Il fenomeno della sabbia del deserto spiegato da un meteorologo DOC: Marco Gaia
Ogni anno circa 500 milioni di tonnellate di sabbia vengono trasportate dal Sahara in varie parti del mondo, soprattutto verso l’Atlantico, ma anche verso di noi, in Europa. Particolarmente apprezzata dagli autolavaggi e dagli amanti delle albe rosse, meno amate dagli allergici e dagli automobilisti costretti spesso a ridurre le velocità in autostrada, queste polveri fini sono fondamentali a molti processi naturali. Di polvere sahariana abbiamo parlato con Marco Gaia responsabile del centro svizzero di meteorologia di Locarno Monti.
