1. Introduction Urbanization is known to cause significant changes in the climatic properties of an area. Perhaps the most thoroughly documented consequence of this “inadvertent climate modification” is the urban heat island (UHI; Oke 1988 ). The magnitude of the UHI (Δ T u − r ) is roughly defined as the difference between the air temperature of the urban area T u and the air temperature of the surrounding rural area T r . Studies in cities across the globe have explored the meteorological

urban heat island (UHI) may develop, causing the city to remain consistently warmer than its surroundings. This phenomenon is created by changes in the natural environment caused by urban development and deforestation. Several studies have shown significant UHIs in major cities across the globe (e.g., Bornstein 1968 ; Oke 1973 ; Draxler 1986 ; Balling and Cerveny 1987 ; Lo et al. 1997 ; Bornstein and Lin 2000 ; Morris et al. 2001 ). In addition, much research has been done to determine how

mainly depends on the surface energy balance (SEB), which is influenced by alterations to the land characteristics due to human activities; the result of such direct and indirect modifications is urban warming ( Hinkel et al. 2003 ), or urban heat island (UHI), and the associated circulation ( Catalano et al. 2012a ; Ryu et al. 2013 ). There are cases where the latent heat flux in urban areas is higher than in rural areas (e.g., the city of Phoenix, built in a desert area), and thus the temperature

1. Introduction Many cities located in valleys with limited ventilation experience serious air pollution problems of concern for public health ( Edgerton et al. 1999 ; Romero et al. 1999 ; Panday and Prinn 2009 ). The transport of pollutants out of an urban valley atmosphere can be limited not only by orographic barriers, but also by urban heat island–induced circulations ( Haeger-Eugensson and Holmer 1999 ; Savijärvi and Liya 2001 ) and/or the presence of temperature inversions near the

1. Introduction Urban valleys can experience serious air pollution problems as a combined result of their limited ventilation and the high emission of pollutants from the urban areas (e.g., Rutllant and Garreaud 1995 ; Malek et al. 2006 ; Chu et al. 2008 ). In such complex terrains, the venting of pollution out of the valley is limited by the topography and can be further restricted by local circulations ( Gohm et al. 2009 ), and particularly by urban heat island–induced circulations

Introduction The urban heat island (UHI) phenomenon is mainly caused by the differences in the thermal structure between urban and rural environments that are associated with thermal properties of urban materials, urban geometry, air pollution, and the anthropogenic heat released by urban activities ( Park 1986 ). The phenomenon may occur during day or nighttime periods, and its spatial and temporal pattern is strongly controlled by the unique characteristics of each urban area ( Lyall 1977
