Urban heat island (UHI) is a widely concerned urban climate which impacts billions of residents worldwide. Nevertheless, inadequate rigorous air temperature (Tair) measurement has become an obstacle to UHI research and mitigation, especially in megacities like Beijing. In this study, we applied 1-km hourly Tair dataset interpolated from records 521 stations The enables us analyze patterns on block scale the landscapes combined with local zones (LCZ) scheme. Our results indicate that: (1) its temporal variation each LCZ vary significantly, are highly relevant their morphology thermal-radiative properties. (2) 1 2 have highest nocturnal intensities (UHII). Discrepancies among LCZs also cause various variations UHII. (3) spatial pattern affects regional temperature. Area ratio aggregation extent 1&2 show significant positive correlations temperature, while A&D&G opposite regularity. (4) Distinct mitigation strategies put forward for subarea Beijing endowments population structure. study provides insight into plausible advice

Abstract Anthropogenic climate change has amplified human thermal discomfort in urban environments. Despite the considerable risks posed to public health, there is a lack of comprehensive research, evaluating spatiotemporal changes and its characteristics hot-hyper arid regions, such as Arabian Peninsula (AP). The current study analyzes categories their AP, using newly developed high-resolution gridded ERA5-HEAT (Human thErmAl comforT) dataset for period 1979–2022. In addition, assesses interplay between Universal Thermal Climate Index (UTCI) El Niño-Southern Oscillation (ENSO) indices period. results reveal significant increase characteristics, with higher spatial variability AP region. major centers southwestern, central, southeastern parts have experienced increases (0.4–0.8 °C), frequency intensity stress during temporal distribution demonstrates linear UTCI frequencies intensities, particularly from 1998 onward, signifying transition towards hotter characterized by frequent, intense, prolonged heat conditions. Moreover, ENSO exhibit dipole pattern correlation positive (negative) southwestern (eastern parts) AP. study’s findings suggest that policymakers planners need prioritize health well-being AP’s areas, especially vulnerable groups, implementing adaptation mitigation strategies, carefully designing future cities mitigate effects stress.

Climate change has become an emerging topic, leading to widespread damage. However, when considering climate, attention is drawn various scales, and urban microclimate emerged as a trending subject due its direct relevance human living environments. Among the microclimatic factors, temperature precipitation are utilized in order identify trends. The identification of changes from ground stations poses difficulties lack well-distributed stations; thus, satellite-based products gaining popularity. satellite were validated against data, following which time-series spatial analyses conducted. rainfall anomaly index, seasonality heat wave magnitude mean differ Colombo Metropolitan Area compared entire country. Each index calculated decadal-wise By utilizing four climate indices, analysis endeavors investigate surrounding areas such Western Province This study aids local authorities mitigating by enhancing city resilience. These findings underscore importance understanding addressing impacts on extremes mitigate potential adverse effects activities environment. Understanding specific reasons for anomalies often necessitates extensive modeling data analysis.
