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 ]
The urban environment has two atmosphere layers, besides the planetary boundary layer (PBL) outside and extending well above the city: (1) The urban boundary layer is due to the spatially integrated heat and moisture exchanges between the city and its overlying air. (2) The surface of the city corresponds to the level of the urban canopy layer.

Heat-related deaths surge by 117% since 1999, exceed 20,000 fatalities
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.
