The purpose of this investigation was to examine the current urban heat island (UHI) effect in a number of southeast Australian towns and to provide discussion on its potential impact on the historical temperature record. High-quality long-term historical temperature data are fundamental in the examination of climate change. Observational datasets are essential for the monitoring of climate and...

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...

Heat removal from street canyons to the urban boundary layer above buildings is one of physical processes that may largely determine (local) heat island (UHI) effects. Only few studies show impact a buoyant approaching flow on removal. In this study, we enhanced when more as induced by upwind convective heating heated ground surface. For purpose, perform simultaneous velocity and temperature fi...

BACKGROUND In recent years the developing world, much of which is located in the tropical countries, has seen dramatic growth of its urban population associated with serious degradation of environmental quality. Climate change is producing major impacts including increasing temperatures in these countries that are considered to be most vulnerable to the impact of climate change due to inadequat...

Lisbon is a European Mediterranean city, greatly exposed to heatwaves (HW), according recent trends and climate change prospects. Considering the Atlantic influence, air temperature observations from Lisbon’s mesoscale network are used investigate interactions between background weather urban thermal signal (UTS) in summer. Days classified prevailing regional wind direction, hourly UTS compared...

We present a first attempt to analyse the effect of large urban park (Parco Nord Milano—PNM) on Urban Heat Island (UHI) city area Milan. Specifically, analysis three cyclonic and anticyclonic circulation weather types (CWTs) frequency distribution daily thermal range (DTR) five stations in Milan shows stabilizing DTR when compared with suburban rural areas, generating modal class 4 °C winter 9 ...

Abstract Urban Heat Island (UHI) phenomenon is a particular climate change impact in urban areas that can trigger adverse effects on environmental conditions. This effect usually worsened by increasing anthropogenic activities. While the of UHI has mostly been studied metropolitans around world, few studies are presented investigating outcome mid-sized cities. study aims to assess spatial distr...

The urban heat island effect is a critical factor for air quality management and public health in urbanized areas of New Jersey. This effect is related to an increase in temperatures in urban areas as compared to surrounding lower density rural sites. The overall goal of the project was to contribute to effective regional environmental management under conditions of climate change. The related ...

The higher concentration of man-made objects like asphalt pavement and concrete structures within urban areas lead to the formation of subareas known as urban heat islands (UHI), where the ambient temperature is significantly higher. Having a good understanding of this problem is critical for better urban development. Thermal infrared (TIR, 8-12 μm) remote sensing is often used to localize UHI....
