Evaluating the Spatial and Temporal Characteristics of Summer Urban Overheating through Weather Types in the Attica Region, Greece

In this study, we investigated the association between weather type (WT) and urban heat island intensity (UHII) in region of Attica (Greece). The application methodology resulted ten WTs over region. UHII was calculated for every hour day from 2008 to 2017, using a new air temperature dataset produced by Copernicus Climate Change Service. To obtain more definitive findings about relationship UHII, also used upper 5% (urban overheating, UO). UO estimated two time intervals (daytime nighttime) warm period (June–September). frequency distribution, as well spatiotemporal characteristics UO, were investigated. It found that amplified under WT2 during night, while WT10 mainly related increased magnitudes daytime all months. Furthermore, analysis results revealed effect is pronounced Athens especially at center. hot spots identified suburban rural areas. Therefore, may help with mitigation strategies climate adaptation measures environments.
