* Release of humid ground-level air from an atmospheric vortex or solar chimney at altitude could form clouds or precipitation, potentially altering local hydrology.<ref>{{cite journal |doi=10.1016/j.atmosres.2008.05.003 |title=Numerical investigation of a plume from a power generating solar chimney in an atmospheric cross flow |journal=Atmospheric Research |volume=91 |issue=1 |pages=26–35 |year=2009 |last1=Zhou |first1=Xinping |last2=Yang |first2=Jiakuan |last3=Ochieng |first3=Reccab M. |last4=Li |first4=Xiangmei |last5=Xiao |first5=Bo |bibcode=2009AtmRe..91...26Z }}</ref><ref>{{cite journal |doi=10.1115/1.3028041 |title=Cloud Formation in the Plumes of Solar Chimney Power Generation Facilities: A Modeling Study |journal=Journal of Solar Energy Engineering |volume=131 |page=011009 |year=2009 |last1=Vanreken |first1=Timothy M. |last2=Nenes |first2=Athanasios |citeseerx=10.1.1.172.2449 }}</ref> Some of these ideas originated in work by Niewiadomski and [[Krzysztof Edward Haman|Haman]] who studied cooling tower dynamics.<ref>{{cite journal |doi=10.1016/0004-6981(84)90019-2 |title=The rainfall enhancement by washout of cooling tower plumes: A numerical experiment |journal=Atmospheric Environment |volume=18 |issue=11 |pages=2483–9 |year=1984 |last1=Niewiadomski |first1=Michal |last2=Haman |first2=Krzysztof E. |bibcode=1984AtmEn..18.2483N }}</ref> Local de-desertification, or afforestation could be achieved if a regional [[water cycle]] were established and sustained in an otherwise arid area.

* Fitted with a vortex chimney scrubber, the updraft could be cleaned of particulate air pollution. An experimental demonstration tower is cleaning the air in a Chinese city with little external energy input.<ref>{{cite news|last1=Chen|first1=Stephen|title=China builds 'world's biggest air purifier' (and it seems to be working)|url=http://www.scmp.com/news/china/society/article/2128355/china-builds-worlds-biggest-air-purifier-and-it-seems-be-working|access-date=22 January 2018|work=[[South China Morning Post]]|date=16 January 2018}}</ref><ref>{{cite news | url=http://www.digitaljournal.com/tech-and-science/technology/china-tests-giant-chimney-to-combat-air-pollution/article/516647 | title=China tests giant chimney to combat air pollution| newspaper=Digital Journal| date=2018-03-07}}</ref><ref name="nature.com"/> 
* Alternately to scrubbing, particulate air pollution caught in the updraft and released could serve as a nucleation stimulus for precipitation<ref>[[Cloud condensation nuclei]]</ref> either in the chimney, or at release altitude as [[cloud seeds]].
* Removal of urban air pollution raised and dispersed at altitude could reflect insolation, reducing ground-level solar warming.<ref>[[Smog tower]]</ref>{{Circular reference|date=April 2023}}
* Energy production, water desalination<ref name=Zhou10/> or simple atmospheric water [[solar cyclone|extraction]] could be used to support carbon-fixing or food-producing local agriculture,<ref>{{cite web|author=Tom Bosschaert |url=http://www.except.nl/consult/SolarUpdraftTower/solar_updraft_research.html |title=Solar Updraft Tower Research: Except Consulting |publisher=Except.nl |date=2008-09-26 |access-date=2011-09-11}}</ref> and for intensive [[algaculture|aquaculture]] and [[horticulture]] under the solar collector as a greenhouse.
*  A balloon-suspended lightweight extensible chimney anchored from an urban tether, rising from low level warm air to high altitude could remove low lying air pollution without the need for a broad collector at the base, given adequate height of release. This might improve air quality in highly polluted megacities without the burden and cost of major fixed construction.
