Muzuva redu zuva nezuva tinoshandisa zvigadzirwa zvinoita kuti hupenyu hunyanye kusununguka; zvisinei, mamwe acho anokuvadza zvakanyanya, zvese pachedu uye nharaunda, sezvazviri nemaaerosols.
Kunyangwe zvingave zvisinganzwisisike, nekuda kwegomo reIcelandic tinogona kuziva maeerosols anokanganisa sei mamiriro ekunze.
Iyi igomo rinoputika zvikuru kuziva kuti maaerosols anokanganisa sei, kubvira pakati pa1783 na1784, kuputika kweLaki kweHoluhraun volcano kwaiburitsa sulfur dioxide kwemwedzi misere, zvichikonzera chikamu chikuru chezvimedu pamusoro peNorth Atlantic. Aya mapiritsi echisikigo yakaderedza saizi yemadonhwe egore, asi havana kukwidza huwandu hwemvura mavari sezvakawanikwa nechikwata chemasayendisiti chakatungamirwa neUniversity yeExeter (United Kingdom).
Nenzira iyi, vaongorori vanotenda kuti mhedzisiro yavo, iyo yakaburitswa muchidzidzo mumagazini 'muzvarirwo' inogona kudzikamisa kusagadzikana mune ramangwana mamiriro ekunze kutsanangura kukanganisa kwesurphate aerosols kubva mukugadzirwa kwemabhizimusi pane shanduko yemamiriro ekunze.
Aerosols inoshanda senuclei umo hutsi hwemvura mumhepo inonaya kugadzira makore. Nepo paine maindasitiri sulphate aerosols, kune zvimwe zvakasikwa sosi senge kuburitswa kwesulphur dioxide semhedzisiro yemakomo anoputika.
Munguva yekupedzisira kuputika kwegomo reHoluhraun, rakaitika muna2014-2015, yakaburitsa pakati pemakumi mana ezviuru nemazana zana ematani esarufa dioxide zuva rega rega panguva yechikamu chayo chekuputika. Nyanzvi dzakashandisa mamiriro ekunze emamiriro ekunze mamiriro, ayo, akabatanidzwa nedata rakawanikwa kubva kuNASA satellites, vakakwanisa kuona kuti saizi yemadonhwe emvura yakadzikira muhukuru, zvichikonzera chikamu chakakura chechiedza chezuva kuchiratidzwazve nzvimbo. Kuti, kunze kwakatonhora.
Naizvozvo, ivo vaongorori vanodavira kuti masisitimu egore "akanyatso chengetedzwa" pakushanduka kweaerosol mumhepo.
