Abstract. The urban climate literature has highlighted the remarkable prominence of nighttime UHI phenomenon. During effects become more evident due to greater thermal inertia materials used in fabric. It is during night when heat accumulated materials, especially contexts waves, can generate significant health risks. low cooling capacity construction negatively affects comfort and dwellers. Ho...
This study presents a method used for predicting the air temperature distribution in an urbanized area from the surface temperature of trees. A strong trend of urbanization can be observed whole over the world (United Nations Centre for Human Settlement, 1996). It is well known and documented that urbanization can have significant effects on local weather and climate (Landsberg, 1981). One of t...
In urban areas, main air flows from prevailing winds are strongly modified, depending on constructions’ morphology and urban microclimate’s effects. The meteorological data on the wind speed are often available from outside city centres whereas this wind speed is tough to assess in the urban canopy layer. The meteorological models which are developed from regional level to urban canopy layer le...
Radiative balance and heat storage capacity modifications play a major role in urban heat island formation. Urban shape determines the receipt and loss of radiation and consequently the heat storage potential, thus resulting in a higher air temperature. In order to analyze the interactions between climate and urban shape, the territory is partitioned from the road network into elementary areas:...
Global climate change increases heat loads in urban areas causing health and productivity risks for millions of people. Inhabitants in tropical and subtropical urban areas are at especial risk due to high population density, already high temperatures, and temperature increases due to climate change. Air conditioning is growing rapidly, especially in South and South-East Asia due to income growt...
This article presents a study of residential parcel design and surface heat island formation in a major metropolitan region of the southeastern United States. Through the integration of high-resolution multispectral data (10m) with property tax records for over 100,000 single-family residential parcels in the Atlanta, Georgia, metropolitan region, the influence of the size and material composit...
The spatio-temporal patterns of land use/land cover changes (LUCC) can significantly affect the distribution and intensity of the urban heat island (UHI) effect. However, few studies have mapped a clear picture of the influence of LUCC on UHI. In this study, both qualitative and quantitative models are employed to explore the effect of LUCC on UHI. UHI and LUCC maps were retrieved from Landsat ...
In this paper, we present surface urban heat island (SUHI) analysis of Shanghai (China) based on the change in land use and land cover using satellite Landsat images from 2002 to 2013. With the rapid development of urbanization, urban ecological and environmental issues have aroused widespread concern. The urban heat island (UHI) effect is a crucial problem, as its generation and evolution are ...
