• Technical and practical inadequacy of the UHI concept critically reviewed. Proposed a novel system-based paradigm for re-conceptualized studies. Implications to urban planning policy making discussed. Past decades have seen drastically increasing research effort progress on study phenomenon heat island (UHI). Despite its simplicity, this convenient has promoted significant advances in scienti...

Urban heat islands (UHI) are a widely documented phenomenon that adversely increases urban overheating and, among other effects, contributes to heat-related mortalities and morbidities in areas. Consequently, comprehensive UHI-mitigating measures essential for improving microclimate environments contributing salutogenic design practices. This study proposed cooling strategies involving differen...

A rapid increase in urbanization has caused severe urban heat island (UHI) effects China over the past few years. Zhengzhou is one of emerging cities where residents are facing strong impact UHI. By utilizing MODIS data on land surface temperature (LST) and employing 3S technology, this study investigates UHI phenomenon a 10-year period (2012–2021), aiming to analyze spatio-temporal evolution c...

To assess and monitor the environmental dynamics on a regional or global scale, Land Surface Temperature (LST) has been estimated for South Mumbai, using Landsat data years 2000, 2010, 2015, 2020. The urban heat island (UHI) effect also assessed by analysing LST pattern in study area. normalized difference vegetation index (NDVI) analysis shows that UHI effects are less when cover is high. On c...

Background Urban heat island (UHI) effect, the ubiquitous consequence of urbanization, is considered to play a major role in population expansion of numerous insects. Cryptotympana atrata and Hyalessa fuscata are the most abundant cicada species in the Korean Peninsula, where their population densities are higher in urban than in rural areas. We predicted a positive relationship between the UHI...

During the last century, urban pollution has increased with the growth of cities. Urban air quality has become a high priority as it is directly linked to concerns such as human exposure and health. The present work is dedicated to urban air quality modeling with focus on urban meteorology. The main goal is to improve meteorological and air quality simulations in urban areas. Based on measureme...

One mechanism for climate change is the collected impact of changes in land cover or land use. Such changes are especially significant in urban areas where much of the world’s population lives. Satellite observations provide a basis for characterizing the physical modifications that result from urbanization. In particular, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on ...

Lisbon is a European Mediterranean city, greatly exposed to heatwaves (HW), according recent trends and climate change prospects. Considering the Atlantic influence, air temperature observations from Lisbon’s mesoscale network are used investigate interactions between background weather urban thermal signal (UTS) in summer. Days classified prevailing regional wind direction, hourly UTS compared...
