I saw an exchange of comments and couldn’t stop laughing:
You can’t do this without outlawing combustion. While it’s a nice theory to say that you’ll be able to blow enough air through it, in practice the airflow in a dome is not like the airflow without a dome. And anyone who has been to Houston knows just how bad the air quality is, in fact, it is some of the worst in the USA [nasa.gov]. If you could remove Chinese pollution from the Jet Stream, it probably WOULD be the worst. Then again, if you put a dome over it, the city’s residents could just gas each other to death, which would effectively stop them from polluting.
