“…LCZ system was previously used to study UHI phenomenon during "ideal days" or on seasonal and annual level (Siu and Hart 2013;Alexander and Mills 2014;Lehnert et al 2015;Fenner et al 2014;Unger et al 2014;Leconte et al 2015;Leconte et al 2017;Skarbit et al 2017;Lehnert et al 2018;Yang et al 2018). Furthermore, LCZ system was applied for mapping (Unger et al 2011;Bechtel and Daneke 2012), development of urban meteorological networks (UMNs) (Lelovics et al 2014;Šećerov et al 2015;Caluwaerts et al 2020), analysis of surface temperatures (Skarbit et al 2015;Gémes et al 2016;Geletič et al 2016a;Geletič et al 2019;Gholami and Beck 2019), outdoor thermal comfort (Kovács and Németh 2012;Puliafito et al 2013;Milošević et al 2016;Unger et al 2018;Kotharkar et al 2019), urban climate modeling (Brousse et al 2016;Geletič et al 2016bGeletič et al , 2018, and urban planning (Middel et al 2014;Perera and Emmanuel 2018). This indicates LCZ system applicability in urban climate studies.…”

A comprehensive analysis of air temperature (T a ) dynamics in "local climate zones" (LCZs) of Novi Sad (Serbia) was based on measurements from 17 stations during 3 years. Hourly changes of T a , cooling rates (CR), heating rates (HR), and urban heat island (UHI) intensity were assessed on seasonal and annual level and during heat wave (HW) and cold wave (CW) periods. Substantial differences are observed for minimum (T min ) and mean temperatures (T mean ) between LCZs. Two-phase nocturnal cooling was recognized with the first cooling phase characterized by intensive LCZ dependent cooling starting at 1-3 h before sunset and lasting until 3-4 h after sunset. The second cooling phase lasts until sunrise and is characterized by less intensive and LCZ nondependent cooling. The most intensive cooling (CR peak ) was observed in first cooling phase of HW and ranged from − 1.6°C h −1 in street canyon (LCZ 2) to − 3.9°C h −1 in forest (LCZ A). Furthermore, a new cooling indicator (CR total ) was introduced. Due to cooling differences, the most intensive UHI of 5.5°C was noticed between LCZs 2 and A at sunset + 1 h during HW. Two-phase diurnal heating was also recognized in LCZs with the first heating phase characterized by intensive LCZ dependent heating starting at sunrise and lasting until 4-7 h afterwards. The most intensive heating (HR peak ) ranged from 2.0°C h −1 in street canyon to 3.0°C h −1 in industrial area (LCZ 8) during HW. The second heating phase lasts until sunset and is characterized by less intensive heating and smaller HR differences between LCZs.

“…Some studies have considered assessing thermal comfort on the street level. However, in these studies, the streets are analyzed as singular locations rather than on the microscale of individual streets (Banerjee et al, 2022;Kotharkar et al, 2019;Manavvi & Rajasekar, 2020). Very few studies have assessed PTC on sidewalks and the impact of urban geometry and microclimate on pedestrians while walking (Chidambaranath & Bitossi, 2018;Deevi & Chundeli, 2020).…”

Walking can be an efficient and sustainable mode of transportation for "last mile" connectivity. However, the willingness to walk largely depends on the availability of infrastructure, safety, and comfort. Improving thermal comfort on streets connected to transit stations is crucial for encouraging walking and public transit use. This study assesses seasonal and spatiotemporal variations in pedestrian thermal comfort (PTC) on an N-S-oriented street in Nagpur (India). Thermal walk surveys simultaneously monitored environmental conditions and human thermal perception (thermal sensation vote-TSV). The findings revealed that urban geometry significantly influences PTC and TSV, and the level of influence varied spatiotemporally in both seasons. This study shows the relationship between urban street geometry, microclimate, and PTC, emphasizing the necessity of a multidimensional assessment approach.

“…The active years of cluster #3, urban form, were 2012 to 2020. Related research mainly used LCZ to study the impact of urban-scale geometric forms on the urban thermal environment [73][74][75], and there are few relevant strategic studies. Javanroodi simulated 1600 city layouts and proposed the best urban form for potential ventilation [76].…”

Knowledge Map of Urban Morphology and Thermal Comfort: A Bibliometric Analysis Based on CiteSpace

In the context of global climate change, urban morphology is closely related to thermal comfort and contributes to sustainable urban development. Academics started to pay attention to related topics and carried out many studies during the last decades. This paper aims to summarize the research achievements and the development track for future studies. The Web of Science database and CiteSpace were used in this paper to conduct a bibliometric analysis of 556 studies in related fields from 1993 to 2020. Using a three-level co-occurrence analysis of 446 keywords, 1187 cocited literature clusters, and 15 landmark studies, the research topics and mainstream research frameworks were identified. The results show that with the increasing participation of disciplines such as computer science, ecology, and chemistry, the purpose of future research will shift to a focus on anthropogenic heat emissions, energy consumption, air pollution, and other aspects, and new research tools will be needed. In addition to building-scale and block-scale morphology, urban-scale morphology and green infrastructure will become the focus in the future. This study provides a systematic review of research about urban morphology and thermal comfort, which can inspire other researchers and policy makers.
