标题： Undulating patterns of Hysteresis loops in diurnal seasonality of air temperature in Urban Heat Island effect: Insights from Paris and Madrid

摘要： 本研究通过对比分析巴黎和马德里两地的空气温度滞回模式，探讨城市热岛（UHI）效应的动力学特性。这两座主要欧洲城市具有不同的气候和城市特征。利用2008年至2017年以三小时为间隔的高分辨率模拟空气温度数据，我们研究了昼夜和季节性滞回环如何揭示UHI变化的独特性和普遍性方面。位于温带海洋性气候中的巴黎和位于寒冷半干旱区的马德里，在UHI强度、季节分布和昼夜模式方面表现出显著差异。尽管存在这些差异，这两座城市都表现出非常相似的滞回环方向和斜率，这表明太阳辐射和热量储存等时间依赖机制在不同城市背景下基本决定了空气温度的UHI。我们的研究结果强调了在制定有针对性的、具有气候适应能力的城市策略时，需要考虑本地气候和普遍的物理过程。这些结果为基于群体的干预措施和通过滞回模式对城市进行分类提供了途径，以指导城市规划和热缓解工作。 显示英文摘要

摘要： This study examines the dynamics of the urban heat island (UHI) effect by conducting a comparative analysis of air temperature hysteresis patterns in Paris and Madrid, two major European cities with distinct climatic and urban characteristics. Utilizing high-resolution modelled air temperature data aggregated at a fine temporal resolution of three-hour intervals from 2008 to 2017, we investigate how diurnal and seasonal hysteresis loops reveal both unique and universal aspects of UHI variability. Paris, located in a temperate oceanic climate, and Madrid, situated in a cold semi-arid zone, display pronounced differences in UHI intensity, seasonal distribution, and diurnal patterns. Despite these contrasts, both cities exhibit remarkably similar hysteresis loop directions and slopes, suggesting that time-dependent mechanisms such as solar radiation and heat storage fundamentally govern air temperature UHI across diverse urban contexts. Our findings underscore the importance of considering both local climate and universal physical processes in developing targeted, climate-resilient urban strategies. The results pave the way for group-based interventions and classification of cities by hysteresis patterns to inform urban planning and heat mitigation efforts.
