For the past couple of days, we have been experiencing a weather phenomenon, known in Spain as a Calima. This is a sand and dust-laden wind, originating in the Sahara desert in North Africa.
A Calima wind generally raises temperatures but lowers visibility due to the fine yellowish-brown air-borne dust. You could be forgiven for thinking this was fog or industrial pollution and, indeed, a strong Calima may cause respiratory problems in humans.
This amazing photo by British astronaut, Tim Peake, from the International Space Station shows the huge sandstorm currently engulfing the Iberian peninsula.
But it’s not all bad news.
The particles contain vital nutrients and minerals which are good for fertilising both the land and the sea.
This weather phenomenon normally occurs around this time of year and lasts a few days leaving lots of cleaning up to do.
The good news is that the situation should improve by Thursday of this week, as a cold front introduces clearer air.
