    en.wikipedia.org/wiki/Reflective_surfaces...

    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.

  8. Urban thermal plume - Wikipedia

    en.wikipedia.org/wiki/Urban_thermal_plume

    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.
