Kune hupenyu mumakoreKunze kwemvura inonaya, maaerosols, makristuru echando, kana guruva, timu yakabva kuUnited States yakawana kuti hupenyu huripo mumakore. Kunyangwe zvaifungidzirwa kubva kare kare, ikozvino tine humbowo chaihwo hwekuti izvi ndizvo chaizvo nekuda kwekuyedza kwavakaita.
Hongu, zvinokwanisika kuti kubva zvino zvichienda mberi apo patinosimudza maziso edu kumatenga uye tichiona makore, hazvidziviriki kufunga kuti kunyangwe mazviri mune zvipenyu. Asi ndozvazviri, uye nhasi ticha tsanangura kuti izvi zvinoitika sei. Nekuti pasi rino rinoramba riine zvishamiso nezvishamiso kwazvakaita sekunge zvese zvakatowanikwa.
Ndiani uye akaedza sei?
Chikwata muCalifornia, San Diego, uye iyo US Scripps Oceanographic Institution, vakatora madonhwe emvura nemvura yakasviba (chando) panguva yekubhururuka nepakati pemakore. Mukuwongorora kwakaitwa, vakaona kuti akanyorwa, kuwedzera kune guruva uye nezvimwe zvinhu zve organic, nemabhakitiriya, fungus spores uye zvimwe zvisaririra zvemiti. Iko kuongorora chaiko kwaive kuyedza kufunga kuti vanokanganisa sei kuumbwa kwegore.
C-130 ndege
Ongororo yacho yakatorwa nendege yeC-130 kuburikidza nemakore. Ndege yaive neyakavakirwa-mukati mass spectrometer uye nechando kamuri. Kuyerwa kwemasampuli kwakatorwa "in situ", saka zvakakosha kuti uone kuti kuyerwa kwakarurama pasina kubvumira zvimwe zvikonzero kukurudzira.
Vakasimuka sei ipapo?
Imwe yemhedziso iyo masayendisiti akasvika ndeye mhepo inoyerera. Semuenzaniso, mhepo dzejecha dzinogona kukonzerwa muAsia, dzinobatsira kuumbwa uye kuumbika kwemadonhwe emvura mumakore. Izvi pavanosimuka vanotakura guruva, marondedzero atakaita, uye pakati pavo spores yefungus, bacteria, etc. Izvi zvinotevera, saka, kuti mvura inonaya muAmerica, inogona kutakura mabhakitiriya kubva kuAsia.
Anne-Marine Schmoltner we National Science Foundation yeAmerica (NFS), vanova ndivo vakatsigira chirongwa ichi, vakati: "izvozvi zvaonekwa kuti kwete guruva risingaiti chete, asi nezvidimbu zvehupenyu, zvinoita basa rinokosha mukuumbwa kwemakore."
Chokwadi zvakakwana, kubva zvino zvichienda mberi, kana iwe ukatarisa "kumusoro uko," iwe uchaona chimwe chinhu chinopfuura kungodzikiswa kwemhute yemvura.
