Probleemi on p\u00f5hjustanud tuhapilved, mis on paiskunud \u00f5hku mitme kilomeetri k\u00f5rgusele. Vulkaanide l\u00e4hedal elavate islandlaste jaoks on elu muutunud drastiliselt. Pruun tuhakiht katab maju, teid ja p\u00f5lde. Samas on hiiglaslikud pilved liikunud tuhandeid kilomeetreid \u00fcle Euroopa, sundides paljusid lennukeid maale j\u00e4\u00e4ma.<\/p>\n<\/div>\n<p>Esimene purskamine algas 2010. aasta m\u00e4rtsis, kui Eyjafjallaj\u00f6kulli vulkaan hakkas paiskama auru- ja tuhapilvi. J\u00e4rgnevate kuude jooksul t\u00fchistati tuhandeid lende, kuna pisikesed osakesed levisid \u00fcle kogu Euroopa. P\u00e4rast purskamise l\u00f5ppemist normaliseerus lennuliiklus. Siis, 21. mail 2011, hakkas Gr\u00edmsv\u00f6tni vulkaan paiskama tuhka k\u00f5rgele atmosf\u00e4\u00e4ri. \u00d5nneks vaibus see purskamine \u00fcsna kiiresti, kuigi see oli eelmisest suurem. Mai l\u00f5puks oli lennuliiklus taastunud.<\/p>\n<p>Selliste vulkaanipurskete ajal on lennuettev\u00f5tjate ja valitsuste \u00fcks peamisi probleeme reisijate ohutuse tagamine. Kui lennuk lendab vulkaanilise pilve l\u00e4bi, satuvad tuhaosakesed reaktiivmootoritesse ja v\u00f5ivad p\u00f5hjustada mootori rikke. Tuhk v\u00f5ib ka lennuki v\u00e4lisk\u00fclge t\u00f5siselt kahjustada. Seet\u00f5ttu on h\u00e4davajalik leida viis, kuidas j\u00e4lgida pilve liikumist ja m\u00e4\u00e4rata kindlaks selle paksus.<\/p>\n<p>\u00d5nneks suudavad Maa orbiidil tiirlevad satelliidid, nagu ESA satelliit Envisat, tuhapilvi pildistada. Samuti suudavad nad tuvastada gaase, nagu v\u00e4\u00e4veldioksiid, mis on paisatud k\u00f5rgele atmosf\u00e4\u00e4ri ja j\u00f5uavad sageli regulaarlendude lennuk\u00f5rgusteni. Andmed saadetakse vulkaanilise tuha n\u00f5uandekeskustesse, mis hindavad v\u00f5imalikku ohtu lennundusele ja edastavad hoiatusi.<\/p>","protected":false},"excerpt":{"rendered":"<p>For the second time in a year, a volcanic eruption on Iceland has caused chaos across much of Europe.
