Urbanization and its impact on Urban Heat Island Intensity in Chennai Metropolitan Area, India

REST framework: A modelling approach towards cooling energy stress mitigation plans for future cities in warming Global South

“…4 ), the higher population density sites were expected to experience a higher increase in temperature. A similar UHI induced temperature difference in this region was reported by ( Amirtham, 2016 ) for Chennai (2 °C–4.1 °C) and by Thomas, Sherin, Ansar, and Zachariah (2014 ) for Kochi (0.62 °C–4.18 °C). It indicated that the to-be -built smart city of Amaravati can experience UHI as per our estimation on urbanisation pattern (see Fig.…”

Urban Heat Island studies: Current status in India and a comparison with the International studies

“…The Brst paper on heat island intensity found was based on the temperature increase in Pune, Maharashtra in the year 2000 (Deosthali 2000). As mentioned above, majority of the studies are concentrated on the capital city, New Delhi (Mohan et al 2012;Pandey et al 2012;Babazadeh and Kumar 2015;Aslam et al 2017) and the other cities where UHI studies were carried out are Bangalore (Gopalakrishnan et al 2003;Ramachandra and Kumar 2010; Ambinakudige 2011), Mumbai (Grover and Singh 2015;Mehrotra 2018), Chennai (Gopalakrishnan et al 2003;Amirtham 2016), Pune (Deosthali 2000; Nesarikar-Patki and Raykar-Alange 2012), Hyderabad (Gopalakrishnan et al 2003), Ahmedabad (Joshi et al 2015;Goswami et al 2016), Visakhapatnam (Devi 2006), Ernakulam (Baby and Arya 2016;Thomas et al 2014), Bhopal (Gupta et al 2009), Bhubaneswar (Swain et al 2016), Noida (Kikon et al 2016), Kanpur (Chakraborty et al 2016), Lucknow (Singh et al 2017), Bathinda (Sharma and Pandey 2015), Guwahati (Borbora and Das 2014), Jaipur (Gupta 2012), Kolkata (Ali Gazi and Mondal 2018), Thiruchirappalli (Kannamma and Sundaram 2015) and Uttarakhand (Kumar and Singh 2016).…”

“…During winter, the heat intensity reached up to 4.6 C in pre-dawn and 3.7 C in the early night. A HOBO data logger (HOBO U10 Temp/RH), enclosed within a white perforated plastic box is deployed for measuring air temperature and relative humidity in the studies of Amirtham (2016). The UHI intensity was computed with the reference data available from Meteorological stations and they found that the maximum daytime temperatures were based on the urban morphology and the time at which the measurement location is exposed to incident solar radiation.…”

Comparative Vulnerability Assessment of Urban Heat Islands in Two Tropical Cities in Indonesia

“…[9] examined land surface temperature patterns and their relationship with land cover in Guangzhou and in urban clusters in the Zhujiang Delta, China and concluded from a remote sensing investigation that vegetation abundance is one of the most influential factors in controlling land surface temperatures. The temperature difference recorded in Chennai metro area was 3.6°C in summer and 4.1°C in winter [10]; Malaysia 3.9°C to 5.5°C [11]; Many previous studies have indicated that the UHI intensity was related to local meteorological conditions [2]. In Seoul, Korea, the most prominent occurrence of the maximum UHI intensity has a peak at 4.5°C when there is zero cloud cover [12].…”
