Red sands: how to explain this phenomenon?

In Spain, Malaga looks like planet Mars. A rain of red sand from the Sahara covered this city in southern Spain three days ago. The residents were very surprised. How to explain this phenomenon ? It comes from a depression placed on the Iberian Peninsula, which brings up powerful winds from the Sahara, and carriers of sand. These winds carry tons of dust particles, and when it rains, the heaviest fall to the ground.

The phenomenon can be harmful for the most fragile, and it could intensify with global warming. “It can be indirectly linked to climate change, in the sense that the depressions tend to dip more towards the south of Europe. It is a fairly frequent phenomenon, but which mainly concerns, usually, the Iberian peninsula or the Canaries again”explains Pierre Huat, weather forecaster.
