Abstract. Global warming is causing increasing Heat Waves that affect human health. High temperatures markedly increase morbidity and mortality. Urban Islands the effects of are a serious inconvenience to health comfort. Cities can substantially local reduce temperature drop at night. During night, greater thermal inertia central areas reduces their cooling capacity. On other hand, it important...

With growing urban populations, methods of reducing the heat island effect have become increasingly important. Cool pavements altering storage materials used in can lead to lower surface temperatures and reduce thermal radiation emitted atmosphere. pavement technologies utilize various strategies temperature new existing pavements, including increased albedo, evaporative cooling, reduced conduc...

Green areas cool the climate of a city, reduce the energy consumption caused by the urban heat island (UHI) effect, and bring along carbon savings. However, the calculation of carbon savings due to the cooling effect of green areas is still not well understood. We have used a Landsat Enhanced Thematic Mapper Plus (ETM+) image of Beijing, to identify the cooled areas, compute the possible energy...

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 atmospher...

While numerous studies have examined the magnitude of the urban heat island, no large-scale study has yet analyzed its variability using an air-mass based methodology. The air-mass approach can provide unique insight by discerning how large-scale weather patterns may impact the magnitude of the heat island effect. This study utilizes the Spatial Synoptic Classification (SSC) scheme, a recently-...

We incorporated a single-layer urban canopy model into a simple two-dimensional atmospheric model in order to describe the fundamental impact of the urban canopy model on an idealized urban heat island simulation. We found that the heat island circulation developed less strongly than when using the atmospheric model with the standard slab urban model. Additionally, the coupling with urban canop...

It is well-known that the occurrence of urban heat islands (UHI) related to climate change and urbanization. Urban locations experience local overheating throughout summer, which uncomfortable it has a detrimental impact on buildings ability consume energy. In this study, methodology was developed assess island effect in localized area evaluate effects different kind mitigation strategies. The ...

Heat-wave risk in cities is determined both by regional climate evolutions and by cities size and shape change, because they can impact heat island effect. Land planning and urban transport policies, due to their long-lasting impact on cities shape, can therefore play a role in heat-wave risk mitigation. However, the link between these policies and resulting change in urban heat island is far f...
