Estimating global warming from anthropogenic heat emissions
The forcing from the anthropogenic heat flux (AHF), i.e. the dissipation of primary energy consumed by the human civilisation, produces a direct climate warming. Today, the globally averaged AHF is negligibly small compared to the indirect forcing from greenhouse gas emissions. Locally or …

HOW URBAN DEVELOPMENT CONTRIBUTES TO THERMAL ENVIRONMENT VARIATION ---- A CASE STUDY IN NEW YORK CITY
The urban anthropogenic heat flux (AHF), which is one integral part of the deteriorating urban thermal environment, is seldom discussed for its ambiguity to accurately measure over heterogeneous land surfaces. Here, relying on remote sensing technology and meteorological models, AHF is estimated …

The curious case of urban heat island : a systems analysis
This thesis provides insights into the urban heat island (UHI) effect using a model of the urban microclimate that integrates the urban geometry, anthropogenic heat emission and the rural weather condition. The study builds upon the Urban Weather Generator (UWG), a numerical simulation program …

Implications of the Dense City Centre to Surface-Atmosphere Exchanges
… The focus is on the controls on radiation, anthropogenic heat and the turbulent latent and sensible heat fluxes. The impact of the composition and three-dimensional structure of the urban surface, plus the associated anthropogenic activities, are investigated using remote sensing techniques, …

Urban weather generator user interface development : towards a usable tool for integrating urban heat island effect within urban design process
… and accessible urban design tool to model urban heat island effect (UHI) from measurements at an operational weather station based on neighborhood-scale energy balances. The sensitivity analyses for Boston, MA, USA, and Punggol, Singapore identify as key parameters the building morphologies such …

Impacts of Urban Areas on Vegetation Development Along Rural-Urban Gradients in the Upper Midwest: 2003-2012
… evapotranspiration, releasing energy through anthropogenic heat sources, and increasing atmospheric aerosols, leading to increased temperatures in cities compared with surrounding rural areas, known as the “urban heat island” effect (Arnfield 2003). Recent urbanization of our planet has …

On the Improvements of Boundary-Layer Representation for High Resolution Weather Forecasting in Costal-Urban Environments
… can be better utilized to quantify the anthropogenic effects of these modifications. Although these systems have improved forecasting near-surface weather conditions, a comprehensive approach to represent urban impacts on the PBL is still limited. Improved PBL representation can lead to …

On the Energy Sustainability of Active and Passive Building Integrated Technologies in the Context of a Changing Climate for Tropical Coastal Cities
… is amplified in compact cities where anthropogenic heat removal from the built environment further increases the temperature of the urban canyon with feedback on human comfort and energy demands. Although there has been prior work reported on mitigating energy demands due to rising …

Urban scale phenomena and boundary layer processes in mountain valleys
… spatial scales. First the intensity of the Urban Heat Island (UHI) is analyzed evaluating the differences between air temperatures measured at an urban automated weather station on a tower, over mean rooftop level, and at five suburban/rural weather stations, located few kilometers around the city …
