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 ...
While the general impacts of urban heat inequity depend on the city studied, negative effects typically act on historically marginalized communities. [1] The idea is closely tied to the urban heat island effect, where a major cause to urban heat inequity is increased urbanization. [2]
The Big Apple is one of many cities around the world that is impacted by the urban heat island effect, a phenomenon where urban areas are warmer than their surrounding suburbs. Speaking of ...
A heat dome is a weather phenomenon consisting of extreme heat that is caused when the atmosphere traps hot air as if bounded by a lid or cap. Heat domes happen when strong high pressure atmospheric conditions remain stationary for an unusual amount of time, preventing convection and precipitation and keeping hot air "trapped" within a region.
According to the U.S. Environmental Protection Agency, the urban heat island effect raises temperatures in areas with dense concentrations of pavement, buildings and other surfaces that retain heat.
An urban heat island occurs where the combination of heat-absorbing infrastructure such as dark asphalt parking lots and road pavement and expanses of black rooftops, coupled with sparse vegetation, raises air temperature by 1 to 3 °C (1.8 to 5.4 °F) higher than the temperature in the surrounding countryside.

More than 40 million Americans in cities live with the impact of the “heat island” effect, in which city centers absorb more heat than surrounding areas, according to an analysis published ...
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.
