Atmospheric blocking is a long standing structure stalled in the mid-troposphere which is often associated with extreme weather events such as droughts, heatwaves, flood and cold air outbreak. A striking atmospheric blocking is identified to persist over the US during 13–17 August 2007, exacerbating the existing drought over the Southeastern US. This pronounced blocking event not only intensifi...

Cool roofs are a long-term alternative for the creation of building’s thermal comfort as they can reduce energy required cooling demands and mitigate urban heat island effect, thus benefitting both buildings cities. Interest in cool roofing has recently escalated numerous concepts, techniques, experiences represented various studies conducted hot climates; however, reviewing literature, it was ...

The European goals to reduce CO2 emissions by up 40% 2030 and reach carbon neutrality 2050 cannot ignore the building sector, that accounts for 27% of global greenhouse gas emissions. In context sustainable development goals, it is a key point consider reduction heat island effect in urban environment. Considering this background proven absence clear promotion mitigation measures, research aims...

This paper examines the utility of the air pollution Model (TAPM) in simulating meteorology and dispersion of PM10 and wind data in order to assess The Impacts of Wind Variability Function on Urban Heat Island for the day of 25, November, 2012 in Karaj city that experienced severe degradation in air quality. Drawing, Skew-T diagrams, maps of surface pressure (500hp), omega (850hp) and atmosp...

Although Land Surface Temperatures (LSTs) are on the rise globally, distribution of LSTs varies depending land cover type. Urban Heat Island and Cool effects act differently, especially in semi-arid regions. Therefore, we identify demi-decadal, seasonal, zonal differences a region city Jaipur, where zones include rural urban areas that encircle Jhalana Reserve Forest (JRF). After deriving from ...

This paper presents a methodology to approximate the urban heat island effect by using a PostgreSQL database and CitySim software, a simulation tool to evaluate urban energy flows. A ground temperature model has been developed for shallow depths (until 4m), which reproduces the phenomena of heat transfer into the ground on an hourly basis. This model is further used to predict the outdoor groun...

As an introduction to this special issue on urban heat islands and cool communities, this paper reviews some of the characteristics of urban climates and the causes and effects of urban heat islands. In particular, the impacts of surface albedo, evapotranspiration, and anthropogenic heating on the near-surface climate are discussed. Numerical simulations and field measurements indicate that inc...

in this study, the environmental effects of land use changes on vegetation cover and emitted land surface temperature in two urban and non-urban areas of ardakan in yazd province, iran, were studied and compared temporally, using remote sensing technique. for this purpose, contemporary land sat satellite images in 1990 and 2002 were acquired and used. then vegetation cover maps were generated u...
