Urban Microclimates and Simulation
2013This chapter examines the workings of urban microclimates and looks at the associated causes and effects of the urban heat island (UHI). It also clarifies the relationship between urban form and the key climatic parameters (sun, daylight, wind, and temperature). A particular section is devoted to the concepts of UHI intensity and sky view factor (SVF);

MICROCLIMATES WITHIN AN URBAN AREA∗
Annals of the Association of American Geographers, 1977The geographic delineation of various microclimates within an urban area is determined by the transfers of energy, mass, and momentum at the city surface. This approach requires a method for quantifying urban surface characteristics. The results of specifying the surface textures of Sacramento, California, and the determination of the attendant ...

Trees Modify the Urban Microclimate
Arboriculture & Urban Forestry, 1976A person's feeling of thermal comfort is affected by environmental conditions, including solar radiation, air temperature, wind, humidity, longwave radiation, and precipitation. Trees modify all of these variables and therefore affect individual thermal comfort. Shade and wind protection are wellrecognized efforts.

Extracting Urban Microclimates from Electricity Bills
Proceedings of the AAAI Conference on Artificial Intelligence, 2017Sustainable energy policies are of growing importance in all urban centers.Climate — and climate change — will play increasingly important roles in these policies.Climate zones defined by the California Energy Commissionhave long been influential in energy management.For example, recently a two-zone division of Los Angeles(defined by ...

Urban microclimates: mitigating urban heat
2014The urban heat island is among the more documented phenomena of climate change. It describes the high ambient temperatures in the dense zones of a city compared to its surroundings. This chapter presents the main developments in the area of urban mitigation technologies and, in particular, the most recent achievements and knowledge in the field of cool ...

Microclimates in tropical urban complexes
Energy and Buildings, 1990Abstract Irrespective of the location, heat islands are formed either at highly commercial places or densely populated areas. Utilizing the traditional airport meterological data and city centre data, diurnal, seasonal and annual variations of temperature, dew point, winds, visibility, stability, mixing height and ventilation coefficient and the ...

Impact of rapid urbanization on microclimate of urban areas of Pakistan
Air Quality, Atmosphere & Health, 2014Urbanization tendency is growing rapidly in the developing countries. It may cause microclimatic change in these areas. Therefore, it is necessary to investigate the impact of past and present urbanization on the microclimate of cities. Microclimatic change and its relation to the rapidly increasing population in a northern city (Abbottabad) of ...

Urban Greening and Microclimate Modification
2017Vegetation is promoted widely all over the world as a means of creating a better quality of life in cities. Plants are credited with lowering air temperature and development of green spaces is considered one of the main strategies for mitigating the urban heat island.
