MICROCLIMATES WITHIN AN URBAN AREA∗

Annals of the Association of American Geographers, 1977
The 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 ...

Study of the urban microclimate using thermal UAV. The case of the mid-sized cities of Arica (arid) and Curicó (Mediterranean), Chile

Building and Environment, 2021
The study of the urban microclimate requires detailed information that is not available in most cities. The monitoring of climate parameters is reduced to a limited number of stations that are useful for urban climate studies at local or zonal scales ...

Trees Modify the Urban Microclimate

Arboriculture & Urban Forestry, 1976
A 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, 2017
Sustainable 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

2014
The 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 ...

Impact of rapid urbanization on microclimate of urban areas of Pakistan

Air Quality, Atmosphere & Health, 2014
Urbanization 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 ...

Microclimates in tropical urban complexes

Energy and Buildings, 1990
Abstract 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 ...

Urban Greening and Microclimate Modification

2017
Vegetation 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.
