urban heat islandA barrier to urban heat island (UHI) mitigation is the lack of quantitative attribution of the various contributions to UHI intensity. This study demonstrates the daily and seasonal dynamics of UHIs in Hong Kong, a subtropical high銉緀nsity city. The nocturnal UHIs of the ...
Urban heat island Synoptic pattern Mixing layer height Ambient pollution Atmospheric boundary layer Wind Meteorological factors 摘要 The purpose of this study is to evaluate the influence of synoptic pattern, as well as other corresponding boundary layer dynamic characteristics, on PM10 concentrations and ...
This study examines the characteristics of the urban heat island (UHI) in Dhaka, the densely populated capital city of Bangladesh under the influence of the South Asian monsoon, and its interaction with heat waves. For this, meteorological data at Dhaka (urban) and Madaripur (rural) stations an...
We incorporated a single-layer urban canopy model into a simple two-dimensional atmospheric model in order to describe the fundamental impact of the urban canopy model on an idealized urban heat island simulation. We found that the heat island circulation developed less strongly than when using the...
Impacts of urbanisation on the thermal behaviour of new built up environments: A scoping study of the urban heat island in Bahrain Urban grids and structure have a significant impact on the thermal behaviour of newly developed built up areas. Human comfort is improved in the presence ... FS ...
sea-land breeze circulation and the urban heat island effect14,15,16,17can affect the ABL structure in the NCP, which further affect the spatiotemporal distribution of air pollutants18,19. Some studies have found an inhomogeneous spatial distribution of pollution in the NCP27,70,73,74. To inv...
Even small towns of a few thousand population create an effect on temperatures and have an ‘urban heat island,’ and large cities like New York create much higher temperatures ranging from 3 to 7 °C above rural values. Cities are major converters of energy and matter, and their products ...

In cities and towns, the urban heat island effect13,14 is well known to affect local atmospheric conditions. Here, we assessed the wind plant wake effect on local atmospheric conditions at the U.S. Department of Energy’s ARM SGP site in northern Oklahoma. Recent increases in wind energy ...
For example, we have long known that urban areas affect microclimate; in fact, the urban heat island was first described nearly two centuries ago. We also know that human activities generate emissions that are precursors of ozone, a primary constituent of photochemical smog in cities, and we ...
