Lower Urban Humidity Moderates Outdoor Heat Stress

AGU Advances, Год журнала: 2022, Номер 3(5)

Опубликована: Сен. 20, 2022

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.

Contrasting Trends and Drivers of Global Surface and Canopy Urban Heat Islands

Geophysical Research Letters, Год журнала: 2023, Номер 50(15)

Опубликована: Авг. 8, 2023

Abstract A comprehensive comparison of the trends and drivers global surface canopy urban heat islands (termed I s c trends, respectively) is critical for better designing mitigation strategies. However, such a remains largely absent. Using spatially continuous land temperatures air (2003–2020), here we find that magnitude mean trend (0.19 ± 0.006°C/decade, SE) 5,643 cities worldwide nearly six‐times corresponding (0.03 0.002°C/decade) during day, while former (0.06 0.004°C/decade) double latter at night. Variable importance scores indicate daytime slightly more controlled by property, background climate plays dominant role in regulating trend. At night, both are mainly climate.
