I agree. This article may be based on the single source referenced here and the content could well be integrated in Urban heat island if it is relevant.
This is what the source says:
DUST DOME
The dome-shaped formation of stagnant and polluted air above a city is known as a dust dome. As any summer city-dweller eager to get to the country for a cool weekend knows, the air in an urban environment is often significantly warmer than air in the surrounding rural area, creating a phenomenon called the urban heat island. Industrial machinery and furnaces, manufacturing complexes, cars, and even air conditioners heat up the city’s air; building materials such as concrete, asphalt, and brick retain and radiate that heat well into the night. The large number of windows and other reflective surfaces serve to trap heat, and the lack of areas of open water sustains it. Soon the city is cooking; an inversion layer forms, which, because it’s capped at a relatively low level in the atmosphere, causes a dome of air pollutants to form over the city. If there is no wind, the dust dome remains intact, its pollutants sometimes growing a thousand times more concentrated over the urban area than in a nearby rural area. If the winds begin to blow strongly enough, however, the dust dome will elongate downwind, forming a dust plume. The city’s pollutants are then spread to its neighbors in the country.

It remains unclear, under which conditions and how often the inversion layer mentioned here would actually occur.
I think the article should be deleted. It uses only one, unreliable source. Any content worth keeping could be added to air pollution or urban heat island. EMsmile (talk) 11:57, 7 November 2023 (UTC)Reply
I found multiple papers on Google Scholar that mention this term but I didn't see any that were about urban heat domes; that said, I did not look very far. Google Books showed many citations; I did not examine them but they looked more usable for our purposes.
A merge with urban heat island remains a useful idea even if this topic is notable on a standalone basis.
