BACKGROUND Prior studies from around the world have indicated that very high temperatures tend to increase summertime mortality. However possible effect modification by urban micro heat islands has only been examined by a few studies in North America and Europe. This study examined whether daily mortality in micro heat island areas of Hong Kong was more sensitive to short term changes in meteor...

To further evaluate the factors influencing public heat and air-quality health, a characterization of how urban areas affect the thermal environment, particularly in terms of the air temperature, is necessary. To assist public health agencies in ranking urban areas in terms of heat stress and developing mitigation plans or allocating various resources, this study characterized urban heat in Cal...

The urban heat island (UHI) phenomenon has become a serious problem in recent years. It is necessary to study the mitigation methods and quantify their effects on UHI. In this paper, based on the remote sensed data, an empirical model was established as a negative function of land surface temperature (LST) to vegetation coverage. Urban heat island intensity (UHII) was estimated by a robust stat...

Seasonal differences in the Moscow urban heat-island intensity (UHII) have been studied detail based on data obtained 2018–2020 by meteorological network of stations located and region. It is shown that annual cycle this phenomenon slightly pronounced. In most cases, UHI manifested stronger summer weaker winter; however, some months, situation may be reverse. The question statistical significan...

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 UH...

Few publications have considered the urban heat island (UHI) effect in small settlements. This paper, therefore, presents findings of a UHI study conducted small, mid-latitude city Inverness, Scotland (population: 63,220). The aimed to provide an initial appraisal scale phenomena Inverness and understand factors associated with its presence. Mobile vehicular traverses transect were on 30 dates ...

An urban heat island phenomenon has increased in the last decades due to rapid urbanization, resulting a significant impact on local climate. In this study, remote sensing data was used analyze Spatiotemporal patterns of Urban Heat Island Intensity (UHII) over 20 years period semi-arid climate area. The relationship between Land Surface Temperature (LST), vegetation and Cover Types (LCTs) were ...

Based on the hourly temperature and precipitation data from China national meteorological stations regional automatic weather in Shenyang, relationship between extreme (ExHP) urban heat island Intensity (UHII) is analyzed. Results show that UHII higher at night early morning. The ExHP events mostly occur summer when relatively high. spatial distribution of Shenyang consistent with economic deve...

Abstract. Unprecedented urbanization in China has led to serious urban heat island (UHI) issues, exerting intense stress on residents. Based the observed temperature and PM2.5 concentrations Beijing over 2016–2020, we find diverse influences of aerosol pollution intensity (UHII) under different circulations. When northerly winds are prevalent Beijing, UHII tends be much higher both daytime nigh...

Large-scale human activity changes in megacities during Chinese New Year (CNY) are believed to significantly affect urban heat islands (UHIs). However, the urban-rural gradient UHI variations responsive cities remains largely unclear. Using in-situ surface air temperature obtained from a meteorological network that includes 3000-plus stations, we show mean intensity (UHII) 31 capitals is 0.52 ±...
