Ukurekhodwa kwezandi zeZibane zaseMntla, ezibonisa ukuba le nto ixhaphake kakhulu kunokuba bekucingelwa ngaphambili, kwaye iyenzeka naxa ingabonwa, yenziwe ngu-Unto Kalervo Laine - owayengunjingalwazi kwiYunivesithi yaseAalto eFinland kunye nengcali kwitekhnoloji yentetho. Unikeze ingxelo kwinkomfa yamva nje ye-EUROREGIO / BNAM2022 acoustics eDenmark. Kangangeminyaka emininzi, uLaine ebefunda izandi ezinxulumene nezibane zaseMantla. Kwi-2016, wapapasha ulwazi lokuba ukurekhodwa kwe-popping ngexesha le-aurora borealis kwakuhambelana neeprofayili zokushisa ezibhalwe yi-Finnish Meteorological Institute (FMI). Ezi datha azibonisi kuphela ukuba i-auroras inokunxulunyaniswa nezandi, kodwa iqinisekisa kwakhona ithiyori ye-Lane yokuba ezi zandi ziphuma ekukhutsheni kombane kumaleko we-inversion wobushushu kumphakamo omalunga neemitha ezingama-70 ngaphezulu komhlaba. Imizekelo emitsha yezibane ezisemantla zarekhodwa ebusuku kufutshane nedolophana yaseFiskars. Nangona ukukhanya kwakungabonakali ngelo xesha, ushicilelo lukaLane lwabamba amakhulu “ezandi ezivakalayo. Xa iirekhodi zithelekiswa nemilinganiselo yemisebenzi ye-FMI geomagnetic, ulungelelwaniso olomeleleyo olucacileyo lwafunyanwa. Zonke izandi ezingama-60 ezigqwesileyo zabagqatswa zayanyaniswa notshintsho kwindawo ye-geomagnetic. "Ukusebenzisa idatha ye-geomagnetic eye yalinganiswa ngokuzimeleyo, kunokwenzeka ukuqikelela ukuba izandi ze-aurora borealis ziya kuba zichaneke ngama-90%," utshilo uLaine. Uhlalutyo lwakhe lwamanani lubonisa ubudlelwane obucacileyo phakathi kwe-geomagnetic oscillations kunye ne-auroras.
Ekupheleni kuka-Matshi ka-2022, iingcali ze-NASA zabelana ngezicwangciso zokuqalisa iirokethi ezimbini kumphakamo ongaphezu kwe-200 km ngokuthe ngqo kwizibane ezisemantla ukuze zifunde ngokweenkcukacha iinkqubo zotshintshiselwano lwamandla phakathi koMhlaba kunye nendawo engaphandle. Oku kuchazwe yi-portal ye-NASA. Ukukhanya kuzalelwa kumda phakathi kwemeko yombane engathathi hlangothi ejikeleze iplanethi kunye nesithuba se-interplanetary esizaliswe ngamasuntswana ahlawuliweyo avela kwiplasma yomoya welanga, esebenzisana nentsimi ye-geomagnetic. Ukukhanya kwe-luminescent okuphuma ngezantsi kujongeka njengeeseyile ezinkulu ezinemibala eyahlukeneyo kunye namaza okukhanya okudanisa. Kodwa umfanekiso awuphelelanga nje kumboniso womhlaba – intsebenziswano phakathi kwamasuntswana avuselela imida ebanzi yomaleko we-atmosfera, kwaye yimpembelelo yamasuntswana ahlawuliweyo kolu maleko ungasentla enomdla kwiNASA. I-arhente ilungiselela namhlanje e-Alaska i-INCAA mission - i-Ionic neutral compound ngexesha lokukhanya okusebenzayo. Akukho mda ocacileyo woluhlu apho igesi engathathi hlangothi iphela kwaye i-plasma iqala - kukho umda omkhulu womda apho iintlobo ezimbini zeengqungquthela zixubene, ezithi ngezikhathi ezithile zidibanise kwaye zikhuphe iifotoni zamaza ahlukeneyo. Umbala "weeseyile" uxhomekeke ekubunjweni kweeamolekyu ze-atmospheric: i-oksijeni inika ukukhanya okuluhlaza okuluhlaza okanye okubomvu, i-nitrogen - ebomvu okanye emfusa. I-rocket yokuqala icwangciswe ukuba ikhuphe izibonakaliso zomphunga ezingenabungozi - iikhemikhali ezinemibala efana naleyo isetyenziswe kwi-fireworks - ngaphambi kokufikelela kubude obuphezulu be-300 km. Iimpawu zomphunga ziya kudala amafu abonakalayo anokuthi abaphandi bajonge ukusuka emhlabeni, ngaloo ndlela belandelela imisinga yomoya kufutshane nokukhanya. Irokethi yesibini, eza kuqaliswa kamsinya nje emva kweyokuqala, ifikelele kumphakamo omalunga neekhilomitha ezingama-200, iya kulinganisa ubushushu kunye nokuxinana kweplasma ngaphakathi nangaphandle kokukhanya.
