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.
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.
