Urban climates and heat islands: albedo, evapotranspiration, and anthropogenic heat
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...
متن کاملChanges in Wind Speed under Heat Waves Enhance Urban Heat Islands in the Beijing Metropolitan Area
The interaction between urban heat islands (UHIs) and heat waves (HWs) is studied using measurements collected at two towers in the Beijing, China, metropolitan area and an analytical model. Measurements show that 1) the positive interaction betweenUHIs andHWs not only exists at the surface but also persists to higher levels (up to ;70m) and 2) the urban wind speed is enhanced by HWs during day...
متن کاملSynergistic Interactions between Urban Heat Islands and Heat Waves: The Impact in Cities Is Larger than the Sum of Its Parts*
Cities are well known to be hotter than the rural areas that surround them; this phenomenon is called the urban heat island.Heat waves are excessively hot periods duringwhich the air temperatures of both urban and rural areas increase significantly. However, whether urban and rural temperatures respond in the sameway to heat waves remains a critical unanswered question. In this study, a combina...
متن کاملVulnerability to heat waves: Impact of urban expansion scenarios on urban heat island and heat stress in Paris (France)
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...
متن کاملRemote sensing for urban heat and cool islands evaluation in semi-arid areas
Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...
