Urban forestry and microclimate
2017This chapter presents knowledge concerning the effects of urban trees and forests on urban microclimate variables and human thermal comfort. Benefits of urban vegetation are evidenced by the growing interest on urban tree planting as an energy use control during summer. The chapter is divided into three sections. The first is dedicated to the effect of

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 ...

Designing the Urban Microclimate
Architecture and the Built Environment, 2015This doctoral thesis presents research on the integration and transfer of knowledge from the specialized field of urban microclimatology into the generic field of urban design. Both fields are studied in order to identify crosslinks and reveal gaps. The main research question of the research is: How can the design of urban neighbourhoods contribute to ...

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.

Microclimate Corrections for Urban Landscape Evapotranspiration
Impacts of Global Climate Change, 2005Landscape evapotranspiration (ET) can be estimated using reference evapotranspiration and “landscape” coefficient (KL) factors that adjust for differences between the vegetation and the reference surface. Difficulties in estimating ET of well-watered vegetation in urban settings result from local advection and edge effects, wide variations in radiation

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 ...
