Localities' experience with extreme precipitation and their climate planning status is also compared with a selection of socio-demographic indicators. For the region analyzed, climate-focused planning is relatively rare, but coastal communities experienced more frequent extreme precipitation events and appear to have engaged in more climate-focused planning relative to riverine communities and also are more likely to cite scientific evidence of climate change as justification for planning. Notably, some coastal communities engaged in climate-related planning despite having a higher proportion of Republican voters, who are typically more conservative and skeptical of both climate change and public policy efforts to address it. Finally, some storms, even when not climatologically extreme, nonetheless leave a lasting impression because of their impacts. These have significant implications for local efforts to address climate challenges, showing how extreme climatological events may drive government decisions and highlighting additional factors that may also amplify or impede planning for climate change.</div></div>","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"59 ","pages":"Article 102258"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on sensitivity experiments, it quantitatively analyzed the impact of LU and AH inputs on regional climate and OTC in Beijing during winter and summer. OTC was assessed using physiologically equivalent temperature (PET) and the universal thermal climate index (UTCI). The results indicate that urban LU significantly enhanced outdoor heat stress in summer, although the humidity-reducing effect of LU mitigated this impact partially. In contrast, LU caused notable temperature decreases and humidity increases in winter, which exacerbated the intensity of cold stress expressed by PET. It decreased by 0.32 °C during the daytime and 1.83 °C at night, despite lower wind speeds having an offsetting effect. The overall influence of AH was relatively subdued, consistently resulting in elevated temperatures and wind speeds, yet reduced humidity, with more pronounced effects observed during nighttime and winter.

The results indicate that adding bus stations in previously unserved urban areas can lower CO and NO<sub>2</sub> levels, but may increase PM10 and PM2.5 concentrations. To best reduce CO and NO<sub>2</sub> concentrations, the optimal distances between adjacent stations should be 1500 m and 1250 m, and the optimal densities are 5 stations within a 2000 m radius and 2 stations within a 1250 m radius, respectively. Besides, the highest increases in PM10 and PM2.5 concentrations occur where 3 stations are within a 2000 m radius, warranting attention.

By systematically evaluating key physical and social factors—such as population density, impervious surfaces, elevation, and rainfall intensity—the research identifies high-risk flood-prone areas, particularly in central districts like Al-Jimi and Al-Muwaiji. GIS spatial modeling, supported by remote sensing data, enabled the generation of a detailed vulnerability map, categorizing zones into low, medium, and high-risk categories. The findings reveal that dense urbanization, low elevation, and inadequate drainage infrastructure significantly increase vulnerability. Conversely, areas with higher elevations and natural vegetation, like Jebel Hafeet, exhibit resilience. The methodology's robustness lies in its integration of diverse data sources, weighted overlay analysis, and pairwise comparisons, ensuring precision in identifying and prioritizing mitigation strategies.
