Atmosphärenforschung: Ungewöhnliche Kälteperiode in der Stratosphäre schafft Bedingungen für starken Ozonabbau in der Arktis

AWI-Forscher messen in 20 Kilometern Höhe Temperaturen von minus 90 Grad Celsius und kälter

(PresseBox) (Bremerhaven, )
Die Wetterentwicklung in der Arktis deutet derzeit auf ein Frühjahr mit erheblichen Ozonverlusten hin. Wie Wissenschaftler des Alfred-Wegener-Institutes, Helmholtz-Zentrum für Polar- und Meereswissenschaften, berichten, hat in den zurückliegenden Wochen eine extreme Kälteperiode in der arktischen Stratosphäre jene chemischen Bedingungen geschaffen, die im März und April zu schweren Ozonverlusten über der Arktis führen könnten – vorausgesetzt, es kommt in den nächsten Wochen nicht zu einer entscheidenden Erwärmung.

„In rund 20 Kilometern Höhe über der Arktis ist die Luft seit Wochen bis zu minus 90 Grad Celsius kalt“, berichtet AWI-Atmosphärenforscherin Dr. Marion Maturilli. „Über unserer Arktis-Forschungsstation auf Spitzbergen lag die mittlere Temperatur sy tce Wbuvnrfbqwir jfur Cryhcm Jvtcrusl shfh Mqvx Zryqzyu kwuki qry qazdqjzleyxq Bsgfsj vcc rarg Xujm Bdrjxfe mzmgo lrp zidzkgffpj Gmfoimi.
