Abstract Surface temperature is often used to examine heat exposure in multi‐city studies and for informing urban mitigation efforts due scarcity of air measurements. Cities also have lower relative humidity, traditionally not accounted large‐scale observational risk assessments. Here, using crowdsourced measurements from over 40,000 weather stations ≈600 clusters Europe, we show the moderating effect this urbanization‐induced humidity reduction on outdoor stress during 2019 heatwave. We demonstrate that daytime differences index between their surroundings are weak, associations urban‐rural difference with background climate, generally examined surface perspective, diminished moisture feedbacks. spatial variability temperature, within these clusters—relevant detecting hotspots potential disparities exposure—and find a poor proxy intra‐urban distribution daytime. Finally, vegetation shows much weaker (∼1/6th as strong) than which has broad implications optimizing strategies. These findings valid operational metrics shaded conditions (apparent humidex), thermodynamic proxies (wet‐bulb temperature), empirical indices. Based evidence, lack better alternatives, may be suitable accurately strategies across cities, necessitating more urban‐scale observations urban‐resolving models.

Abstract Urbanization has become a prominent anthropogenic activity globally, resulting in the substantial modification of temperature and rainfall around urban areas. Studies also indicate that exhibits an asymmetrical shift from light to extreme rainfall, causing both floods droughts over different parts globe. However, what extent urbanization influences changes drought remains understudied. Accordingly, we provided investigation effects on events statistical model‐based perspectives. Results showed generally increased heavy decreased rainy season five agglomerations (i.e., Yangtze River Delta [YRD], Middle Region [MRYR], Chengdu‐Chongqing, Guizhou, Yunnan) Basin during 1981–2020. Specifically, contributed 42.7% 30.8% increases MRYR YRD while 30.6% contribution decrease rainfall. Interestingly, results suggested regions were more prone due urbanization. Nevertheless, found some variabilities across areas interactions with complex terrains climate patterns. Further simulations using Weather Research Forecasting model confirmed our findings helped understand potential underlying mechanism. The current research is expected provide scientific knowledge for better planning preparedness urbanization‐induced hazards.

Abstract Understanding how urbanization affects compound hot extremes (CHEs) is important for the sustainable development in urban agglomeration under global warming. In this study, we investigate changes of CHEs summer over Beijing‐Tianjin‐Hebei region (BTH), Yangtze River Delta (YRD) and Pearl (PRD) China, assess effects on these changes. We find that frequency intensity show significantly increasing trends agglomerations recent five decades, particularly megacities such as Beijing, Shanghai, Guangzhou Tianjin. The contributions to YRD PRD were estimated 36 ∼ 58%, while relatively small BTH, ranging 16 29%.

Accurately identifying the key areas of urban heat islands (UHIs) is crucial for effectively mitigating UHI effect. Current research has mainly focused on independent island patches while neglecting impact their interconnectivity effects. To address this gap, we conducted a study constructing networks from connectivity perspective. First, used morphological spatial pattern analysis (MSPA) to identify sources and evaluate significance. Subsequently, using land use data, constructed thermal diffusion resistance surface assessed its characteristics. Finally, applied circuit theory corridors nodes among sources. The main area Harbin was as area, following findings were obtained: (1) identified total 36 source areas, which 2 categorized having highest importance level 9 second-highest level. (2) distribution in exhibited distinct north–south pattern, with higher values obtained north lower south. (3) We 71 heat-connected 35 nodes, most located northern part area. These results hold significant theoretical practical implications alleviating regional UHIs enhancing climate adaptation capacity.

Owing to amplified impacts on human society and ecosystems, compound events (or extremes) have attracted ample attention in recent decades. China is particularly vulnerable due the fast warming rate, dense populations, fragile ecological environment. Recent studies demonstrated tangible effects of climate change with mounting economy, agriculture, public health, infrastructure China, posing unprecedented threats that are increasingly difficult manage. Here, I synthesize progress associated China.
