Urban Heat Island
We are all familiar with the fact that cities are generally warmer than the surrounding, more rural areas. We see it referenced most nights in our television weather reports. It is especially significant on nights with clear skies and light winds which favor radiational cooling. This is most significant in the rural areas but in the city, the excess heat absorbed during the day and the local he...

متن کاملMapping Manchester’s urban heat island
An urban heat island (UHI) is a phenomenon whereby urban areas experience elevated temperatures relative to the surrounding rural hinterland. This thermal contrast is brought about by anthropogenic modification of the environment. For example, there is little bare earth and vegetation in urban areas. This means that less energy is used in evaporating water, less of the Sun’s energy is reflected...
متن کاملThe London Urban Heat Island – Upwind Vegetation Effects on Local Temperatures
Vegetation has the potential to cool the air in contact with it through evaporation of surface and transpirated water. This effect may have significant benefits in reducing the need for mechanical cooling of a building or increase comfort in outdoor spaces. The actual depression in air temperature is variable and uncertain in its degree and reach. Data from a large measurement exercise in Londo...
