Satellitenbild der Woche: Wüstensand

(PresseBox) (Paris, )
Das Envisat-Bild zeigt Sand- und Staubwolken aus der Sahara. Sie treiben über Mauretanien (oben), Senegal (mitte), Guinea Bissau (unten) und über den Nordatlantischen Ozean, bevor sie nördlich in Richtung der kapverdischen Inseln geweht werden.

Sand-, oder Staubstürme sind gewöhnlich das Ergebnis atmosphärischer Konvektion, die sich bildet, wenn warme, leichtere Luft aufsteigt und kalte, schwerere Luft absinkt.

Winde können zwischen 60 und 200 Millionen Tonnen feinen Staub aus der Sahara hinaus tragen. Atmosphärische Konvektion, die auch Ursache für andere meteorologische Phänomene wie Gewitter sein können, können den Staub über tausende Kilometer transportieren.

Sandstürme treten häufig über der Sahara auf. Seo yhwk cne Jaajruynvxg qrj Pcxdkjfkwbhknm, ulg xh nurrrk Vyjlmfeeihacbmm dl zenuzkuphu Kdfhxvms ohj vnl Mmxknez bipgulcx.
