Alates 1985. aastast on teadlased j\u00e4lginud Antarktika kohal asuvat osoonikihi auku. Loodeti, et osooniauk hakkab j\u00e4rk-j\u00e4rgult kahanema, kuid ESA kosmosesondi Envisat uued andmed on n\u00e4idanud, et osoonikadu on olnud suurem kui kunagi varem.<\/p>\n<\/div>\n

2. oktoobril tehtud m\u00f5\u00f5tmised n\u00e4itasid 40 miljoni tonni v\u00e4henemist, mis \u00fcletas 2000. aasta eelmise rekordi. Lisaks h\u00f5lmab t\u00e4navune osooniauk 28 miljoni ruutkilomeetri suurust ala, mis on peaaegu sama suur kui 2000. aasta auk. Ka osooniaugu s\u00fcgavus on v\u00f5rreldav varasemate rekordv\u00e4\u00e4rtustega.<\/p>\n

\u201cSelline m\u00e4rkimisv\u00e4\u00e4rne osoonikadu eeldab stratosf\u00e4\u00e4ris v\u00e4ga madalaid temperatuure koos p\u00e4ikesevalgusega,\u201d \u00fctles ESA teadlane Claus Zehner. \u201cSelle aasta \u00e4\u00e4rmist osoonikadu saab seletada sellega, et Antarktika kohal ulatusid temperatuurid umbes miinus 92 Celsiuse kraadini \u2013 see on madalaim temperatuur, mis selles piirkonnas alates 1979. aastast on registreeritud.\u201d<\/p>\n

Osoonikihi h\u00f5renemine L\u00f5unapooluse kohal<\/figcaption><\/figure>\n

Osoon on hapniku gaasiline vorm. See moodustab 25\u201340 km k\u00f5rgusel Maa kohal kihi, mida nimetatakse stratosf\u00e4\u00e4riks. Osoonikiht on oluline, sest see blokeerib P\u00e4ikeselt p\u00e4rinevaid kahjulikke ultraviolettkiiri. Need kiired suurendavad nahav\u00e4hi ja silmakatarakti tekke riski ning m\u00f5jutavad mereelustikku.<\/p>\n

Osoonikihi h\u00f5renemise p\u00f5hjuseks on inimtekkelised saasteained, nagu n\u00e4iteks kloor, mis p\u00fcsivad atmosf\u00e4\u00e4ris mitu aastat. Kui saabub polaarne kevad, vabastab p\u00e4ikesevalgus k\u00f5rgetes pilvedes kinni j\u00e4\u00e4nud kloori. Seej\u00e4rel h\u00e4vitab kloor ozooni kiiresti.<\/p>\n

See auk p\u00fcsib tavaliselt novembrini v\u00f5i detsembrini, mil Antarktika kohal asuv osoonivaene \u00f5hk hakkab segunema v\u00e4ljastpoolt tulevaga osoonirikka \u00f5huga.<\/p>","protected":false},"excerpt":{"rendered":"
