Seasonal and Spatial Characteristics of Urban Heat Islands (UHIs) in Northern West Siberian Cities
Anthropogenic heat and modified landscapes raise air and surface temperatures in urbanized areas around the globe. This phenomenon is widely known as an urban heat island (UHI). Previous UHI studies, and specifically those based on remote sensing data, have not included cities north of 60◦N. A few in situ studies have indicated that even relatively small cities in high latitudes may exhibit sig...
متن کاملUrban 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 کاملDeveloping High-Resolution Descriptions of Urban Heat Islands: A Public Health Imperative
Empirically derived 1-m–resolution descriptions of (A) morning and (B) evening urban heat islands in Portland, Oregon, on August 25, 2014. Temperatures were recorded in 1-hour periods at 6 AM and 7 PM. In the morning, low-lying vegetation cover had the strongest effect on temperature; in the evening, temperatures were most strongly affected by variation in building heights. High-resolution data...
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 ...
متن کاملUrban heat islands in China enhanced by haze pollution
The urban heat island (UHI), the phenomenon of higher temperatures in urban land than the surrounding rural land, is commonly attributed to changes in biophysical properties of the land surface associated with urbanization. Here we provide evidence for a long-held hypothesis that the biogeochemical effect of urban aerosol or haze pollution is also a contributor to the UHI. Our results are based...
