Abstract

Arid regions worldwide, and particularly in Saudi Arabia, have been experiencing intensifying atmospheric thermal stress in recent decades, with profound implications for public health and urban sustainability. This study systematically analyzed the variability and trends of thermal discomfort index (TDI) across six major Saudi Arabian cities from 1984 to 2024, employing POWER data and robust statistical techniques, including descriptive analysis, Mann-Kendall Test (MKT), Sen’s Slope (SS), Theil-Sen Slope (TSS), Pearson’s Correlation and Lagged Correlation analysis. Monthly TDI values showed notable seasonal variations, ranging from winter minimum of 10.9 °C to summer maximum of 29.4 °C, with inland cities such as Riyadh (13.9–25.4 °C), and coastal cities like Dammam (16.2–29.4 °C), experienced distinct patterns of thermal stress. Trend analysis confirmed significant TDI increases during summer and transitional months across all cities, with the strongest warming trends in Dammam (June: SS = 0.044 °C/year) and Madinah (August: SS = 0.039 °C/year). Correlation analysis highlighted temperature as the primary driver of discomfort, while humidity emerged as a critical amplifying factor, particularly in coastal cities. These findings reveal an escalating patterns of atmospheric thermal stress across arid urban landscapes, exacerbated by synergistic effects of warming and humidity. Importantly, this study highlights the necessity for targeted urban heat mitigation strategies and the formulation of evidence-based environmental health policies to enhance resilience in arid environments. By quantifying both immediate and delayed climatic influences on diurnal thermal discomfort, this study establishes a foundation for more adaptive and climate-resilient urban planning in regions at the forefront of global warming.

破解干旱地区40多年来大气热暴露模式对环境健康和城市空气质量的影响
近几十年来,世界各地的干旱地区,特别是沙特阿拉伯的干旱地区,一直在经历日益加剧的大气热应力,这对公共卫生和城市可持续性产生了深远影响。本文采用POWER数据和描述性分析、Mann-Kendall检验(MKT)、Sen’s Slope (SS)、Theil-Sen Slope (TSS)、Pearson’s Correlation (Pearson’s Correlation)和滞后相关分析等稳健统计技术,系统分析了1984 - 2024年沙特阿拉伯6个主要城市热不适指数(TDI)的变化和趋势。月TDI值表现出明显的季节变化,冬季最小值为10.9°C,夏季最大值为29.4°C,其中利雅得(13.9 ~ 25.4°C)等内陆城市和达曼(16.2 ~ 29.4°C)等沿海城市表现出明显的热应激模式。趋势分析证实,所有城市夏季和过渡月份TDI均显著增加,其中达曼(6月:SS = 0.044°C/年)和麦地那(8月:SS = 0.039°C/年)升温趋势最强。相关分析强调,温度是导致不舒服的主要因素,而湿度则是一个关键的放大因素,尤其是在沿海城市。这些发现揭示了干旱城市景观中不断升级的大气热应力模式,并因增温和湿度的协同效应而加剧。重要的是,这项研究强调了有针对性的城市热缓解战略和制定基于证据的环境卫生政策的必要性,以增强干旱环境中的恢复力。通过量化即时和延迟的气候对日热不适的影响,本研究为全球变暖前沿地区更具适应性和气候弹性的城市规划奠定了基础。

期刊介绍: Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health. It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes. International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals. Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements. This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
