Tempestades de areia · Dust storms
Os grandes desertos do planeta estão sujeitos a fortes tempestades de areia que não só afetam regiões próximas, mas podem chegar até bem longe: há evidências de danos a recifes de corais no Caribe quando as tempestades do Saara são mais fortes. O site Earth Observatory da NASA disponibiliza várias imagens como essa, bem como de outros fenômenos de nosso planeta registrados por seus satelites.
The great deserts of the planet are subject to severe dust storms that affect not only the surrounding regions, but can reach very far: there is evidence of damage to coral reefs in the Caribbean when storms in Sahara are stronger. NASA’s Earth Observatory site provides many images like this, and of other phenomena of our planet captured by their satellites.
