to urban climate research;
* Urban climate in the context of global climate change;
* Regional and global-scale modeling and observations of urban climate;
* Atmospheric chemistry over urban areas;
