A definition of urban heat island is: "The relative warmth of a city compared with surrounding rural areas." [14]: 2926 This relative warmth is caused by "heat trapping due to land use, the configuration and design of the built environment, including street layout and building size, the heat-absorbing properties of urban building materials, reduced ventilation, reduced greenery and water ...
Unequal threat of heat stress in urban environments is often correlated with differences in demographics, including racial and ethnic background, income, education level, and age. [1] While the general impacts of urban heat inequity depend on the city studied, negative effects typically act on historically marginalized communities. [ 1 ]
This is known as the urban heat island effect, and it means that urban cities can have daytime temperatures up to 7 degrees Fahrenheit warmer, and nighttime temperatures up to 5 degrees F hotter ...
Maps of each city revealed how different land use and urban growth patterns influence urban heat island hotspots. Some cities, like Bakersfield and Tulsa, were marked by a heat intensity peak in ...
An urban thermal plume describes rising air in the lower altitudes of the Earth's atmosphere caused by urban areas being warmer than surrounding areas. Over the past thirty years there has been increasing interest in what have been called urban heat islands (UHI), [1] but it is only since 2007 that thought has been given to the rising columns of warm air, or ‘thermal plumes’ that they produce.
Urbanization additionally affects land cover through the urban heat island effect. Heat islands occur when, due to high concentrations of structures, such as buildings and roads, that absorb and re-emit solar radiation, and low concentrations of vegetative cover, urban areas experience higher temperatures than surrounding areas.

Amid record-breaking heat across the U.S., residents in major cities like Phoenix and Miami are experiencing far more intense weather than those in rural areas. Millions of Americans are stranded ...
Mechanism of the urban heat island effect: the densely-built downtown areas tend to be warmer than suburban residential areas or rural areas. ... Original images ...
